(TCO 1) Who are the users of managerial accounting information- How do.docx
(TCO 1) Who are the users of managerial accounting information? How does their use of accounting information differ from the users of financial accounting information?
Solution
Answer: Accounting information helps users to make better financial decisions. Users of financial information may be both internal and external to the organization.
Internal users (Primary Users) of accounting information include the following:
External users (Secondary Users) of accounting information include the following:
They use financial statements in order to satisfy some of their different needs for information. These needs include the following:
(a) Investors. The providers of risk capital and their advisers are concerned with the risk inherent in, and return provided by, their investments. They need information to help them determine whether they should buy, hold or sell. Shareholders are also interested in information which enables them to assess the ability of the enterprise to pay dividends.
(b) Employees. Employees and their representative groups are interested in information about the stability and profitability of their employers. They are also interested in information which enables them to assess the ability of the enterprise to provide remuneration, retirement benefits and employment opportunities.
(c) Lenders. Lenders are interested in information that enables them to determine whether their loans, and the interest attaching to them, will be paid when due.
(d) Suppliers and other trade creditors. Suppliers and other creditors are interested in information that enables them to determine whether amounts owing to them will be paid when due. Trade creditors are likely to be interested in an enterprise over a shorter period than lenders unless they are dependent upon the continuation of the enterprise as a major customer.
(e) Customers. Customers have an interest in information about the continuance of an enterprise, especially when they have a long-term involvement with, or are dependent on, the enterprise.
(f) Governments and their agencies. Governments and their agencies are interested in the allocation of resources and, therefore, the activities of enterprises. They also require information in order to regulate the activities of enterprises, determine taxation policies and as the basis for national income and similar statistics.
(g) Public. Enterprises affect members of the public in a variety of ways. For example, enterprises may make a substantial contribution to the local economy in many ways including the number of people they employ and their patronage of local suppliers. Financial statements may assist the public by providing information about the trends and recent developments in the prosperity of the enterprise and the range of its activities.

( Subsequent events ) Green, CPA, is auditing the financial statements of Taylor Corporation for the year ended December 31, 20X1. Green plans to complete the fieldwork and sign the auditor\'s report about May 10, 20X2. Green is concerned about events and transactions occurring after December 31, 20X1, that may affect the 20X1 financial statements.
Required
Solution
a. What are the general types of subsequent events that require Green\'s consideration and evaluation?
Answer:
There are two types of subsequent event:
2. events that provide evidence with respect to conditions that did not exist at the date of the balance sheet being reported on but arose subsequent to that date.
b. What are the auditing procedures Green should consider performing to gather evidence concerning subsequent events?
The auditor should perform audit procedures designed to obtain sufficient appropriate audit evidence that all events up to the dat of the auditor\'s report that may require adjustment of, or disclosure in, the financial statements have been identified.
CONDITIONS THAT EXISTED AT THE DATE OF THE BALANCE SHEET AND EVENTS OCCURRING UP TO THE DATE O THE AUDITOR\'S REPORT:
The auditor is required to perform following audit procedues:
FACTS DISCOVERED AFTER THE DATE OF THE AUDITOR\'S REPORT BUT BEFORE THE DATE THE FINANCIAL STATEMENTS ARE ISSUED:
The auditor does not have any responsibility to perform audit procedures or make inquiry regarding the financial statements after the date of the auditor\'s report. During the period from the date of the auditor\'s report to the date the financial statements are issued, the responsibility to inform the auditor of facts which may affect the financial statements rest with the management,

(Reliability engineering) Make a list of six population stereotypical responses
Solution
a stereotype is a thought that can be adopted about specific types of individuals or certain ways of doing things.These thoughts or beliefs may or may not accurately reflect reality.
Stereotype content refers to the attributes that people think characterize a group. Studies of stereotype content examine what people think of others, rather than the reasons and mechanisms involved in stereotyping.
Cognitive functions:
Stereotypes can help make sense of the world. They are a form of categorization that helps to simplify and systematize information. Thus, information is more easily identified, recalled, predicted, and reacted to.Stereotypes are categories of objects or people. Between stereotypes, objects or people are as different from each other as possible.
Explanation purposes:
As mentioned previously, stereotypes can be used to explain social events. Jews were stereotyped as being evil and yearning for world domination to match the anti-Semitic ‘facts’ as presented in The Protocols of the Elders of Zion.
Justification purposes:
People create stereotypes of an outgroup to justify the actions that their ingroup has committed towards that outgroup.
Intergroup differentiation:
An assumption is that people want their ingroup to have a positive image relative to outgroups, and so people want to differentiate their ingroup from relevant outgroups in a desirable way. If an outgroup does not affect the ingroup’s image, then from an image preservation point of view, there is no point for the ingroup to be positively distinct from that outgroup
Social functions: self-categorization:
People will change their stereotype of their ingroups and outgroups to suit the context they are in.[3][23] People are likely to self-stereotype their ingroup as homogenous in an intergroup context, and they are less likely to do so in an intragroup context where the need to emphasise their group membership is not as great. Stereotypes can emphasise a person’s group membership in two steps: First, stereotypes emphasise the person’s similarities with ingroup members on relevant dimensions, and also the person’s differences from outgroup members on relevant dimensions. Second, the more the stereotypes emphasise within-group similarities and between-group differences, the more salient the person’s social identity will become, and the more depersonalised that person will be.
Social functions: social influence and consensus:
Stereotypes are an indicator of ingroup consensus. When there are intragroup disagreements over stereotypes of the ingroup or outrgroups, ingroup members will take collective action to prevent other ingroup members from diverging from each othe

Investigate the importance of effective change leadership in relation to an organization’s adoption of social media initiatives
In current scenario we have high importance of effective change leadership in relation to an organization’s adoption of social media initiatives. Social media is used now a days by the corporate leaders as well as by managers for effective internal communication as well as better engagement with customers. Social
media such as facebook, twitter, various types of blogs are now a days used in various business practices for better communication
suggest two (2) ethical issues that a CIO may encounter when implementing social media initiatives. Propose (1) strategy for addressing each identified issue
1. With the implementing of social media it may happen the employess may spend more hours on social media for their own personal business rather than for company business
Solution: Some new company policies should be created, having clear cut guide lines of using social networking and media websites.
2. With the implementing of social media , it may happen that employess start harshing each other on social media sites and posting negative comments against each other.
Solution: Social Media tracking for each employee should be done on time to time.

-- I have two classes One is Carnivore and the other is Herbivore- Eac.docx
// I have two classes One is Carnivore and the other is Herbivore. Each of them is having its own shape and move function across the screen. Now i want to put them togehter in the following Environment Class so that i can see them moving across the screen simultaneously. But this function is giving me a blank screen if i try to add both of those classes. If i add just one class, it works. What am i doing wrong in this Java coding? import javax.swing.JFrame; import javax.swing.JPanel; public class Environment { public static Environment earth; public Environment() { Carnivore s = new Carnivore(); Herbivore h = new Herbivore(); JFrame f = new JFrame(); JPanel pane = new JPanel(); pane.add(s); pane.add(h); f.add(pane); f.setVisible(true); f.setSize(600,400); f.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE); f.setTitle(\"The Jungle Life\"); } }
Solution
Modified your code... you should have main method, then we have to create and panel and add this panel to frame
import javax.swing.JFrame;
import javax.swing.JPanel;
public class Environment
{
//frame instance declared
public JFrame f;
//constructor
public Environment(){
prepareGUI();
}
//main method
public static void main(String args[]){
Environment earth = new Environment();
earth.showEnvironment();
}
//preparing frame in this method
public void prepareGUI()
{
f = new JFrame();
f.setVisible(true);
f.setSize(600,400);
f.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
f.setTitle(\"The Jungle Life\");
}
//then finally adding this frame to panel
public void showEnvironment(){
//creating carnivore and herbivore objects
Carnivore s = new Carnivore();
Herbivore h = new Herbivore();

-- I have two classes One is Carnivore and the other is Herbivore- Eac.docx
// I have two classes One is Carnivore and the other is Herbivore. Each of them is having its own shape and move function across the screen. Now i want to put them togehter in the following Environment Class so that i can see them moving across the screen simultaneously. But this function is giving me a blank screen if i try to add both of those classes. If i add just one class, it works. What am i doing wrong in this Java coding? import javax.swing.JFrame; import javax.swing.JPanel; public class Environment { public static Environment earth; public Environment() { Carnivore s = new Carnivore(); Herbivore h = new Herbivore(); JFrame f = new JFrame(); JPanel pane = new JPanel(); pane.add(s); pane.add(h); f.add(pane); f.setVisible(true); f.setSize(600,400); f.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE); f.setTitle(\"The Jungle Life\"); } }
Solution
Modified your code... you should have main method, then we have to create and panel and add this panel to frame
import javax.swing.JFrame;
import javax.swing.JPanel;
public class Environment
{
//frame instance declared
public JFrame f;
//constructor
public Environment(){
prepareGUI();
}
//main method
public static void main(String args[]){
Environment earth = new Environment();
earth.showEnvironment();
}
//preparing frame in this method
public void prepareGUI()
{
f = new JFrame();
f.setVisible(true);
f.setSize(600,400);
f.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
f.setTitle(\"The Jungle Life\");
}
//then finally adding this frame to panel
public void showEnvironment(){
//creating carnivore and herbivore objects
Carnivore s = new Carnivore();
Herbivore h = new Herbivore();
JPanel panel = new JPanel();
panel.add(s);

- Answer the following questions about acids 1- What is the phase of a.docx
. Answer the following questions about acids 1. What is the phase of all acids? 2. What is the smallest particle to represent an acid? 3. What kind of bond holds acids together? Defend your answer
Solution
Ans. #1. All acids are present in aqueous phase .
# An acid (Arrhenius – Bronsted Lowry acid) is a chemical species that donates a H + .
To donate an H + , the acid must be in contact with a H + -acceptor. For most of the acids that we encounter, water acts as a medium or acceptor. Therefore, all acids are present in aqueous phase so that acid molecule can donate an H + -ion to the medium.
#2. H + ion is the smallest ion present in an acid.
An acid has a general formula of AH – where A is an element (say, Cl) or a group (NO 3 ). In all case, H + ion or H-atom constitutes the smallest particle of an acid because there is no other element in the periodic table smaller than an H-atom.
#3. Because of greater difference in the electronegativity of the acidic H-atom and A, the acid molecule has relatively positive charge center at the H-atom, and a negative charge center at the A atom group. So, the bond between H + and A atom/group is relatively polar covalent bond .
# The acid molecules may be held together by intermolecular H-bonds (HNO 3 , H 2 SO 4 , HClO 4 , etc. oxoacids), or dipole-dipole attractions (HCl, HCN, HBr, etc.) or other forces depending on the nature of the acid molecule.
# Hydrogen bond is a weak attractive force between a highly electronegative atoms (O, N, F) and a H-atoms linked to such atoms.
The criteria for H-bonds formation is that there must be -
I. A highly electronegative atom ( F, N, O -atom), and
II. A H-atoms linked to such atoms (F, N, O).

Solution
On August 13, 1942, the Manhattan Engineer District was founded to direct and coordinate a series of research projects known as the Manhattan project under the direction of engineer Leslic Groves.
On December 2, 1942, Enrico Fermi and his collaborators achieved the first self-sustained and controlled chain fission reaction, only four years after it was discovered that a uranium atom bombarded with neutrons could be split (or fission) generating a large amount of energy and several neutrons that could continue the process by impacting other uranium atoms.
July 16, 1945 the first nuclear bomb is detonated in the desert of the Alamo Gordo, in New Mexico (United States). Call the Trinity test.
On August 6, 1945, when World War II was about to end, a uranium bomb called \"Little Boy\" was launched by the mythical plane Enola Gay on Hiroshima (Japan) and caused more than 100,000 deaths, besides destroying the city. The order was given by Harry Truman, president of the United States.
On August 9, 1945, a plutonium bomb called \"Fat Man\" was dropped on Nagasaki, with results comparable to that released 3 days earlier.
Ivy Mike, the first hydrogen bomb (thermonuclear fusion bomb) and that was developed by the Americans. It was detonated in an atoll in the Marshall Islands at 7:15 (local time) on November 1, 1952, or at 7:15 pm on October 31 (world time).
On July 26, 1986, the Chernobyl nuclear power plant accident occurred. It was the biggest nuclear catastrophe in history. The explosion took place in the fourth block of the Chernobyl nuclear power station, located only 120 kilometers from the capital of Ukraine - Kiev, near the border with Belarus.
As a result of the earthquake and tsunami that occurred on March 11, 2011 in Japan, the Fukushima nuclear power plant was seriously damaged. This number 1 plant of Tokyo Electric Power in Fukushima (known as Daiichi) is located about 270 kilometers northeast of Tokyo, has six boiling light water reactors, operates since 1971 and had permission to continue active until the year 2021.

CPM stands for Central Processing Unit. It\'s also called as processor . It is considered a s brain of a computer. Is is responsible for performing all functions and processes. It is made up of various transistors and each transistor receive a set of inputs and produces output.The CPU mainly interacts with main memory,referring to it for both instructions and data. The main components of a CPU are listed below:
a)Control Unit
This is reponsible for fetching the instructions from main memory and the executon of these instructions.
It uses electrical signals to instruct the whole computer system for carrying out or executing,already stored program instructions.Its name clearly shows that it controls and co-ordinates computer components.It extracts instructions from memory and decodes and executes them.In fact it regulates the flow of information through the processor. It acts as a bridge between arithmetic unit and memory.
b)Registers
Registers are temporary storage areas which are responsible for holding the data that is to be processed.They store the instructions and data in a processor.This data is further used by Control Unit.There are some registers that are set aside for specific tasks, these generally include a program counter, stack, and flags.
c)Combinational logic
This is responsible for performing all arithmetic and logical operations.
It performs arithmetic calculations like as addition, subtraction, multiplication and division as well as comparisons.The unit can compare numbers, letters, or special characters.There can be more than one Arithmetic logic unit in a CPU, and these ALUs can also be used for the purpose of maintaining timers that help run the computer.
d)Main Memory
e)Input/Output:Input sends data to a CPU and output makes the processed information available for the other devices to consume.

(Audit evidence) The third GAAS of field work requires that the auditor obtain sufficient competent audit evidence to afford a reasonable basis for an opinion regarding the financial statements under audit. In considering what constitutes sufficient competent evidential matter, a distinction should be made between underlying accounting records and other information available to the auditor.
Required
Discuss the nature of audit evidence to be considered by the auditor in terms of the underlying accounting records, other corroborating information available to the auditor, and the methods by which the auditor tests or gathers competent evidence.
State the presumptions that can be made about the validity of audit evidence with respect to (1) other information and (2) underlying accounting records.
AICPA (adapted)
Solution
Audit evidence
the information available the auditor in arriving at the conclusions in which the audit opinion is based and includes the information contained in the accounting records underlying the financial statement and other informations.the auditor should obtain the audit evidence by testing the accounting records , by analysis and by review. the accounting records some times cannot give the full evidence.the sufficient and approprate evidence is based on the quality of the evidence.some of the SAAs guidliness are given below
1.the evidence are obtained by directly by the auditor. it is more relaible than indirectly obtained by the individual.
2. evidence are more relaible isobtained from the uotside of the entity
3.evidence is more reliable when it is in documentary form.
accounting records
the accounting records involving the evidence of the internal control over financial reporting.it also check reports such as cheks, invoices,contracts,etc..
the important audit procedures are
1.to understand client and industry : priliminary planning and risk analysis
2.access the risk of meterial misstatement : understand and test internal controls and system processing

What is the Big Bang-SolutionBig Bang is a theory which talks ababo th.docx
What is the Big Bang?
Solution
Big Bang is a theory which talks ababo the formation of universe. This phenomenon took place 13.8 billion years back.
It was first proposed by Georges Lemaitre. He said that a very long time ago, the universe started as just a single point. It stretched and expanded to get as big as it is now, and that it could keep on stretching.
When the universe began, it was just hot, tiny particles mixed with light and energy. It was nothing like what we see now. As everything expanded and took up more space, it cooled down.
The tiny particles grouped together. They formed atoms. Then those atoms grouped together. Over lots of time, atoms came together to form stars and galaxies.
The first stars created bigger atoms and groups of atoms called molecules. That led to more stars being born. At the same time, galaxies were crashing and grouping together. As new stars were being born and dying, then things like asteroids, comets, planets, and black holes formed.

What is the concept of sustainable income- Please describe it in your.docx
What is the concept of sustainable income? Please describe it in your own words. Can you give an example of what this number may look like by using the income statement of a real-life company?
Solution
Sustainable Income is income from ordinary operational activities which is of a recurring nature. That is the stake holders expectation about continuity of income reported in the future years. The Financial Income statement may contain both transactions pertains to regular operating activities as well as non-recurring and non operational items. If non operational items are of a recurring nature, it may also be taken in to consideration for determining sustainable income. Infact one of the limitation for an Income Statement prepared as per GAAP, is the volatility due to high profit in one period compared to another period. Investors or other persons interested in the financials of a company is more interested in sustainability of the earnings of the company, i.e whether the company will be able to generate the same level income under similar operating conditions.
Examples of items which is normally excluded from the calculation of sustainable income are:
Gain on sale of a major fixed assets
Compensation or grants received from authorities for initial set up or loss incurred under specified conditions
Loss of assets due to theft,fire etc.
Expenses which will bring benefits for multiple years like major advertisment/ marketing expenses
Research and development expenses which brings long time benefits

What is the backbone for the Internet? Briefly describe how the Internet works.
Solution
An internet backbone refers to one of the
principal data routes betweeen large, strategically
interconnected networks and core routers on the internet
they provide a consistent way for \"internet service provider\"(isp)
to keep and maintain data online with security.
Internet:
it is a globalsystem of interconnected physicl computer networks such as
lan\'s,wan\'s and man\'s. in simple terms network is a network\'s of million\'s of
public,private connected with the help of widely available internet working devices.
Working of internet:
The client initates the process and send request for particular internet service
The n/w devices such as modem and ethernet card process the signal so that it can be sent over the local loop carrier or the signal carriers.
Loop connects the loaction of user to isp point of presence. it accepts connection from users authentic connetcions.the signal are then transfered to isp regional network consisting of interconnected routers in different cities served by isp.
If the packet is supposed to reach the host, whichh is directly served by the isp, then it is delivered to the host.otherwise the packet is sent to isp backbone operator
if the packet recived by the backbone is supposed to reach a server then the packet is forwarded to the nearest router.

What is the difference between the creation and the exploitation of te.docx
What is the difference between the creation and the exploitation of technology?
Solution
Technology in the earliest days was about the discovery of fire and then from there man\'s curiosity lead to various discoveries and inventions. We travelled a long way from discovering fire to the birth of industrial revolution in the 19th century. When man first created technology , it was meant for reducing the complexities and hardships of doing some work and also for saving time. Invention of new things meant rediscovering the capabiltiy of a man in achieving things.
Main aspects of technology are human activities that help in creating new products,the goods and services required to enable such services and important criteria is the knowledge and skills required for this.
And now we have advanced in this field of technology so much that we simply don\'t seem to stop anywhere in our paths to achieve something. The burning desire to discover more things has always been the top most priority for us. And this hunger for new things lead to exloitation of technology in many ways. Technology was created to be used for easing out some of our hardships.But now we seem to be using technology for even the most silliest reasons. Over the period of time,we have simply become lazy in doing things because of technology.We are exploiting technology by using it for wrong reasons like doing household chores,for obtaining information illegally,a company using technology for bringing down another company and etc. All such things have made us ponder over the question as to whether technology provd to be a bane or a boon.

What is the difference between information found on the internet and other sources of information?
Solution
Difference between information found on the internet and other sources of information are
Information from other Sources such as printing is more expensive and difficult to accomplish whereas information form Internet Sources is not so much expensive and also available free of cost.
Information found on Internet does not have a print equivalent, and hence, has low or no quality standards for publication whereas information found on other sources such as journal or newspaper articles can be found in both print and digital format and has quality standards for publication.
In Internet Sources dates of publication and timeliness of information are questionable on the Internet. Dates listed on Web sites could be the date posted, date updated, or a date may not be listed at all. whereas information from Other Sources, date of publication, publisher, author, and editor are always clearly listed in print publications.

(70 pts) Nuclear History Identify the event in nuclear history that occurred on each of the following dates: August 13, 1942 July 16, 1945 August 9, 1945 April 26, 1986 December 2, 1942 August 6, 1945 October 31, 1952 March 11, 2011
Solution
On August 13, 1942, the Manhattan Engineer District was founded to direct and coordinate a series of research projects known as the Manhattan project under the direction of engineer Leslic Groves.
On December 2, 1942, Enrico Fermi and his collaborators achieved the first self-sustained and controlled chain fission reaction, only four years after it was discovered that a uranium atom bombarded with neutrons could be split (or fission) generating a large amount of energy and several neutrons that could continue the process by impacting other uranium atoms.
July 16, 1945 the first nuclear bomb is detonated in the desert of the Alamo Gordo, in New Mexico (United States). Call the Trinity test.
On August 6, 1945, when World War II was about to end, a uranium bomb called \"Little Boy\" was launched by the mythical plane Enola Gay on Hiroshima (Japan) and caused more than 100,000 deaths, besides destroying the city. The order was given by Harry Truman, president of the United States.
On August 9, 1945, a plutonium bomb called \"Fat Man\" was dropped on Nagasaki, with results comparable to that released 3 days earlier.
Ivy Mike, the first hydrogen bomb (thermonuclear fusion bomb) and that was developed by the Americans. It was detonated in an atoll in the Marshall Islands at 7:15 (local time) on November 1, 1952, or at 7:15 pm on October 31 (world time).
On July 26, 1986, the Chernobyl nuclear power plant accident occurred. It was the biggest nuclear catastrophe in history. The explosion took place in the fourth block of the Chernobyl nuclear power station, located only 120 kilometers from the capital of Ukraine - Kiev, near the border with Belarus.
As a result of the earthquake and tsunami that occurred on March 11, 2011 in Japan, the Fukushima nuclear power plant was seriously damaged. This number 1 plant of Tokyo Electric Power in Fukushima (known as Daiichi) is located about 270 kilometers northeast of Tokyo, has six boiling light water reactors, operates since 1971 and had permission to continue active until the year 2021.

Solution
CPM stands for Central Processing Unit. It\'s also called as processor . It is considered a s brain of a computer. Is is responsible for performing all functions and processes. It is made up of various transistors and each transistor receive a set of inputs and produces output.The CPU mainly interacts with main memory,referring to it for both instructions and data. The main components of a CPU are listed below:
a)Control Unit
This is reponsible for fetching the instructions from main memory and the executon of these instructions.
It uses electrical signals to instruct the whole computer system for carrying out or executing,already stored program instructions.Its name clearly shows that it controls and co-ordinates computer components.It extracts instructions from memory and decodes and executes them.In fact it regulates the flow of information through the processor. It acts as a bridge between arithmetic unit and memory.
b)Registers
Registers are temporary storage areas which are responsible for holding the data that is to be processed.They store the instructions and data in a processor.This data is further used by Control Unit.There are some registers that are set aside for specific tasks, these generally include a program counter, stack, and flags.
c)Combinational logic
This is responsible for performing all arithmetic and logical operations.
It performs arithmetic calculations like as addition, subtraction, multiplication and division as well as comparisons.The unit can compare numbers, letters, or special characters.There can be more than one Arithmetic logic unit in a CPU, and these ALUs can also be used for the purpose of maintaining timers that help run the computer.
d)Main Memory
e)Input/Output:Input sends data to a CPU and output makes the processed information available for the other devices to consume.

(Audit evidence) The third GAAS of field work requires that the audito.docx
(Audit evidence) The third GAAS of field work requires that the auditor obtain sufficient competent audit evidence to afford a reasonable basis for an opinion regarding the financial statements under audit. In considering what constitutes sufficient competent evidential matter, a distinction should be made between underlying accounting records and other information available to the auditor.
Required
Discuss the nature of audit evidence to be considered by the auditor in terms of the underlying accounting records, other corroborating information available to the auditor, and the methods by which the auditor tests or gathers competent evidence.
State the presumptions that can be made about the validity of audit evidence with respect to (1) other information and (2) underlying accounting records.
AICPA (adapted)
Solution
Audit evidence
the information available the auditor in arriving at the conclusions in which the audit opinion is based and includes the information contained in the accounting records underlying the financial statement and other informations.the auditor should obtain the audit evidence by testing the accounting records , by analysis and by review. the accounting records some times cannot give the full evidence.the sufficient and approprate evidence is based on the quality of the evidence.some of the SAAs guidliness are given below
1.the evidence are obtained by directly by the auditor. it is more relaible than indirectly obtained by the individual.
2. evidence are more relaible isobtained from the uotside of the entity
3.evidence is more reliable when it is in documentary form.
accounting records
the accounting records involving the evidence of the internal control over financial reporting.it also check reports such as cheks, invoices,contracts,etc..
the important audit procedures are
1.to understand client and industry : priliminary planning and risk analysis
2.access the risk of meterial misstatement : understand and test internal controls and system processing
3.to gather evidence related to account balance and transactions.

What is the Big Bang-SolutionBig Bang is a theory which talks ababo th.docx
What is the Big Bang?
Solution
Big Bang is a theory which talks ababo the formation of universe. This phenomenon took place 13.8 billion years back.
It was first proposed by Georges Lemaitre. He said that a very long time ago, the universe started as just a single point. It stretched and expanded to get as big as it is now, and that it could keep on stretching.
When the universe began, it was just hot, tiny particles mixed with light and energy. It was nothing like what we see now. As everything expanded and took up more space, it cooled down.
The tiny particles grouped together. They formed atoms. Then those atoms grouped together. Over lots of time, atoms came together to form stars and galaxies.
The first stars created bigger atoms and groups of atoms called molecules. That led to more stars being born. At the same time, galaxies were crashing and grouping together. As new stars were being born and dying, then things like asteroids, comets, planets, and black holes formed.

What is the concept of sustainable income- Please describe it in your.docx
What is the concept of sustainable income? Please describe it in your own words. Can you give an example of what this number may look like by using the income statement of a real-life company?
Solution
Sustainable Income is income from ordinary operational activities which is of a recurring nature. That is the stake holders expectation about continuity of income reported in the future years. The Financial Income statement may contain both transactions pertains to regular operating activities as well as non-recurring and non operational items. If non operational items are of a recurring nature, it may also be taken in to consideration for determining sustainable income. Infact one of the limitation for an Income Statement prepared as per GAAP, is the volatility due to high profit in one period compared to another period. Investors or other persons interested in the financials of a company is more interested in sustainability of the earnings of the company, i.e whether the company will be able to generate the same level income under similar operating conditions.
Examples of items which is normally excluded from the calculation of sustainable income are:
Gain on sale of a major fixed assets
Compensation or grants received from authorities for initial set up or loss incurred under specified conditions
Loss of assets due to theft,fire etc.
Expenses which will bring benefits for multiple years like major advertisment/ marketing expenses
Research and development expenses which brings long time benefits

What is the backbone for the Internet? Briefly describe how the Internet works.
Solution
An internet backbone refers to one of the
principal data routes betweeen large, strategically
interconnected networks and core routers on the internet
they provide a consistent way for \"internet service provider\"(isp)
to keep and maintain data online with security.
Internet:
it is a globalsystem of interconnected physicl computer networks such as
lan\'s,wan\'s and man\'s. in simple terms network is a network\'s of million\'s of
public,private connected with the help of widely available internet working devices.
Working of internet:
The client initates the process and send request for particular internet service
The n/w devices such as modem and ethernet card process the signal so that it can be sent over the local loop carrier or the signal carriers.
Loop connects the loaction of user to isp point of presence. it accepts connection from users authentic connetcions.the signal are then transfered to isp regional network consisting of interconnected routers in different cities served by isp.
If the packet is supposed to reach the host, whichh is directly served by the isp, then it is delivered to the host.otherwise the packet is sent to isp backbone operator
if the packet recived by the backbone is supposed to reach a server then the packet is forwarded to the nearest router.

What is the meaning of the keyword this- Explain why it is valid only.docx
What is the meaning of the keyword this? Explain why it is valid only in the implementation of a member function
Solution
This Keyword : It refers to the current object.Used to invoke local and global variables and member functions like constructors.
Here is the usage of this keyword in java.
In java class  we are having member functions .we can implement those member functions using this keyword only.Here member functions are nothing but methods in java programming.
Let us consider sample java program to implementation of a member function using this keyword.Here in below java program we are taking member functions as constructors.
Program:
import java.io.*;
class Thiskeyword
{
public int i;
public Thiskeyword() // member function of Thiskeyword
{
this(20); //must be the first statement , calling the constructor
System.out.println(\"\ \\t THIS() Constructor is called\");
i=10;
System.out.println(\"\ \\t the value of i= \"+i);
}
public Thiskeyword(int i) //member function with parameters
{
System.out.println(\"\ \\t THIS(int j) constructor is called\");
this.i=i; //pointing to the current class member
System.out.println(\"\ \\t the value of i= \"+i);
}
}
class This // main class
{
public static void main(String a[])throws IOException
{
System.out.println(\"\ \\t start of main()\");
Thiskeyword t=new Thiskeyword();
System.out.println(\"\ \\t end of main()\");
}
}
Output:
start of main()
THIS(int j) constructor is called
the value of i=20
THIS() constructor is called
the value of i=10
end of main()

What is the difference between the creation and the exploitation of te.docx
What is the difference between the creation and the exploitation of technology?
Solution
Technology in the earliest days was about the discovery of fire and then from there man\'s curiosity lead to various discoveries and inventions. We travelled a long way from discovering fire to the birth of industrial revolution in the 19th century. When man first created technology , it was meant for reducing the complexities and hardships of doing some work and also for saving time. Invention of new things meant rediscovering the capabiltiy of a man in achieving things.
Main aspects of technology are human activities that help in creating new products,the goods and services required to enable such services and important criteria is the knowledge and skills required for this.
And now we have advanced in this field of technology so much that we simply don\'t seem to stop anywhere in our paths to achieve something. The burning desire to discover more things has always been the top most priority for us. And this hunger for new things lead to exloitation of technology in many ways. Technology was created to be used for easing out some of our hardships.But now we seem to be using technology for even the most silliest reasons. Over the period of time,we have simply become lazy in doing things because of technology.We are exploiting technology by using it for wrong reasons like doing household chores,for obtaining information illegally,a company using technology for bringing down another company and etc. All such things have made us ponder over the question as to whether technology provd to be a bane or a boon.

What is the difference between information found on the internet and o.docx
What is the difference between information found on the internet and other sources of information?
Solution
Difference between information found on the internet and other sources of information are
Information from other Sources such as printing is more expensive and difficult to accomplish whereas information form Internet Sources is not so much expensive and also available free of cost.
Information found on Internet does not have a print equivalent, and hence, has low or no quality standards for publication whereas information found on other sources such as journal or newspaper articles can be found in both print and digital format and has quality standards for publication.
In Internet Sources dates of publication and timeliness of information are questionable on the Internet. Dates listed on Web sites could be the date posted, date updated, or a date may not be listed at all. whereas information from Other Sources, date of publication, publisher, author, and editor are always clearly listed in print publications.

2024.06.01 Introducing a competency framework for languag learning materials ...
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.
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.
