What is entropy- What is its significance for engineering devices and.docx
What is entropy? What is its significance for engineering devices and processes?
Solution
Entropy is a thermodynamic quantity representing the unavailability of a system\'s thermal energy for conversion into mechanical work, often interpreted as the degree of disorder or randomness in the system. The entropy of a substance is real physical quantity and is a definite function of the state of the body like pressure, temperature, volume of internal energy.
Significance- the significance of entropy revolves around the stability of a system/reaction. the higher the entropy, the more unstable the system/reaction. from the third law of thermodynamics we know that the entropy of a crystalline solid is zero at the absolute temperature (0 K). thus this is the most stable form of a substance. An increase in entropy implies a transition from on ordered to a less ordered state of affair.

What is Contingent Liabilities-SolutionContingent liabilities are thos.docx
What is Contingent Liabilities?
Solution
Contingent liabilities are those liabilities which are not liabilities as of now.
In future they may become liabilities. They are called contingent because they are not real.
Example: A bank shows all bank guarantees it has issued as contingent liabilities in its balance sheet. Reason: those bank guarantees may be invoked and may actually become liability in some unknown date in future.
Contingent liabilities are mentioned in balance sheet and annual report. There is a solid reason for the same. Suppose any contingent liability becomes a real liability in future then the stake holders in the company should not get surprised by sudden expense by the company.
Investors need to be informed of possible liabilities in future.

What is black box testing?
Solution
Black Box Testing:-
Black box testing refers to the testing of an application or software, it is actually used to test the functionality of the particular software without actually connecting the software to the actual peers,which it will use when it will actually start working.
So in other words we can say that is a dummy kind of testing done before launching the Software or the Application to make sure that it is working up to the mark.
It is also used to test different stages of the software while it is being build like unit, integration, system and acceptance,that is each virtual layer of testing can be done before the Software or the Application is Released.

What is an ETL plan that Ralph Kimball identifies from the 34 Subsystems that emphasize the most important within an organization.
Solution
The Extract-Transform-Load (ETL) system, that Ralph Kimball identifies from the 34 subsytems that emphasize the most important within an organization, is often estimated to consume 70 percent of the time and effort of building a data warehouse. But there hasn\'t been enough careful thinking about just why the ETL system is so complex and resource intensive.I think Everyone understands the three letters: You get the data out of its original source location (E), you do something to it (T), and then you load it (L) into a final set of tables for the users to query.The Ralph Kimball Group has been exposed to hundreds of successful data warehouses. Careful study of these successes has revealed a set of extract, transformation, and load (ETL) best practices.

Bit stuffing is a provider for Error Handling when Transfer Layer instead of Physical Layer in Control Area Network (CAN).A Controller Area Network (CAN bus) is a vehicle bus standard designed to allow microcontrollers and devices to communicate with each other in applications without a host computer. It is a message-based protocol, designed originally for multiplex electrical wiring within automobiles, but is also used in many other contexts.
It serves two purposes
In CAN bit Synchronization happens with an edge. So inserting an edge after 5 consecutive homogeneous bits ensures synchronization of all nodes. When the receiver is receiving homogeneous bits it will not understand whether it is reading the bit. so to avoid resulting Bit error Bit Stuffing is used.

What is a reasons for using layered protocols- What is one possible di.docx
What is a reasons for using layered protocols?
What is one possible disadvantage of using layered protocols?
Solution
Reasons for using Layered protocols:
1. Layering of protocols provides well-defined interfaces between the layers, so that a change in one layer does not affect an adjacent layer.
2. The protocols of a network are highly complicated and designing them in layers make their implementation more feasible.
Possible disadvantage of using Layered Protocol:
Each layer potentially puts overhead both in terms of information stored in protocol headers and processing time.

What is a single entry accounting system-Solution Single entry acco.docx
What is a single entry accounting system?
Solution
Single entry accounting system is considered as an incomplete system of recording financial transactions. Single entry system maintains only accounts of debtors, creditors and cash book Single entry accounting system is not based on concept of duality and thus is not self balancing. Chances of error are high. Single entry accounting system us generally used by small businesses as there are less formalities, simle to use and less expensive as compared to double emtry system. Single entry system requires less expertise. Single entry system is not preffered as it does not provide data for efficient planning to management, Less likely to detect threats and frauds and thus overall control suffers.

What is a false positive and how could it be used to hide a real attac.docx
What is a false positive and how could it be used to hide a real attack?
Solution
False positives are alerts generated by an IDS because it thinks it has detected a valid attack against a monitored system,but the attack really is not valid.False Positives are problems because they create alert noise that can hide a real attack,and then can send you a wild goos chases for attacks that never relly happened.
A False positive occurs when an IDS generates an alert on either
Network traffic that looks like an attack to the IDS,but isnot an attack.
A real attack that attack doesnot applyto the system being monitored.
A false negative is a real attack that was missed by the IDS, and therefore not alerted on.An IDS might miss an attack because the attack is not one it recognizes,becuse the IDS overwhelmed or because the attacker has successfully used a method of evading the IDS.

What impact does font selection have on readability-SolutionFont selec.docx
What impact does font selection have on readability?
Solution
Font selection plays a vital role in the readability. With different sizes and types of fonts we differentiate between headings, sub headings and the content of the paragraph.
We can even differentiate between the definition, explanation and example of a particular content in particular context.
For comfortable reading, we must always choose simple font like Times, Times New Roman,Calibri etc.
Fonts can also be used to display the content in artistic way. Usually these font types will be artistic and attractive look and feel but very complex when it comes to the point of readability.
In this manner font selection has various impact on readability.some are very simple and soothing which provide ease of readability and some are very complex it terms of readability.

What if Source One were to argue that it was merely an agent and was o.docx
What if Source One were to argue that it was merely an agent and was only responsible for gathering information... could Source One claim that its client is a principle, and therefore Source One is not responsible for the information request made by the client?
Solution
The attorney-client privilege has become one of the most complex
and therefore, litigated privileges.
1 This is due, in significant part, to the difficulties created by the concept of confidentiality.
2 From the creation and preservation of the privilege, to the development of the
facts to prove the legitimacy of the claim, the requirement of
confidentiality
3 has created time-consuming and costly responsibilities
for both litigants and judges.
4 In addition, confidentiality has been interpreted as imposing a superfluous secrecy requirement that has
generated conflicting decisions and practices.

What function does feedback play in the work of the manager and how do.docx
What function does “feedback” play in the work of the manager and how does accounting help the managers in this regard? Explain using examples to support your discussion.
Solution
Manager create value for employees in two ways. They remind employees of their value to the company. An employee gets motivation from manager\'s attitude and approach. Manager encourage employee feedback on any issue and let employees know that their opinions are taken seriously. Manager acts as the liaison between the executing staff and the employees.They create a dynamic workplace where employee feel that their opinions have vale to the company. This inspire employees to discover ways that are efficient to do their job.
Accouting help management in preparing financial data management, analysis and advice, financial report preparation, ensuring that all reporting deadlines are met.

What effect would the contamination by the following impurities have on the melting point of benzoic acid?
a. sand
b. benzoin
c. broken glass
d. pieces of insoluble cork
e. water
f. acetylsalicylic acid
Solution
There would be no effect on melting point of benzene of
Sand
Broken glass
And pieces of insoluble cork as they can no way interact chemically.
In case of benzoin and water, due to significant hydrogen bonding, melting point of benzene increases
For the case of acetylsalicylic acid, it does not increase because the acid hardly interact and form bond due to its large size and stearic hindrance.

What does wave-particle duality of light mean- What are some of the ev.docx
Wave-particle duality of light refers to light behaving as both a particle and wave depending on the situation. The photoelectric effect provides evidence for light's particle nature by ejecting electrons from metal when photons with sufficient energy strike. Young's double slit experiment supports light's wave nature through the interference of coherent waves which increases light intensity, demonstrating its wave-like properties.

What are some of the I-O hardware aspects (related to programming)- I.docx
- 1. What are some of the I/O hardware aspects (related to programming)? I/O devices can be divided into two categories block devices (that store information in a fixed-size block) and character devices (that deliver or accept a stream of characters) I/O units typically consist of a mechanical component and an electronic component; the electronic component is called the device controller each controller has a few registers that are used for communicating with the CPU - the operating system can write to those registers to command the device a Direct Memory Access (DMA) controller can be used to request data from an I/O controller instead of the CPU i and ii ii, iii, and iv iii and iv all of the above (i, ii, iii, and iv) Solution Last one is the answer all of the above (i,ii,iii,iv) Thank You!
