Solution
Part 1:
Due to much lower attenuation and interference, provides long distance, Fiber optic signals are
stronger.These are much thinner and lighter than metal wires.Data can be transmitted digitally.It
has less susceptible to interference.
Part 2:
An amplifier can not discriminate between the intended signal and noise,it amplifies equally
everything fed into it.A repeater does not amplify the signal.It regenerates the signal.When it
receives a weakened or corrupted signal,it creates a copy,bit for bit at the original strength. A
repeater is a regenerator.
Using the large number of amplifiers over a long, lossy link inevitablyincreases the noise and
decreases the signal to noise levels.A repeater is usually a receiver followed by a regenerating
logic and transmitter.In this case regeneration receives the digital signals and retimes it to
remove jitter and then retransmits it with minimal baseband noise.
Part 4:
Graphical User Interface uses graphics along with a keyboard and mouse,to provide an easy to
use interface to a program.It provides windows,pulldown menus,buttons,scrollbars,iconic
images,wizards and other icons and the mouse to enable the users to interact with the operating

Solution
1) An Operating System (OS) is an interface between a computer user and computer hardware.
An operating system is a software which performs all the basic tasks like file management,
memory management, process management, handling input and output, and controlling
peripheral devices such as disk drives and printers.
An interface is a shared boundary across which two separate components of a computer system
exchange information. The exchange can be between software, computer hardware, peripheral
devices, humans and combinations of these. Some computer hardware devices such as a
touchscreen can both send and receive data through the interface, while others such as a mouse
or microphone may only provide an interface to send data to a given system.
Based on the user interface, there are two types of operating systems.
2)
An Operating System provides services to both the users and to the programs.
It provides programs an environment to execute.
It provides users the services to execute the programs in a convenient manner.
Following are a few common services provided by an operating system
Program execution
I/O operations
File System manipulation

3)An abstraction layer or abstraction level is a way of hiding the implementation details of a
particular set of functionality, allowing the separation of concerns to facilitate interoperability
and platform independence. Software models that use layers of abstractioninclude the OSI 7-
layer model for computer network protocols, the OpenGL graphics drawing library, and the byte
stream input/output (I/O) model originated from Unix and adopted by MS-DOS, Linux, and most
other modern operating systems.
4) communication services is important to the long-term success of any business. In the early

OpenFlow:
A Radical New Idea in Networking
An open standard that enables software-defined networking
Thomas A. Limoncelli
Computer networks have historically evolved box by box, with individual network elements
occupying specific ecological niches as routers, switches, load balancers, NATs (network address
translations), or firewalls. Software-defined networking proposes to overturn that ecology, turning
the network as a whole into a platform and the individual network elements into programmable
entities. The apps running on the network platform can optimize traffic flows to take the shortest
path, just as the current distributed protocols do, but they can also optimize the network to
maximize link utilization, create different reachability domains for different users, or make device
mobility seamless.
OpenFlow, an open standard that enables software-defined networking in IP networks, is a new
network technology that will enable many new applications and new ways of managing networks.
Here are three real, though somewhat fictionalized, applications:
EXAMPLE 1: BANDWIDTH MANAGEMENT. A typical wide area network has 30 percent utilization;
it must “reserve” bandwidth for “burst” times. Using OpenFlow, however, a system was developed
in which internal application systems (consumers) that need bulk data transfer could use the
spare bandwidth. Typical uses include daily replication of datasets, database backups, and the
bulk transmission of logs. Consumers register the source, destination, and quantity of data to
be transferred with a central service. The service does various calculations and sends the results
to the routers so they know how to forward this bulk data when links are otherwise unused.

NETWORKING
It is a supportive system of sharing information and services among individuals and groups having a common interest.
A local-area network (LAN) is basically defined as two or more computers connected by a structured wire system for the purpose of sharing resources and files. In this chapter we will explain the various ‘structured wire systems’ that the Network Engineer will deal with during the course of their job. Wireless LANs are becoming more and more popular, but even these devices rely on some amount of physical wires in most cases.
REQUIREMENTS
Network Adapter
A computer needs a network adapter to connect to a network. It converts computer data into electronic signals. It listens for silence on the network cable and applies the data to it when it has an opportunity. The network access element of its job is called Media Access Control, or MAC. The physical address of every computer on a network is called its MAC address. The MAC address is the network adapter's serial number. Most computers are shipped with the network adapter integrated into the motherboard. However, early PCs didn't include this function and computer owners had to buy it separately and fit it into an expansion slot on the motherboard. These were called "network cards" because they were sold on a separate card. Although network adapters are now integrated, the name network card is still used. The wireless equivalent is called a Wireless Network Interface Controller.
Network Medium
Wired networks need cable. The most common form of cable used in networks is called the "Unshielded Twisted Pair." In PC shops, it is generally just referred to as "network cable" or "Ethernet cable." Ethernet is the most widely implemented set of standards for the physical properties of networks. UTP is so closely identified with Ethernet that it is often given that name. Other cable types used for networks are twin-axial, Shielded Twisted Pair and single-mode and multi-mode fiber optic cable. Wireless networks don't need cable; they send data on radio waves generated by the WNIC.
Cable Connectors
In wired networks, the most common form of connector is the RJ45. Every computer with networking capabilities has an RJ45 port. This is sometimes called a "network port" or an "Ethernet port." The RJ45 plug looks like a slightly larger telephone plug and connects the Unshielded Twisted Pair or the Shielded Twisted Pair cable.
Power Supply
Both wired and wireless networks need a power supply. A wireless network uses the current to generate radio waves. A cabled network sends data interpreted as an electronic pulse.
Hub/Switch/Router
In wired networks, one computer cannot connect to many others without some form of splitter. A hub is little more than a splitter. It repeats any signals coming into one of its ports out onto all its other ports. A cable leads from each port to one computer. A switch ...
A network consists of two or more computers that are linked together in order to share
the resources, such as printers, exchange files among computers, with the help of electronic
communications. The computers on a network may be linked by cables, telephone lines,
radio waves, satellites, or infrared light beams etc.

The terminology employed in factory automation is often confusing in.pdffashionbigchennai
The terminology employed in factory automation is often confusing in part because the names
are so similar and in part because the sub areas do indeed overlap. Carefully distinguish among
CIM , CAD , CAE , CAM and CAPP indicating any overlaps.
Solution
CIM(computer integrated manufacturing):
It is the approach of using computers for controling the entire production process.
This integration allows individual processes to exchange information with each other and
initiate actions among them.
It simply means the fully use of computer controlled machines and fully automation system in
manufacturing products.
CAD(computer aided design):
It is a software and is used by architects, engineers or artists for the creation of precision
drawing for technical overview. it is also helpful in the creation of 2D or 3D models.
CAE(computer aided engineering):
Is a process of solving problems related to engineering through the help of interactive graphical
software.It can be graphical or mathematical or modeling.
CAM(computer aided manufacturing):
is the software for the controlling of maching tools or to assist all the process for the
manufacturing of the machine.
CIPP(computer aided process planning):
Is the use of technology for the process and planning of a part or product in manufacturing.
CAPP is the process in between CAD and CAM. It provides the planning for the process for
producing a specific part.

CIM provides the internal logic and that is used while organizing the computers or the programs
and the information that flows among them.
Computer-aided manufacturing moto is to use the computer software to control machine tools
and related machinery(or machine parts) in the manufacturing process.
It is not technically or logically considered a system for engineering software programs, but
rather than for hardware solution.But on the other side computer aided engineering
involves the processes the software work, like the analysis or simulation part of the actual work
done..
The probability that A hits a target is 14 and the probability that.pdffashionbigchennai
The probability that A hits a target is 1/4 and the probability that B hits a target 1/3.
(a) If each fires twice, what is the probability that the target will be hit at least once?
(b) If each fire once and the target is hit only once, what is the probability that A hit the target?
Solution
probability that A hits a target = 1/4
probability that B hits a target = 1/3
a) after hitting twice, probability that the target will be hit at least once = 1 - probability that the
target is not hit at all
probability that the target is not hit at all = Probability that A does not hit the target the first time
* Probability that B does not hit the target the first time * Probability that A does not hit the
target the second time * Probability that B does not hit the target the second time
= (1 - 1/4) * (1 - 1/3) * (1 - 1/4) * (1 - 1/3)
= 3/4 * 2/3 * 3/4 * 2/3
= 1/4
after hitting twice, probability that the target will be hit at least once = 1 - 1/4 = 3/4
------------------------------------------
b)If each fire once and the target is hit only once, the probability that A hit the target =
probability that A hit the target * probability that B missed + probability that A hit the target *
probability that B hit the target
= 1/4 * (1 - 1/3) + 1/4 * 1/3
= 1/4 * 2/3 + 1/4 * 1/3
= 1/4.
Step 2 Formulate a HypothesisFormulate a hypothesis by making an .pdffashionbigchennai
Step 2: Formulate a Hypothesis
Formulate a hypothesis by making an explicit statement about the cause of the common cold
based on the observations and generalizations you made in Step 1.
based on the 3 things below
HypothesisObservation 1: Common cold is caused by bacterial or viral infection and transmitted
from one person to other through droplets from infected person. The person infected with
common cold show protect his nose or mouth with steril mask, which covers mouth and nose. If
nose or mouth is not covered by mask, droplets can transmit common cold to many people in
surrounding environment.
Observation 2: Common cold is widely transmitted very easily, if a person infected with
common cold and he sneezes in public places which is having high population, several thousands
of droplets can be transported through air at onetime, when person sneezes, so avoid moving in
public places when common cold is rampant in specific area.
Observation 3: Doctors who examine the persons suffering with common cold should be careful,
the physician should use antibiotics or vaccines to prevent common cold infection.
Solution
The hypothesis is this statement:
Common cold is a viral infectious disease which can be transmistted from one person to another
on sneezing.It can be prevented by taking antibiotics and vaccines by the physicians while
check-up..

magnitude of change of velocity with respect to time always represent accleration |a|, and its
value can be +/-|a|.
Reaction StatisticsBackgroundWhen collecting experimental data f.pdffashionbigchennai
Reaction Statistics
Background
When collecting experimental data from chemical reactions, it’s often useful to generate
statistics based on the data. One experimental measure is the reaction rate in moles per second,
representing the amount of product formed per unit time. If we have a set of these reaction rates
collected in a data file, we can calculate summary statistical information, such as the minimum
and maximum values, the arithmetic mean, variance, and standard deviation.
Finding the minimum and maximum are straightforward: we scan through all the data, and keep
track of the smallest and largest values encountered. The arithmetic mean (or average) is defined
as:
m = (X1+X2+…+Xn)/n
where n is the number of reaction rates, and xi represents one experimental reaction rate. Once
you have the arithmetic mean, the variance can be calculated as the mean of the squares of the
deviations from the mean:
v= ((Xn-m)^2+(X2 – m^2) + …+(Xn-m)^2)/n
where n is the number of reaction rates, xi represents one experimental reaction rate, and m is the
arithmetic mean of the reaction rates. Once you have the variance, you can calculate the
standarddeviation as:
s = sqrt(v)
Assignment
You will develop a C program that reads data from an input text file containing chemical
reaction rates (in moles per second), and computes the minimum, maximum, arithmetic mean,
variance, and standard deviation for that set of data. Your instructor will provide input text files,
which will each contain a series of double values, each on a line of its own within the file. Your
program will read one of these input files into an array of doubles (i.e., it will populate the array
using the data values from the file). Your program will then calculate statistics using that array of
doubles, and will write the results out to a separate output text file.
The goals of this assignment are to provide you with experience reading and writing text data
files, provide you with experience passing an array into a function, and give you more
experience organizing your program into separate C functions.
When defining your C functions, you may either:
Define the functions before they are used by any other functions, OR
Place function prototypes near the top of your code (after all #include directives), and then define
the functions in any order.
Part 1 – Opening Files and Reading Data
Create a new Visual Studio Win32 Console project named reactionstats. Create a new C source
file named project4.c within that project. At the top of the source file, #define
_CRT_SECURE_NO_WARNINGS, and then include stdio.h, math.h, stdlib.h, stdbool.h, and
float.h.
Inside your main function, define the following:
A one-dimensional array of 600 doubles. They do not need to be initialized to anything at this
stage.
An integer variable to hold the number of elements in the array, initialized using the approach
demonstrated in class, using sizeof.
A FILE pointer variable, which will refer to the input data text file..
Please explain in detaile the European debt crisisSolutionIn 2.pdffashionbigchennai
Please explain in detaile the European debt crisis
Solution
In 2007, EU economies, on the surface, seemed to be doing relatively well – with positive
economic growth and low inflation. Public debt was often high, but (apart from Greece) it
appeared to be manageable assuming a positive trend in economic growth.
However, the global credit crunch changed many things.
EU Bond Yields
Uncompetitiveness
Eurozone countries with debt problems are also generally uncompetitive with a higher inflation
rate and higher labour costs. This means there is less demand for their exports, higher current
account deficit and lower economic growth. (The UK became uncompetitive, but being outside
the Euro, the Pound could depreciate 20% restoring competitiveness.
Poor Prospects for Growth
People have been selling Greek and Italian bonds for two reasons. Firstly because of high
structural debt, but also because of very poor prospects for growth. Countries facing debt crisis
have to cut spending and implement austerity budgets. This causes lower growth, higher
unemployment and lower tax revenues. However, they have nothing to stimulate economic
growth.
Individual Cases
Greece’s Case
In early 2010 these difficult developments reflected in rising spreads on sovereign bond yields
between the affected peripheral member states of Greece, Ireland, Portugal and Spain, and most
notably Germany. The Greek yield diverged in early 2010 with Greece needing eurozone
assistance by May 2010. Greece received two bailouts from the EU over the following five years
during which the country adopted EU-mandated austerity measures to cut costs while
experiencing a further economic recession as well as social unrest. In June 2015 Greece, with
divided political and fiscal leadership and a continued recession, was facing a sovereign default.
However, on July 5, 2015 the Greek people voted against further EU austerity measures, with a
possibility of Greece leaving the European Monetary Union entirely. The withdrawal of a nation
from the EMU is unprecedented, and the speculated effects on Greece\'s economy if the currency
is returned to the drachma range from total economic collapse to a surprise recovery.
Ireland Case
Ireland followed Greece in requiring a bailout in November 2010, with Portugal next in May
2011. Italy and Spain were also vulnerable, with Spain requiring official assistance in June 2012
along with Cyprus. By 2014, Ireland, Portugal and Spain, due to various fiscal reforms, domestic
austerity measures and other unique economic factors, all successfully exited their bailout
programs requiring no further assistance. The road to full economic recovery is still underway.
Cyprus, too, reported a slow but steady ongoing recovery, averting further financial crisis thus
far.

Mary is an excellent waitress. In the restaurant, she can easily hand.pdffashionbigchennai
Mary is an excellent waitress. In the restaurant, she can easily handle 8 tables at a time without
getting overloaded/overworked. During a normal day the restaurant has an an average of 4 tables
to serve at a time. What is the probability Mary will be overworked in a given day? (Hint: Find
the probability there are more than 8 tables occupied)
Solution
This is a Poisson distribution with random variable X= no of tables Mary handles at a time
having a Poisson distribution with mena value = 4
P(X>8) = 0.0214
Prob for Mary overworking is 0.0214.
List three characteristics that influence the rate of simple diffusi.pdffashionbigchennai
List three characteristics that influence the rate of simple diffusion of small molecules.
Solution
Answer= Three characteristics that influence the rate of simple diffusion of small molecules
1] Particle size = Rate of diffusion is inversaly proportional to particle size
Since the heat of environment is the energy source for diffusion the smaller particles moves at a
faster rate than larger paricles at a given temperature
2] temperature = Rate of diffusion is directly proportional to temperature
As temperature increses rate of diffusion also increases
At high temp. particles move faster because more energy is available to diffuse them
3] Concentration difference = rate of increses as conc. difference increases
The substance diffusing between 2 areas exibits a conc. diffference as the particle diffuse from
one side of the wall to other side
4] particle distance = rate of diffusion is directly proportional to particle distance
it takes longer for a particle to diffuse when it is further away than it does for a particle that is
closer to the point of diffusion.
Its all worked out, but Im still very confused by the steps .pdffashionbigchennai
It\'s all worked out, but I\'m still very confused by the steps they took to get each part. Like why
multiply everything by (x^2 + 9) and then in the next step, how did they end up with those
answers? I\'m just very confused.
Solution
they just multiplide (x^2 + 9) for simpification
LIKE EXAMPLE
eq 2+3=5
if we multify both sides with 2
(2+3)2=5*2
10=10
equality not changed ,,,like we use this in mathematics
after solving eq they got X parameters and they cheked in original eq.

Is the world overpopulated? What are the arguments for the notion that the world is
overpopulated? What are some alternative approaches to this topic?
Solution
The human popualtion has been growing ever since the evolution of mankind. Overpopulation is
a condition when the population exceeds the carrying capacity of the environment. There is
continuous increase in the birth rate and a significant decrease in the mortality rate. This results
in increase in population at an alarming rate. The population of the world is predicted to keep on
rising 2050. The sources and resources are being exhausted. This would lead to environment\'s
inability to support life, reduced quality of life..

Identify the following Level of caudal end of subarachnoid space E.pdffashionbigchennai
Identify the following: Level of caudal end of subarachnoid space Epidural, subarachnoid
spaces Level of caudal end of spinal cord
Solution
Answer:-
Level of caudal end of Subarachnoid space is lower border S-2 Vertebra.
Epidural- Basically epidural space is define as the outermost part of the spinal canal.it is also
called as the epidural cavity. this space lying outside th edura meter. Dura meter enclsoed by the
subarachnoid space. it contains a lumphatics spinal nerve roots and network of internal vertebral
venous plexuses.level is L1 & L2.
Level of caudal end of spinal cord. - The Spinal cord can be defined as the long , thin tubular
bundles of nervous tissue and it supports cells and it run in vertebral column. the caudal end of
spianl cord is generaly cone shaped it is also called as the conus medullaris. and its ends at S2
level..
Operation “Blue Star” is the only event in the history of Independent India where the state went into war with its own people. Even after about 40 years it is not clear if it was culmination of states anger over people of the region, a political game of power or start of dictatorial chapter in the democratic setup.
The people of Punjab felt alienated from main stream due to denial of their just demands during a long democratic struggle since independence. As it happen all over the word, it led to militant struggle with great loss of lives of military, police and civilian personnel. Killing of Indira Gandhi and massacre of innocent Sikhs in Delhi and other India cities was also associated with this movement.
2024.06.01 Introducing a competency framework for languag learning materials ...Sandy Millin
http://sandymillin.wordpress.com/iateflwebinar2024
Published classroom materials form the basis of syllabuses, drive teacher professional development, and have a potentially huge influence on learners, teachers and education systems. All teachers also create their own materials, whether a few sentences on a blackboard, a highly-structured fully-realised online course, or anything in between. Despite this, the knowledge and skills needed to create effective language learning materials are rarely part of teacher training, and are mostly learnt by trial and error.
Knowledge and skills frameworks, generally called competency frameworks, for ELT teachers, trainers and managers have existed for a few years now. However, until I created one for my MA dissertation, there wasn’t one drawing together what we need to know and do to be able to effectively produce language learning materials.
This webinar will introduce you to my framework, highlighting the key competencies I identified from my research. It will also show how anybody involved in language teaching (any language, not just English!), teacher training, managing schools or developing language learning materials can benefit from using the framework.
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”.

Part 7: Explain how frequency division multiplexing can be used to carry two or more
independent information streams on one communication medium.
Part 8: A modern CPU has a bit that can place the CPU in the system state or the application
state. Briefly describe the difference between "system state" and "application state."
Part 9: What does it mean to "mount" or "unmount" a storage device? Explain why
unmounting a device is necessary in the Windows operating system.
Part 10: Explain what it means to bootstrap a computer. In your answer, describe the steps
executed by the hardware and software in bootstrapping a computer that is initially turned off.
Solution
Part 1:
Due to much lower attenuation and interference, provides long distance, Fiber optic signals are
stronger.These are much thinner and lighter than metal wires.Data can be transmitted digitally.It
has less susceptible to interference.
Part 2:
An amplifier can not discriminate between the intended signal and noise,it amplifies equally
everything fed into it.A repeater does not amplify the signal.It regenerates the signal.When it
receives a weakened or corrupted signal,it creates a copy,bit for bit at the original strength. A
repeater is a regenerator.
Using the large number of amplifiers over a long, lossy link inevitablyincreases the noise and
2. decreases the signal to noise levels.A repeater is usually a receiver followed by a regenerating
logic and transmitter.In this case regeneration receives the digital signals and retimes it to
remove jitter and then retransmits it with minimal baseband noise.
Part 4:
Graphical User Interface uses graphics along with a keyboard and mouse,to provide an easy to
use interface to a program.It provides windows,pulldown menus,buttons,scrollbars,iconic
images,wizards and other icons and the mouse to enable the users to interact with the operating
system. users easy to control,manipulate and toggle through multiple programs and folders at
same time. Using Command Line Interface, it do not offer the same ease and ability to view
multiple things at once on one screen.
part 9:
The mount command mounts a storage device or file system, making it accssible and attaching it
to an existing directory structure.The unmount command unmounts a mounted file
system,incoming the file system,informing the system to complete any pending read or write
operations and safely detaching it.
Part 10:
Bootstraping is the process of loading the basic software into the memory of a computer after
power on or general reset. generally the operating system which will then take care of loading
other software as needed. In computers pressing a bootstrap button caused a hardwired program
to read a bootstrap program from an input unit.
