Suppose public-key cryptography is used to encrypt the communications between Alice and Bob. Alice\'s public key is eA, private key is dA; Bob\'s public key is private key is de. Now Bob wants to send a message m to Alice. Describe which keys should be used to encrypt the message and decrypt the ciphertext. Solution Answer:- Bob\'s message is encrypted using eA and when Alice receives message from Bob it is decrypted using dB Explanation:- *In public key cryptography, each user has two keys and each user publishes one key (public key) keeping another key private (private key). *Consider two users A and B, if A wants to send a message to B , A\'s message is encrypted using B\'s public key. When B receives message from A , it is decrypted using B\'s private key..

Pluto has been hard to measure from Earth because of its atmosphere. .pdf
Pluto has been hard to measure from Earth because of its atmosphere. In 2007 Young, Young,
and Buie measured Pluto as having a diameter of 2322 km. The New Horizons probe traveled to
Pluto and measured it up close and we now know the actual size is 2372 km. What was the
percent error of the 2007 measurement?
Solution
Percentage error: (2372-2322)*100/2372 % = 2.108%.

Loops and Arrays
Objectives:
Arrays are a series of elements consisting of the same type (For ex: all integers), in a contiguous
chunk of memory. The elements can be individually referenced by indexing the array.
You must specify the type of data stored in an array, and each element in any array must be of
the same type.
An array has a static size -- they cannot grow any larger than the size you tell it to be when you
create it.
To access the value at that index of the array: for (int i = 0; i < 10; i++){
cout<< intArray[i]<< endl; }
To access the memory address of the array element: for (int i = 0; i < 10; i++){
cout << intArray + i << endl; }
Creating an Array and Initializing
When you declare an array, you will get an uninitialized section of memory. If you want to
create an array of numbers, you would do:
int intNumbers [10];
double dblNumbers[10];
Then, putting element in the array can be set up by using the index of the array element you want
to change:
intNumbers[0] = 3; intNumbers[1] = 5; intNumbers[2] = 6; intNumbers[3] = 8;
1. Write a program that uses a for loop.
2. Declare and initialize and array.
3. Practice the array operations print and modify.
When you create an array, you do so to capture a group of items that all need to be treated
separately, but also need to grouped together for some purpose. For example, when you think
about a song, each note in the song is a separate sound, but they all need to be included together
in a certain order to make up the song.
To initialize the array:
int intNum [5] = {16, 3, 20, 4, 21}; (Hint: notice the syntax difference initializing this array
versus the one above)
Retrieving/Adding/Changing elements
To access or retrieve individual elements in an array, the syntax is square brackets and the
element index (starting from 0):
intNumbers[0]; will be the first item in the intNumbers array. intNumbers[1]; will be the second
item in the intNumbers array.
Below is an example of a basic 2D array. It shows how we access certain elements shown in the
arrayName[row][column] format. This will be helpful for a future assignment.
We can change the values in the array using the index of the individual items, such as
Example 1:
int intNumbers[2];
intNumbers[0] = 5;
intNumbers[1] = 7;
intNumbers[1] = intNumbers[1] * 2 cout << intNumbers[1] << endl;
Example 2:
//this will print the value 14
intNumber[1] = 10;
Example 3:
for (int i = 0; i < 10; i++){
intArray[i] = i;
cout << intArray[i] << endl;
//this will update the value to 10 at that index
//will set what the values are in that position //will print out the value of i at each index
}
TO DO: Create an array in your main function
1) Create an array of 20 doubles, using a variable name of your choosing. Assign values to your
array using a for loop:
for (int i = 0; i < 20; i++) myDoubles[i] = i;
where myDoubles is the name of the variable created.
2) Print out the values in another for loop using: cout << “Stuff to print” << endl;
3) Now, using your array an.

Use the UNION statement to provide a combined listing of care center names and their locations
as well as laboratories and their location. The list should be sorted by location, in ascending
order. (You should use aliases to rename the fields in this query.)
Please provide results!
Solution
The UNION operator is used to combine the result-set of two or more SELECT statements.The
UNION operator selects only distinct values by default. To allow duplicate values, use the ALL
keyword with UNION.
Syntax:
SELECT column_name(s) FROM table1
UNION ALL
SELECT column_name(s) FROM table2;
Now Let us consider that there are two tables namely care_center_t and laboratory_t where the
care_center_t contains rows like care_center name ,location1 and the laboratory_t consists of
rows such as laboratories and Locations2.
SELECT operator is used in selecting of particular rows from the table. So, now we select rows
namely care_center_name and location1 from care_center_t table and Loboratories and location2
from laboratory_t table.
The Database Query for the above problem is
SELECT care_center_name as name,location1 as location from care_center_t
UNION all
Select laboratory as name ,location2 as location from laboratory_t.
Let f X Y be a function.True or FalseA sufficient condition for f .pdf
Let f: X Y be a function.True or False?A sufficient condition for f to be one-to-one is that for all
elements y in Ym there is at most one x in X with f(x)= y.
Solution
true.
A function f from X to Y is called one-to-one (or 1-1) if whenever
f (x) = f (y) then x = y.
No element of Y is the image of more than one element in X.
that is one-one function has an inverse that is also a function..

It\'s your third week on the job at Panache Inc. Last week, you made sure all investment
transactions for trading, available-for-sale, held-to-maturity, and equity securities were properly
recorded. You are reviewing the financial statement reporting for the securities and have found a
newspaper clipping dated December 31 that indicates the price of the stock of Omni company
had dropped the day before because of the company\'s severe financial difficulties. While the
company is not expected to fail, the article states the earnings of the company have permanently
declined due to changes in the new-homes market. You do a quick check of the stock price on
that day and find that the stock closed at $8 per share. Panache owns 10,000 shares of Omni\'s
stock as an available-for-sale security. The original cost of the stock was $20 per share, and the
fair value at the last reporting date (September 30, 2016) was $15 per share. You have just begun
to write a memo to the president of the company, Mr. Cartwright, about this investment when he
stops by your office and says, \"I have a question for you.\" He says, \"As you know, we use a
special metal called tellurium in our cars. It takes 10 pounds for each car we build. I had a
feeling last summer that tellurium prices were going to go up in October, so Mr. Brown told me
he could lock the prices in by using a dirigible. Did he do that?\" \"It was probably a derivative,
Mr. Cartwright,\" you reply. \"Let me look through the files and see what I can find, and I\'ll get
back to you. I\'ll include my findings in the memo I\'m writing to you about another
investment.\" You locate a file labeled tellurium futures, and inside you find several documents.
The first one is a handwritten note dated August 31, 2015, that says: Agreed to tellurium futures
contract expiring December 31, 2015; agreement gives Panache the right to purchase 2,000
pounds of tellurium at a price of $500 per pound. Signed, C. Brown 8/31/2015. The second paper
is a schedule showing prices of tellurium: Date Price 8/31/2015 $500 9/30/2015 $530
10/31/2015 $550 The third document is an invoice for the purchase of 2,000 pounds of tellurium
on October 31 at $550 per pound. There is a note on the invoice in Ms. Brown\'s handwriting
that says: Settled futures contract today. C. Brown 10/31/2015. You know that tellurium
purchased in October would have been used to produce the 200 cars made in November. The
cars produced in November were sold in December for $15,000 each. The total cost to produce
the cars was $12,000 each. You are required to: Prepare all journal entries that should have been
recorded related to the futures contract, including any entries needed for the September 30, 2016,
financial statements; the purchase of the tellurium; and the sale of the cars in December. Create
the journal entries in an Excel spreadsheet. Write a 2-page memo to Mr. Cartwright that
includes: A discussion of the investment in Omni company stock and the requir.

How do you evaluate your own global mind set levelsSolutionAN.pdf
How do you evaluate your own global mind set levels?
Solution
ANSWER:
A global mindset is refers to a special trait of global leadership which is associated with
manager-employee relationship, trust, and organizational commitment. There are prime three
features of global mindset namely- intellectual capital, psychological capital and social capital.
While evaluating my own global mind set levels I have to consider all these features. Intellectual
capital is my ability to understand and process new information, which are helpful to learn about
people of different cultures and know how to respond. Psychological capital, is evaluating my
openness, cognitive flexibility and willingness to work with other cultures. Social capital is the
relationships network that I have with their colleagues from different cultures, and can help me
to act in a trustworthy manner and build relationship with others from different cultures. The
development of a global mindset that sub-includes cultural intelligence and global business
orientation will help me to think globally and swiftly act to maintain the competitiveness in
multicultural organizations and international markets. Keeping all these above points, I can
properly designed questionnaire survey can be of useful in global mindset evaluation for me as
well as others. My global mindset affects the cognitive capabilities and the decision-making
patterns, thus exerting significant influence on the strategic capabilities of firms as well as my
personal life..

Median
Solution
Data set B: Mean will be affected since we have outlier(720) in the data hence we know that
outlers are very much affected by mean . But no affect on the Median.
Getting StartedCreate a class called Lab8. Use the same setup for .pdf
Getting Started
Create a class called Lab8. Use the same setup for setting up your class and main method as you
did for the previous assignments. Be sure to name your file Lab8.java. Additionally, make
another file called Arrays.java. This file will be an object, so simply start it off by declaring an
Arrays class. You can copy the following skeleton and fill in the appropriate code below each of
the comments:
public class Arrays {
/ Instance Variables
// Constructors
// findMin 1
// findMax
// calcSum
// calcAverage
// toString
}
Task Overview
Your task for this lab is to create a class called Arrays with some array processing methods. This
class will maintain an array and the number of elements present in it. Additionally, methods will
be available to display the current min and max elements along with the average of all of them.
Finally, a toString() method will be available to cleanly display all the array elements. Finally,
you will write a simple driver class to test out the above Arrays class.
Part 1: Instance Variables for Arrays
The first thing to do for the Arrays class is to set up its instance variables. Declare the following
(private) instance variables:
• An int array called array ? this will be the array we will be writing methods for.
• An int called count - this represents the number of valid elements in the array.
Part 2:
Constructors for Arrays The Arrays class will have two constructors. The first constructor takes
the maximum size of the array as input as a parameter and initializes the array instance variable
appropriately. It also sets count to size. Finally, it will initialize all of the array elements to some
values between 0 and 10, inclusive. To create this constructor, follow these steps:
• Import java.util.Random to make use of the random number generator.
• Create a constructor with the following header: public Arrays(int size)
• Initialize your array variable and set its size to size (see the chart on page 252 for reference on
initializing arrays). Be very careful that you are setting the value of your array instance variable,
as opposed to creating a new variable called array.
• Set the value of the count variable to size because we will be populating the entire array.
• Copy the following code to the constructor in order to generate random values between 0 and
10, inclusive:
Random rand = new Random();
for (int i = 0; i < count; i++)
{
array[i] = (rand.nextInt(10));
}
Next, create another constructor with the following header: public Arrays(int[] arr). This
constructor will initialize the class by using the passed arr argument in order to fill its instance
variables. The following things need to be done inside of this constructor:
• Set the array variable equal to arr.
• Set the count variable equal to the length of the array.
Part 3: Displaying the Output findMin()
The first method of this class will search the array for the minimum element. Copy the following
code for the findMin method. Note how the count i.

Discuss what is SSH and the advantages and disadvantages of using it.pdf
Discuss what is SSH and the advantages and disadvantages of using it on your Linux
distribution.
Also discuss how to control ssh access and how you configure this service.
Solution
SSH is also known as Secure Socket Shell. It is a network protocol that provides administrators
with a secure way to access a remote computer.
For advantages of it, SSH is widely used by network administrators for managing systems and
applications remotely. It allows them to log in to another computer over a network, execute
commands and move files from one computer to another.
The biggest disadvantage would be people logging in as the computer\'s administrator over SSH
and this can be done by brute force for the password.
To limit ssh access to a linux machine based on originating IP address, edit /etc/hosts.allow:.
Describe the differences between the three major physical connection .pdf
Describe the differences between the three major physical connection mediums: twisted-pair
cable, coaxial cable, and fiber-optic cable.
Solution
Below is the Difference Between Fiber Optic Cable, Twisted Pair and coaxial Cable :
Twisted Pair Cables
Twisted pair cable consists of a pair of insulated wires twisted together, which is adapted in the
field of telecommunication for a long time. With the cable twisting together, it helps to reduce
noise from outside sources and crosstalk on multi-pair cables. Twisted pair cable works well on
transferring balanced differential signals, the merits of which are extremely valuable in wide
bandwidth and high fidelity system. Basically, twisted pair cable can be divided into two types:
unshielded twisted-pair (UTP) and shielded twisted-pair (STP). The former serves as the most
commonly used one with merely two insulated wires twisted together. Any data communication
cables and normal telephone cables belong to this category. However, shielded twisted pair
distinguishes itself from UTP in that it consists of a foil jacket which helps to prevent crosstalk
and noise from outside source. It is typically used to eliminate inductive and capacitive coupling,
so it can be applied between equipment, racks and buildings. With the advancement of
technology, the twisted pair cables are now being phased out by more technically developed and
reliable media.
Coaxial Cables
Coaxial cable acts as a high-frequency transmission cable which contains a single solid-copper
core. A coaxial cable has over 80 times the transmission capability of the twisted-pair. It is
commonly used to deliver television signals and to connect computers in a network as well, so
people may get more familiar with this kind of cable. Coaxial cable has always been the
mainstay of high speed communication and has also been applied to network with 10 gigabit
links data centers, because it is proved to be cost efficient for short links within 10 m and for
residential network. Besides, it features anti-jamming capability, stable transmission of data and
money saving. Coaxial cable is widely employed in feedlines connecting radio transmitters and
receivers, computer network connection, digital audio and television signals distribution.
Moreover, coaxial cable can effectively protect signals from being interfered by external
electromagnetic influence.
Fiber Optic Cables
Computing and data communications are fast-moving technologies. There comes a new
generation of transmission media—fiber optic cable. It refers to the complete assembly of fibers,
which contain one or more optical fibers that are used to transmit data. Each of the optical fiber
elements is individually coated by plastic layers and contained in a protective tube. Fiber optic
cable transmits data as pulses of light go through tiny tubes of glass, the transmission capacity of
which is 26,000 times higher than that of twisted-pair cable. When comparing with coaxial
cables, fiber optic cables ar.

C programming. Answer question only in C code Ninth Deletion with B.pdf
C programming. Answer question only in C code Ninth: Deletion with Binary Search Tree (20
points) In the ninth part, you will extend the binary search tree in the eighth part to support the
deletion of a node. The deletion of a node is slightly trickier compared to the search and insert in
the eighth The deletion is straightforward if the node to be deleted has only one child. You make
the parent of the node to be deleted point to that child. In this scenario, special attention must be
paid only when the node to be deleted is the root Deleting a node with two children requires
some more work. In this case, you must find the minimum element in the right subtree of the
node to be deleted. Then you insert that node in the place where the node to be deleted was. This
process needs to be repeated to delete the minimum node that was just moved In either case, if
the node to be deleted is the root, you must update the pointer to the root to point to the new root
node Input format: This program takes a file name as argument from the command line. The file
is either blank or contains successive lines of input. Each line contains a character, \'i or \'d\'
followed by a tab and an integer. For each line that starts with \'i\', your program should insert
that number in the binary search tree if it is not already there. If the line starts with a \'s, your
program should search for that value. If the line starts with a \'d\', your program should delete
that value from the tree output format: For each line in the input file, your program should print
the status/result of the operation. For insert and search, the output is the same as in the Eighth
Part: For an insert operation, the program should print either \"inserted\" with a single space
followed by a number the height of the inserted mode in the tree, or \"duplicate\" if the value is
already present in the tree. The height of the root node is 1. For a search, the program should
either print \"present\" followed by the height of the node, or absent\" based on the outcome of
the search. For a delete, the program should print \"success or \"fail\" based on the whether the
value was present or not. Again, as in the Eight Part, your program should print \"error\" (and
nothing else) if the file does not exist or for input lines with improper structure Example
Execution: Lets assume we have a file filel.txt with the following contents: i 5 i 3 i 4 i 1 i 6 i 2 s
1 d 3 s 2 Executing the program in the following fashion should produce the output shown
below:
Solution

Aside from the expansion of industrial capitalism, what factors affe.pdf
Aside from the expansion of industrial capitalism, what factors affected American development
during the late 19th centry? How important are those factors in comparison to capitalism’s
growth?
Solution
ANSWER:
During the late nineteenth Americans believed for the expansion of national borders in order to
keep the America running upright. Moreover, the Americans believed that the United States was
the most powerful of nations, and that they could take any land they pleased. The expansion of
American started after the Civil War. The war made substantial use of the telegraph and
railroads. Moreover there was a crucial expansion of railroads with a motive on combing the
Atlantic and Pacific coasts, with movement.
This growing population and an advanced transportation is one of the main causes of expansions
of America in late 19th century. Europeans with surplus wealth joined Americans in investing
the economic expansion of the nation. Also the farmers during this time required arable land for
livestock and crops which was unavailable due to overcrowding. Thus financial panics uprooted
them and sent them west for a new start. Furthermore, the American government also motivated
the citizens to move west, with the motive of acquisition of new territory from foreign powers.
The above discussed factors are different from the factors in capitalism’s growth. Capitalism is a
system in an economy where private entities own the factors of production namely
entrepreneurship, natural resources, capital goods and labor; and ensures that an economy will
produce the most desired products at an acceptable price. The owners of capital goods,
entrepreneurship and natural resources exercise control through companies..

Solution
Yates says that unions actually mean better pay, benefits, and slao working conditions for their
members and they indeed force employers to treat employees with dignity and respect; and at
their maximum best, they provide the workers to work in the society with utmost satisfaction on
the whole. Yates used simple language with suffiecient examples to tell that how unions popped
out to be helpful at certain troublesome instants on the whole. His arguments exactly carried on
to tell the importance of unions and he advises all the workers to join in the unions which would
be ultimately beneficial to them on the whole..

what is the relationship between information hiding as an attribute .pdf
what is the relationship between information hiding as an attribute of effective modularity and
the concept of module independence?
Solution
ans-
The concept of functional dependencies is a direct outgrowth of modularity and the concept of
abstraction and information hiding
Functional dependencies is acheived by developing modules with single minded function and an
\"aversion\" to excessive interaction with other module
independence is important because software with efffective modularity i.e independent modules
is easier to develop because fuction may be compartmentalized and interfaces are simplified.
indepent modules are easier to maintain because secondary effects caused by design and code
modification are limited ,error progression is reduced and reusable modules are possible .
fuctional independence is a key to good design is the key to software quality.
independence is assessed using in two qualitative criteria

What form of market efficiency do you think that the U. S. financial.pdf
What form of market efficiency do you think that the U. S. financial market have?
Solution
It is the semi strong form of market efficiency in the US financial market as it quickly absorbs
the publicly available information via news, articles or any other source apart from the
information drawn from its own historical data. Further, the presence of superior connectivity
and spreading of the information to the investors, bring semi-strong form of efficiency in the
market.
Strong form efficiency includes insider information that is prohibited even in the US financial
market by the regulatory agencies. So, there is no any strong form efficiency in the US financial
market..
What are the biggest threats to a network in terms of security and w.pdf
What are the biggest threats to a network in terms of security and why?
Describe what you would do to protect a network from attack, mention any appliances or
products you
can recommend.
Solution
Network security is the major part of a network that needs to be mentained as various important
information is being passed from the various systems.And is very vulnerable to attack.The
biggest threats are as follows:
1) Viruses and warms
The after-effects of viruses are so dangerous that they take second place. The vulnerability here
is the back doors viruses leave in their wake, or the chinks in the corporate armour that later
generations of code can exploit.
the worms that turn PCs into remote mail servers and send cascading volumes of e-mails that
cause denial of service attacks. These attacks are becoming more sophisticated.
2) Trozen Horses
Trojan is any malicious computer program which is used to hack into a computer by misleading
users of its true intent
3)Phishing:
Phishing, or identity theft, is most commonly targeted at bank customers but everybody should
be alert to it. The bank users receive an e-mail as if from the bank asking for their log-on and
password and, according to risk specialist company mi2g, less than half of 1% of customers
oblige, a significant figure if millions of e-mails are sent.
4) Password Attack
Password attacks are the classic way to gain access to a computer system is to find out the
password and log in. The growth of the Internet has created unlimited opportunity for these
intruders to steal secrets, tinker with Web sites, abscond with credit card information, or just
generally make mischief
5)Shared Computers
When computer are shared it create a LAN type network which shares all the various
information by the users and the informtio can easiy access by any one at that time.It is not
secure .
Security in NETWORK is a MYTH.
A denial of service attack might be thwarted if the security system recognises high levels of a
particular sort of traffic before they become so high the network falls over..
How to Break the cycle of negative Thoughts
We all have good and bad thoughts from time to time and situation to situation. We are bombarded daily with spiraling thoughts(both negative and positive) creating all-consuming feel , making us difficult to manage with associated suffering. Good thoughts are like our Mob Signal (Positive thought) amidst noise(negative thought) in the atmosphere. Negative thoughts like noise outweigh positive thoughts. These thoughts often create unwanted confusion, trouble, stress and frustration in our mind as well as chaos in our physical world. Negative thoughts are also known as “distorted thinking”.

How do you evaluate your own global mind set levelsSolutionAN.pdf
How do you evaluate your own global mind set levels?
Solution
ANSWER:
A global mindset is refers to a special trait of global leadership which is associated with
manager-employee relationship, trust, and organizational commitment. There are prime three
features of global mindset namely- intellectual capital, psychological capital and social capital.
While evaluating my own global mind set levels I have to consider all these features. Intellectual
capital is my ability to understand and process new information, which are helpful to learn about
people of different cultures and know how to respond. Psychological capital, is evaluating my
openness, cognitive flexibility and willingness to work with other cultures. Social capital is the
relationships network that I have with their colleagues from different cultures, and can help me
to act in a trustworthy manner and build relationship with others from different cultures. The
development of a global mindset that sub-includes cultural intelligence and global business
orientation will help me to think globally and swiftly act to maintain the competitiveness in
multicultural organizations and international markets. Keeping all these above points, I can
properly designed questionnaire survey can be of useful in global mindset evaluation for me as
well as others. My global mindset affects the cognitive capabilities and the decision-making
patterns, thus exerting significant influence on the strategic capabilities of firms as well as my
personal life..

Getting StartedCreate a class called Lab8. Use the same setup for .pdf
Getting Started
Create a class called Lab8. Use the same setup for setting up your class and main method as you
did for the previous assignments. Be sure to name your file Lab8.java. Additionally, make
another file called Arrays.java. This file will be an object, so simply start it off by declaring an
Arrays class. You can copy the following skeleton and fill in the appropriate code below each of
the comments:
public class Arrays {
/ Instance Variables
// Constructors
// findMin 1
// findMax
// calcSum
// calcAverage
// toString
}
Task Overview
Your task for this lab is to create a class called Arrays with some array processing methods. This
class will maintain an array and the number of elements present in it. Additionally, methods will
be available to display the current min and max elements along with the average of all of them.
Finally, a toString() method will be available to cleanly display all the array elements. Finally,
you will write a simple driver class to test out the above Arrays class.
Part 1: Instance Variables for Arrays
The first thing to do for the Arrays class is to set up its instance variables. Declare the following
(private) instance variables:
• An int array called array ? this will be the array we will be writing methods for.
• An int called count - this represents the number of valid elements in the array.
Part 2:
Constructors for Arrays The Arrays class will have two constructors. The first constructor takes
the maximum size of the array as input as a parameter and initializes the array instance variable
appropriately. It also sets count to size. Finally, it will initialize all of the array elements to some
values between 0 and 10, inclusive. To create this constructor, follow these steps:
• Import java.util.Random to make use of the random number generator.
• Create a constructor with the following header: public Arrays(int size)
• Initialize your array variable and set its size to size (see the chart on page 252 for reference on
initializing arrays). Be very careful that you are setting the value of your array instance variable,
as opposed to creating a new variable called array.
• Set the value of the count variable to size because we will be populating the entire array.
• Copy the following code to the constructor in order to generate random values between 0 and
10, inclusive:
Random rand = new Random();
for (int i = 0; i < count; i++)
{
array[i] = (rand.nextInt(10));
}
Next, create another constructor with the following header: public Arrays(int[] arr). This
constructor will initialize the class by using the passed arr argument in order to fill its instance
variables. The following things need to be done inside of this constructor:
• Set the array variable equal to arr.
• Set the count variable equal to the length of the array.
Part 3: Displaying the Output findMin()
The first method of this class will search the array for the minimum element. Copy the following
code for the findMin method. Note how the count i.

Discuss what is SSH and the advantages and disadvantages of using it.pdf
Discuss what is SSH and the advantages and disadvantages of using it on your Linux
distribution.
Also discuss how to control ssh access and how you configure this service.
Solution
SSH is also known as Secure Socket Shell. It is a network protocol that provides administrators
with a secure way to access a remote computer.
For advantages of it, SSH is widely used by network administrators for managing systems and
applications remotely. It allows them to log in to another computer over a network, execute
commands and move files from one computer to another.
The biggest disadvantage would be people logging in as the computer\'s administrator over SSH
and this can be done by brute force for the password.
To limit ssh access to a linux machine based on originating IP address, edit /etc/hosts.allow:.
Describe the differences between the three major physical connection .pdf
Describe the differences between the three major physical connection mediums: twisted-pair
cable, coaxial cable, and fiber-optic cable.
Solution
Below is the Difference Between Fiber Optic Cable, Twisted Pair and coaxial Cable :
Twisted Pair Cables
Twisted pair cable consists of a pair of insulated wires twisted together, which is adapted in the
field of telecommunication for a long time. With the cable twisting together, it helps to reduce
noise from outside sources and crosstalk on multi-pair cables. Twisted pair cable works well on
transferring balanced differential signals, the merits of which are extremely valuable in wide
bandwidth and high fidelity system. Basically, twisted pair cable can be divided into two types:
unshielded twisted-pair (UTP) and shielded twisted-pair (STP). The former serves as the most
commonly used one with merely two insulated wires twisted together. Any data communication
cables and normal telephone cables belong to this category. However, shielded twisted pair
distinguishes itself from UTP in that it consists of a foil jacket which helps to prevent crosstalk
and noise from outside source. It is typically used to eliminate inductive and capacitive coupling,
so it can be applied between equipment, racks and buildings. With the advancement of
technology, the twisted pair cables are now being phased out by more technically developed and
reliable media.
Coaxial Cables
Coaxial cable acts as a high-frequency transmission cable which contains a single solid-copper
core. A coaxial cable has over 80 times the transmission capability of the twisted-pair. It is
commonly used to deliver television signals and to connect computers in a network as well, so
people may get more familiar with this kind of cable. Coaxial cable has always been the
mainstay of high speed communication and has also been applied to network with 10 gigabit
links data centers, because it is proved to be cost efficient for short links within 10 m and for
residential network. Besides, it features anti-jamming capability, stable transmission of data and
money saving. Coaxial cable is widely employed in feedlines connecting radio transmitters and
receivers, computer network connection, digital audio and television signals distribution.
Moreover, coaxial cable can effectively protect signals from being interfered by external
electromagnetic influence.
Fiber Optic Cables
Computing and data communications are fast-moving technologies. There comes a new
generation of transmission media—fiber optic cable. It refers to the complete assembly of fibers,
which contain one or more optical fibers that are used to transmit data. Each of the optical fiber
elements is individually coated by plastic layers and contained in a protective tube. Fiber optic
cable transmits data as pulses of light go through tiny tubes of glass, the transmission capacity of
which is 26,000 times higher than that of twisted-pair cable. When comparing with coaxial
cables, fiber optic cables ar.

C programming. Answer question only in C code Ninth Deletion with B.pdf
C programming. Answer question only in C code Ninth: Deletion with Binary Search Tree (20
points) In the ninth part, you will extend the binary search tree in the eighth part to support the
deletion of a node. The deletion of a node is slightly trickier compared to the search and insert in
the eighth The deletion is straightforward if the node to be deleted has only one child. You make
the parent of the node to be deleted point to that child. In this scenario, special attention must be
paid only when the node to be deleted is the root Deleting a node with two children requires
some more work. In this case, you must find the minimum element in the right subtree of the
node to be deleted. Then you insert that node in the place where the node to be deleted was. This
process needs to be repeated to delete the minimum node that was just moved In either case, if
the node to be deleted is the root, you must update the pointer to the root to point to the new root
node Input format: This program takes a file name as argument from the command line. The file
is either blank or contains successive lines of input. Each line contains a character, \'i or \'d\'
followed by a tab and an integer. For each line that starts with \'i\', your program should insert
that number in the binary search tree if it is not already there. If the line starts with a \'s, your
program should search for that value. If the line starts with a \'d\', your program should delete
that value from the tree output format: For each line in the input file, your program should print
the status/result of the operation. For insert and search, the output is the same as in the Eighth
Part: For an insert operation, the program should print either \"inserted\" with a single space
followed by a number the height of the inserted mode in the tree, or \"duplicate\" if the value is
already present in the tree. The height of the root node is 1. For a search, the program should
either print \"present\" followed by the height of the node, or absent\" based on the outcome of
the search. For a delete, the program should print \"success or \"fail\" based on the whether the
value was present or not. Again, as in the Eight Part, your program should print \"error\" (and
nothing else) if the file does not exist or for input lines with improper structure Example
Execution: Lets assume we have a file filel.txt with the following contents: i 5 i 3 i 4 i 1 i 6 i 2 s
1 d 3 s 2 Executing the program in the following fashion should produce the output shown
below:
Solution
// C program to demonstrate delete operation in binary search tree
#include
#include
struct node
{
int key;
struct node *left, *right;
};
// A utility function to create a new BST node
struct node *newNode(int item)
{
struct node *temp = (struct node *)malloc(sizeof(struct node));
temp->key = item;
temp->left = temp->right = NULL;
return temp;
}
// A utility function to do inorder traversal of BST
void inorder(struct node *root)

Aside from the expansion of industrial capitalism, what factors affe.pdf
Aside from the expansion of industrial capitalism, what factors affected American development
during the late 19th centry? How important are those factors in comparison to capitalism’s
growth?
Solution
ANSWER:
During the late nineteenth Americans believed for the expansion of national borders in order to
keep the America running upright. Moreover, the Americans believed that the United States was
the most powerful of nations, and that they could take any land they pleased. The expansion of
American started after the Civil War. The war made substantial use of the telegraph and
railroads. Moreover there was a crucial expansion of railroads with a motive on combing the
Atlantic and Pacific coasts, with movement.
This growing population and an advanced transportation is one of the main causes of expansions
of America in late 19th century. Europeans with surplus wealth joined Americans in investing
the economic expansion of the nation. Also the farmers during this time required arable land for
livestock and crops which was unavailable due to overcrowding. Thus financial panics uprooted
them and sent them west for a new start. Furthermore, the American government also motivated
the citizens to move west, with the motive of acquisition of new territory from foreign powers.
The above discussed factors are different from the factors in capitalism’s growth. Capitalism is a
system in an economy where private entities own the factors of production namely
entrepreneurship, natural resources, capital goods and labor; and ensures that an economy will
produce the most desired products at an acceptable price. The owners of capital goods,
entrepreneurship and natural resources exercise control through companies..

what is the relationship between information hiding as an attribute .pdf
what is the relationship between information hiding as an attribute of effective modularity and
the concept of module independence?
Solution
ans-
The concept of functional dependencies is a direct outgrowth of modularity and the concept of
abstraction and information hiding
Functional dependencies is acheived by developing modules with single minded function and an
\"aversion\" to excessive interaction with other module
independence is important because software with efffective modularity i.e independent modules
is easier to develop because fuction may be compartmentalized and interfaces are simplified.
indepent modules are easier to maintain because secondary effects caused by design and code
modification are limited ,error progression is reduced and reusable modules are possible .
fuctional independence is a key to good design is the key to software quality.
independence is assessed using in two qualitative criteria
1.cohesion-
cohesion is an indication of relative fuction strength of a module , a cohesive module perfom a
single task ,requiring little interaction with the other components in other parts of the program .
2.coupling-
coupling is an indication of relative interdependence among module ,a coupling depends on
interface complexity between modules ,the point at which entry or reference is made to module
and what data passes across interface ..

It is the semi strong form of market efficiency in the US financial market as it quickly absorbs
the publicly available information via news, articles or any other source apart from the
information drawn from its own historical data. Further, the presence of superior connectivity
and spreading of the information to the investors, bring semi-strong form of efficiency in the
market.
Strong form efficiency includes insider information that is prohibited even in the US financial
market by the regulatory agencies. So, there is no any strong form efficiency in the US financial
market..
What are the biggest threats to a network in terms of security and w.pdf
What are the biggest threats to a network in terms of security and why?
Describe what you would do to protect a network from attack, mention any appliances or
products you
can recommend.
Solution
Network security is the major part of a network that needs to be mentained as various important
information is being passed from the various systems.And is very vulnerable to attack.The
biggest threats are as follows:
1) Viruses and warms
The after-effects of viruses are so dangerous that they take second place. The vulnerability here
is the back doors viruses leave in their wake, or the chinks in the corporate armour that later
generations of code can exploit.
the worms that turn PCs into remote mail servers and send cascading volumes of e-mails that
cause denial of service attacks. These attacks are becoming more sophisticated.
2) Trozen Horses
Trojan is any malicious computer program which is used to hack into a computer by misleading
users of its true intent
3)Phishing:
Phishing, or identity theft, is most commonly targeted at bank customers but everybody should
be alert to it. The bank users receive an e-mail as if from the bank asking for their log-on and
password and, according to risk specialist company mi2g, less than half of 1% of customers
oblige, a significant figure if millions of e-mails are sent.
4) Password Attack
Password attacks are the classic way to gain access to a computer system is to find out the
password and log in. The growth of the Internet has created unlimited opportunity for these
intruders to steal secrets, tinker with Web sites, abscond with credit card information, or just
generally make mischief
5)Shared Computers
When computer are shared it create a LAN type network which shares all the various
information by the users and the informtio can easiy access by any one at that time.It is not
secure .
Security in NETWORK is a MYTH.
A denial of service attack might be thwarted if the security system recognises high levels of a
particular sort of traffic before they become so high the network falls over..

How to Break the cycle of negative Thoughts
We all have good and bad thoughts from time to time and situation to situation. We are bombarded daily with spiraling thoughts(both negative and positive) creating all-consuming feel , making us difficult to manage with associated suffering. Good thoughts are like our Mob Signal (Positive thought) amidst noise(negative thought) in the atmosphere. Negative thoughts like noise outweigh positive thoughts. These thoughts often create unwanted confusion, trouble, stress and frustration in our mind as well as chaos in our physical world. Negative thoughts are also known as “distorted thinking”.

The Roman Empire A Historical Colossus.pdf
The Roman Empire, a vast and enduring power, stands as one of history's most remarkable civilizations, leaving an indelible imprint on the world. It emerged from the Roman Republic, transitioning into an imperial powerhouse under the leadership of Augustus Caesar in 27 BCE. This transformation marked the beginning of an era defined by unprecedented territorial expansion, architectural marvels, and profound cultural influence.
The empire's roots lie in the city of Rome, founded, according to legend, by Romulus in 753 BCE. Over centuries, Rome evolved from a small settlement to a formidable republic, characterized by a complex political system with elected officials and checks on power. However, internal strife, class conflicts, and military ambitions paved the way for the end of the Republic. Julius Caesar’s dictatorship and subsequent assassination in 44 BCE created a power vacuum, leading to a civil war. Octavian, later Augustus, emerged victorious, heralding the Roman Empire’s birth.
Under Augustus, the empire experienced the Pax Romana, a 200-year period of relative peace and stability. Augustus reformed the military, established efficient administrative systems, and initiated grand construction projects. The empire's borders expanded, encompassing territories from Britain to Egypt and from Spain to the Euphrates. Roman legions, renowned for their discipline and engineering prowess, secured and maintained these vast territories, building roads, fortifications, and cities that facilitated control and integration.
The Roman Empire’s society was hierarchical, with a rigid class system. At the top were the patricians, wealthy elites who held significant political power. Below them were the plebeians, free citizens with limited political influence, and the vast numbers of slaves who formed the backbone of the economy. The family unit was central, governed by the paterfamilias, the male head who held absolute authority.
Culturally, the Romans were eclectic, absorbing and adapting elements from the civilizations they encountered, particularly the Greeks. Roman art, literature, and philosophy reflected this synthesis, creating a rich cultural tapestry. Latin, the Roman language, became the lingua franca of the Western world, influencing numerous modern languages.
Roman architecture and engineering achievements were monumental. They perfected the arch, vault, and dome, constructing enduring structures like the Colosseum, Pantheon, and aqueducts. These engineering marvels not only showcased Roman ingenuity but also served practical purposes, from public entertainment to water supply.

Suppose public-key cryptography is used to encrypt the communications.pdf
- 1. Suppose public-key cryptography is used to encrypt the communications between Alice and Bob. Alice's public key is eA, private key is dA; Bob's public key is private key is de. Now Bob wants to send a message m to Alice. Describe which keys should be used to encrypt the message and decrypt the ciphertext. Solution Answer:- Bob's message is encrypted using eA and when Alice receives message from Bob it is decrypted using dB Explanation:- *In public key cryptography, each user has two keys and each user publishes one key (public key) keeping another key private (private key). *Consider two users A and B, if A wants to send a message to B , A's message is encrypted using B's public key. When B receives message from A , it is decrypted using B's private key.
