  1. a) Inferior Good and Normal Good
  2. b) Income Effect and Substitution Effect
  3. c) Shift in Supply Curve and Movement along Supply Curve.
  4. d) Elastic and Inelastic Demand

 

Answer:a) Inferior Good and Normal Good

Goods are classified in various types but to be specific, there are three types of goods which are known as Superior Goods, Normal Goods and Inferior Goods. Here, we will discuss about the major aspects that makes Inferior Good different from Normal Good.

 

Normal Goods-These goods are classified as Pulses and Spices and therefore it increases the demand when

 

 

 

 

  1. b) Income Effect and Substitution Effect

 

The Substitution Effect:The principal component clarifying expansion in consumption when price falls down is known as the substitution impact. The substitution impact means the substitution of one item for another resultfrom an adjustment in their relative cost.

 

Example: A lower cost of good X, with the costs of different products staying unchanged, will automatically increase

 

 

 

  1. c) Shift in Supply Curve and Movement along Supply Curve.

 

Supply curve Movement happens because of the demand curveshift. Supply curve shift causes the demand curve movement.

 

A movement along the supply curve is only an adjustment in cost and the relating amount requested at that cost. A movem

 

 

  1. d) Elastic and Inelastic Demand

 

Elastic demand implies that the sum or quantity of a specific item changes in substantial measure when the cost of the item changes, especially when the rate of the progress in the quantity of the item is being demanded is more prominent

 

 

Question.2. Differentiate between the Laws of returns to variable proportions and Laws of returns toScale.

 

Answer:When we talk about the main differences between Laws of returns to variable proportions and Laws of returns to Scale then there are many things to point out but to be specific and clear on the point, here I am sharing few most common factors that makes these two laws different from each other.

  • Average Fixed Cost
  • Marginal Cost
  • Average Cost

 

Answer:

 

  1. b) Can a monopolist incur losses in the short run? Explain how, with the help of example.

 

Answer:The market is considered complete with the presence of monopoly because it drives many changes and development to the business sectors. When we talk about the monopoly then we should know that monopoly exists only when any specific firm or person is the sole supplier of any specific particular commodity contrasts with another monopsony. It relates to the control of specific single entity of market for the purpose of purchasing services or goods. Therefore, Monopolies are classified by the deficiency of

Answer:Accounting, or accountancy, is the measurement, processing and communication of financial information about economic entities. It was founded by the Italian mathematician Luca Pacioli, in the end of the 15th century. Accounting, which has been called the “language of business”, measures the results of an organization’s economic activities and conveys this information to a variety of users including investors, creditors, management, and regulators. Practitioners of accounting are known as accountants. The terms accounting and financial reporting are often used as synonyms.

 

 

 

  1. 2. What is rectification of errors? List and explain the stages where theerrors are deducted for rectification.

 

Answer:Once an error is located, it should be properly corrected. The correction of accounting errors in a systematic manner is called the rectification of errors. In other words, the process of systematically correcting the accounting errors is known as rectification of errors. The presence of accounting errors affects accuracy of the profit and loss and the financial position of the business shown by the final accounts, therefore, no error should be

 

 

 

  1. 3. Explain the various steps in financial planning.

 

Answer:The financial planning process consists of the following six steps:

 

  • Establish and define the client-planner relationship: The financial planner should clearly explain and document the services that he or she will provide to you and define both his/her and your responsibilities during the financial planning engagement. The financial planner should explain fully how he or she will

 

 

 

 

  1. 4. What is inventory management and explain the following

 

Answer:Inventory management involves the Activities employed in maintaining the optimum number or amount of each inventory item.  The objective of inventory management is to provide uninterrupted production, sales, and/or customer-service levels at the minimum cost. Since for many companies inventory is the largest item in the current assets category, inventory problems can and do contribute to losses or even business failures.

 

  1. Economic Order Quantity: Economic order quantity (EOQ) is the order quantity that minimizes total inventory holding costs and ordering

 

 

 

 

  1. 5. Explain the different steps involved in preparation of Fund FlowStatements.

 

Answer:For preparing the Funds Flow Statement, the first step is to prepare the Statement of Changes in Working Capital. There may be several reasons for changes in the Working Capital Position of a Company, some of which have been discussed below:-

 

  • Purchase of Fixed Assets or Long Term Investments without raising Long Term Funds
  • Payments of Dividends in excess of the Profits

 

 

 

  1. 6. What is cost? Discuss the factors involved in estimating the cost.

 

Answer:In accounting, the term cost refers to the monetary value of expenditures for raw materials, equipment, supplies, services, labor, products, etc. It is an amount that is recorded as an expense in bookkeeping records.When a new company’s business plan is developed, organizers will often create cost estimates. These are used to assess whether the benefits and revenues of a proposed business will more than cover the costs. This is called a cost-benefit analysis.  Underestimating the costs of a business may result in a cost overrun once

Question. 1. Describe different types of Assemblers.

 

Answer:An assembly language (or assembler language) is a low-level programming language for a computer, or other programmable device, in which there is a very strong (generally one-to-one) correspondence between the language and the architecture’s machine code instructions. Each assembly language is specific to a particular computer architecture, in contrast to most high-level programming languages, which are generally portable across multiple architectures, but require interpreting or compiling.

 

There are two types of assemblers based on how

 

 

 

 

 

Question. 2. What is Language Processor? Explain about the two Languageprocessing activities.

 

Answer:By a language processor, we mean a program that processes programs written in a programming language (source language). All or part of a language processor is a language translator, which translates the program from the source language into machine code, assembly language, or some other language. The machine code can be for an actual computer or for a virtual (hypothetical) computer. If it is for a virtual

 

 

 

 

Question. 3. What is an assembly language? Explain its basic features. State theadvantage and disadvantages of coding in assembly language.

 

Answer:A programming language that is once removed from a computer’s machine language. Machine languages consist entirely of numbers and are almost impossible for humans to read and write. Assembly languages have the same structure and set of commands as machine languages, but they enable a programmer to use namesinstead of numbers.

Q3. Differentiate between packages and Interfaces.

 

Answer : Packages

Definition:  A package is a grouping of related types providing access protection and name space management. Note that types refers to classes, interfaces, enumerations, and annotation types. Enumerations and annotation types are special kinds of classes and interfaces, respectively, so types are often referred to in this lesson simply as classes and interfaces.

 

Creating a Package:

To create a package, you choose a name for the package and put a package statement with that name at the top of every source file that contains the types (classes, interfaces, enumerations, and annotation types) that you want to include in the

 

 

Q5 Compare JDBC and ODBC

Answer : Typically, software applications are written in a specific programming language (such as Java, C#, etc.), while databases accept queries in some other database specific language (such as SQL). Therefore, when a software application needs to access data in a database, an interface that can translate languages to each other (application and database) is required. Otherwise, application programmers need to learn and incorporate database specific languages within their applications. ODBC (Open Database Connectivity) and JDBC (Java

Answer : Swing is a GUI widget toolkit for Java. It is part of Oracle’s Java Foundation Classes (JFC) — an API for providing a graphical user interface (GUI) for Java programs.

 

Swing was developed to provide a more sophisticated set of GUI components than the earlier Abstract Window Toolkit (AWT). Swing provides a native look and feel that emulates the look and feel of several platforms, and also supports a pluggable look and feel that allows applications to have a look and feel unrelated to the underlying platform. It has more powerful and flexible components than AWT. In addition to familiar components

Q1 What is OSI model? Explain all its layers with diagram.

 

Answer : The OSI, or Open System Interconnection, model defines a networking framework to implement protocols in seven layers. Control is passed from one layer to the next, starting at the application layer in one station, and proceeding to the bottom layer, over the channel to the next station and back up the hierarchy.

 

There’s really nothing to the OSI model. In fact, it’s not even tangible. The OSI model doesn’t do any functions in the networking process, It is a conceptual framework so we can better understand complex interactions that are happening. The OSI

 

 

 

 

Q 2 What is Message switching and Packet switching?

Answer : Message Switching

This technique was somewhere in middle of circuit switching and packet switching. In message switching, the whole message is treated as a data unit and is switching / transferred in its entirety.

A switch working on message switching, first receives the whole message and buffers it until there are resources available to transfer it to the next hop. If the next hop is not having enough resource to accommodate large size message, the

 

 

Q3. List the design issues related to Data Link Layer.

 

Answer : The data link layer or layer 2 is the second layer of the seven-layer OSI model of computer networking. This layer is the protocol layer that transfers data between adjacent network nodes in a wide area network (WAN) or between nodes on the same local area network (LAN) segment.[1] The data link layer provides the functional and procedural means to transfer data between network entities and might provide the means to detect and possibly correct errors that may occur in the physical layer.

 

 

Q4.  Briefly explain Point-to-Point Protocol.

 

Answer : PPP (Point-to-Point Protocol) is a protocol for communication between two computers using a serial interface, typically a personal computer connected by phone line to a server. For example, your Internet server provider may provide you with a PPP connection so that the provider’s server can respond to your requests, pass them on to the Internet, and forward your requested Internet responses back to you. PPP uses the Internet protocol (IP) (and is designed to handle others). It is sometimes considered a member of the TCP/IP suite of protocols. Relative to the Open Systems Interconnection (OSI) reference model, PPP provides layer 2 (data-link layer) service. Essentially, it packages your computer’s TCP/IP packets and forwards them to the server where they can actually be put on the Internet.

 

 

 

Q5. Briefly explain five parts of Multipurpose Internet Mail Extensions.

Answer : Multipurpose Internet Mail Extensions (MIME)

Description

  • Multipurpose Internet Mail Extensions (MIME) is an Internet protocol used to send audio, video, programs, graphics and other binary files.
  • MIME specifies how to convert the non-ASCII data into ASCII allowing it to remain compatible with existing email protocols.
  • MIME defines five additional email header fields: MIME-Version, Content-Description, Content ID, Content-Transfer-Encoding, and Content-Type.
  • The Version field specifies the MIME version and informs the receiver that it is dealing with a MIME message.

 

 

Q6.  Distinguish between IPV4 and IPV6 addressing schemes

Answer : With the advent of Internet, there was a flow of information between the computers through Internet Protocol. IP Addresses were assigned to group of organizations/institutions to open up communication channels between computer networks. This kind of allocation was done through IPv4 Protocol. With the growing technology, there were growing demands of more such addresses for which the IPv4 was understated. Now, there has been news all around about IPv6 setup due to the scantiness of IPv4. But then what is it all about?

1 Differentiate between tightly coupled and loosely coupled systems

Answer : Loose Coupling means reducing dependencies of a class that use a different class directly. In tight coupling, classes and objects are dependent on one another. In general, tight coupling is usually bad because it reduces flexibility and re-usability of code and it makes changes much more difficult and impedes testability etc.

Tight Coupling

A Tightly Coupled Object is an object that needs to know quite a bit about other objects and are usually highly dependent on each other’s

 

 

2 Describe about Buffering. What are the four types of buffering strategies?

 

Answer : The transmission of message from one process to another can be done by copying the body of the message from the sender’s address space to the receiver’s address space. In some casses,the receiving process may not be ready to receive the message but if wants the oprating system to save that message for later  reception.Transmitted message can be stored prior to receiving process executing specific code to receive the message.

It is a loosely coupled distributed-memory system that has implemented a software layer on top of the message passing system to provide a shared memory abstraction for the programmers. The software layer can be implemented in the OS kernel or in runtime library routines with proper kernel support. It is an abstraction that integrates local memory of different machines in a network environment into a single logical entity shared by cooperating processes

 

 

4 Discuss any five features of good global scheduling algorithm

 

Answer : The decisions that the scheduler makes concerning the sequence and length of time that processes may run is called the scheduling algorithm (or scheduling policy). These decisions are not easy ones, as the scheduler has only a limited amount of information about the processes that are ready to run. A good scheduling algorithm should:

 

  • Be fair – give each process a fair share of the CPU, allow each process to run in a reasonable amount of time.
  • Be efficient – keep the CPU busy all the

 

 

5 What is replication? Discuss the three replication approaches in DFS

 

Answer : DFS Replication is an efficient, multiple-master replication engine that you can use to keep folders synchronized between servers across limited bandwidth network connections. It replaces the File Replication Service (FRS) as the replication engine for DFS Namespaces, as well as for replicating the Active Directory Domain Services (AD DS) SYSVOL folder in domains that use the Windows Server 2008 domain functional level.
