Q.1 A box contains 20 fuses of which 5 are defective. If 2 fuses are chosen together at random, what is the probability that both the fuses are defective? 

 

Ans : Let A be the event the first fuse is defective and B the event that the second fuse is defective and A∩B represents the event the first fuse is defective and the second fuse is defective.

 

We use the concept of conditional probability o solve it and it states that :

 

The probability of an event B occurring when it is known that some event A has occurred is called a

conditional probability and is denoted by P(B/A)

The conditional probability of B, given A, denoted by P(B/A) is defined by:

P(B/A) = P(A)

P(A!B) if P(A) > 0

we may also write

 

 

 

Q.2 A coin is tossed until ahead appears. What is the expectation of the number of tosses   required?

 

Ans :  

 

Probability that it’s 1 is 1/2

Probability that it’s 2 is 1/2 x 1/2

–the first 1/2 is the probability that the first toss was a tail, the 2nd is that the second toss is a head.

Probability that it’s 3 is 1/2 x 1/2 x 1/2

Q. 6.Explain about the sampling distributions of a static and its standard error.

 

Ans :  Sampling distribution :

 

In statistics, a sampling distribution or finite-sample distribution is the probability distribution of a given statistic based on a random sample. Sampling distributions are important in statistics because they provide a major simplification on the route to statistical inference. More specifically, they allow analytical considerations to be based on the sampling distribution of a statistic, rather than on the joint probability distribution of all the individual sample values.

 

he sampling distribution of a statistic is the distribution of that statistic, considered as a random variable, when derived from a random sample of

Q.1 Write a brief note on:

a) Machine level language

b) Assembly level language

 

Ans : a) Machine level language :-

 

Machine code is the only language a microprocessor can process directly without a previous transformation. Currently, programmers almost never write programs directly in machine code, because it requires attention to numerous details which a high-level language would handle automatically, and also requires memorizing or looking up numerical codes for every instruction that is used. For this reason, second generation programming languages provide one abstraction level on top of the machine code.  The lowest-level programming language (except for computers that utilize programmable microcode) Machine languages are the

 

 

 

Q.2 Write any five comparisons of Intel and AMD processors.

 

Ans :  Intel Processor:-

 

Intel Corporation is an American multinational semiconductor chip maker corporation headquartered in Santa Clara, California. Intel is the world’s largest and highest valued semiconductor chip maker, based on revenue. It is the inventor of the x86 series of microprocessors, the processors found in most personal computers. Intel Corporation, founded on July 18, 1968, is a portmanteau of Integrated Electronics (the fact that “intel” is the term for intelligence information was also quite suitable). Intel also makes motherboard chipsets

 

 

 

 

Q.3 Differentiate between Interpreter and compiler.

 

Ans : A Compiler and Interpreter both carry out the same purpose – convert a high level language (like C, Java) instructions into the binary form which is understandable by computer hardware. They are the software used to execute the high level programs and codes to perform various tasks. Specific compilers/interpreters are designed for different high level languages.

 

Compiler:-

 

A compiler is a piece of code that translates the high level language into machine

language. When a user writes a code in a high level language such as Java and wants it to execute, a specific compiler which is designed for Java is used before it will

 

 

 

 

Q.4 What is addressing mode? Explain the four major addressing modes in 8086.

 

Ans : The 80×86 processors let you access memory in many different ways. The 80×86 memory addressing modes provide flexible access to memory, allowing you to easily access variables, arrays, records, pointers, and other complex data types. Mastery of the 80×86 addressing modes is the first step towards mastering 80×86 assembly language.

When Intel designed the original 8086 processor, they provided it with a flexible, though limited, set of memory addressing modes. Intel added several new addressing modes when it introduced the 80386 microprocessor. Note that the 80386 retained all the modes of the previous processors; the new modes are just an added bonus. If you need to

 

 

 

Q.5.What do you mean by Macro? Explain why it is required?

 

Ans : A macro (short for “macroinstruction”, from Greek μακρο- ‘long’) in computer science is a rule or pattern that specifies how a certain input sequence (often a sequence of characters) should be mapped to a replacement input sequence (also often a sequence of characters) according to a defined procedure. The mapping process that instantiates (transforms) a macro use into a specific sequence is known as macro expansion.

 

Types of MACRO:-

 

 

Q. 6 What do you mean by an ‘Interrupt’? Why it is needed? Explain the three major types of Interrupts.

 

Ans : Interrupts:

 

There are two main types of interrupt in the 8086 microprocessor, internal and external hardware interrupts. Hardware interrupts occur when a peripheral device asserts an interrupt input pin of the microprocessor.  Whereas internal interrupts are initiated by the state of the CPU (e.g. divide by zero error) or by an instruction.

Q.1. What is Java Development Kit (JDK)? Give list of all tools available for JDK with their description.

 

Ans :  A Java Development Kit (JDK) is a program development environment for writing Java applets and applications. It consists of a runtime environment that “sits on top” of the operating layer as well as the tools and programming that developers need to compile, debug, and run applets and applications written in the Java language.

People new to Java may be confused about whether to use the JRE or the JDK. To run Java applications and applets, simply download the JRE. However, to develop Java applications and applets as well as run them, the

 

 

Q.2 What Are Operators? Explain three kinds of Operators.

 

Ans : Java provides a rich set of operators to manipulate variables. We can divide all the Java operators into the following groups:

  • Arithmetic Operators
  • Relational Operators
  • Bitwise Operators
  • Logical Operators
  • Assignment Operators
  • Misc Operators

 

 

 

 

Q.3 What is an Exception? What are the common exceptions in JAVA? Explain the keywords used for exception-handlings with the help of an example.

 

Ans :  An exception is a problem that arises during the execution of a program. An exception can occur for many different reasons, including the following:

  • A user has entered invalid data.
  • A file that needs to be opened cannot be found.
  • A network connection has been lost in the middle of communications or the JVM has run out of memory.

Some of these exceptions are caused by user error, others by programmer error, and others by physical resources that have failed in some manner.

 

 

 

 

 

 

 

Q.4 Explain any 10 Packages in Swing Libraries.

 

Ans :  Swing is the primary Java GUI widget toolkit. 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

 

 

 

Q.5 Explain the process of Servlet Life Cycle with diagram.

 

Ans : A servlet is managed through a well defined life cycle that defines how it is loaded and instantiated, is initialized, handles requests from clients, and is taken out of service. This life cycle is expressed in the API by the init, service, and destroy methods of the javax.servlet.Servlet interface that all servlets must implement directly or indirectly through the GenericServlet or HttpServlet abstract classes.

 

 

 

 

Q. 6 What is Java Data Base Connectivity (JDBC).Explain JDBC Application Architecture with diagram?

 

Ans : The Java Database Connectivity (JDBC):-

 

The Java Database Connectivity (JDBC) API is the industry standard for database-independent connectivity between the Java programming language and a wide range of databases – SQL databases and other tabular data sources, such as spreadsheets or flat files. The JDBC API provides a call-level API for SQL-based database access.

The programming involved to establish a JDBC connection is fairly simple. Here are these simple four steps:

Q. 1. What are the different types of decisions? Explain with examples

 

Ans : Decision making is the heart of modern administration. According to M.T. Copeland, administration essentially is a decision making process. Whatever, an administrator does he does through decision making. An administrators life is filled with a constant series of decisions. Everyday hundreds of decisions are made by the administrator consciously or unconsciously. Decisions which are relatively minor are taken almost subconsciously following rules and patterns of behavior established over many previous encounters with the

 

 

Q. 2 Discuss Line organizations in detail.

 

Ans : Line organization:-

 

This is the oldest form of organisation. This is known by different names, i.e. military, vertical, scalar, departmental, organisation. All other types of organisation structure have mostly been either modifications of this organisation. The concept of line organisation holds that in any organization derived from a scalar process, there must be a single head who commands it. Although an executive can delegate authority, he has ultimate responsibility for results. According to McFarland, “Line structure consists of the direct vertical relationship which connect the positions and tasks of each level with those above and below it.” According to Allen,

Ans : Technique used by Mr. Narayan:-

 

Mr. Narayan can use the Management by Objective (MBO) Technique:

MBO relies on the defining of objectives for each employee and then to compare and to direct their performance against the objectives which have been set. It aims to increase the performance of the organization by matching organizational goals with the objectives of subordinates throughout the organization. Ideally, employees receive strong input to identify their objectives, time lines for completion, etc. MBO includes continuous tracking of the processes and providing feedback to reach

the objectives. According to George S. Odiorne, the system of

Together, the International Development Association and International Bank for Reconstruction

 

 

 

Q. 2 What are the types of assistance given by The International Finance Corporation?

 

 Ans : IFC:-

 

The International Finance Corporation (IFC) is the private sector lending arm of the World Bank Group, providing financial services to businesses investing in the developing world. As private enterprises often privilege “business confidentiality” over the public’s right to know, it is frequently difficult for the public to measure or influence the development impacts of the IFC’s activities.

Q. 2 Briefly discuss the reforms in the banking sector during 1992-2001

 

Ans : Various reforms are:-

 

1.Reduced CRR and SLR :

 

The Cash Reserve Ratio (CRR) and Statutory Liquidity Ratio (SLR) are gradually reduced during the economic reforms period in India. By Law in India the CRR remains between 3-15% of the Net Demand and Time Liabilities. It is reduced from the earlier high level of 15% plus incremental CRR of 10% to current 4% level. Similarly, the SLR Is also reduced from early 38.5% to current minimum of 25% level. This has left more loan able funds with commercial banks, solving the liquidity problem.

 

 

 

 

Q.3 Discuss the impact of convertibility both in current account and capital account.

Q. 5 Do you think poverty can be reduced through policies of inclusive growth? Justify

 

Ans : Yes poverty can be reduced through inclusive growth.

 

Justification:-

 

By definition, inclusive growth entails the equitable allocation of resources in order to generate benefits that can be incurred by all sectors of the society, thus alleviating poverty and inequality. Inclusive growth entails the equitable allocation of resources in order to generate benefits that can be incurred by all sectors of the society, thus alleviating poverty and inequality. However, is inclusive growth necessarily pro-poor? And does it ensure reducing the troubles of the most disadvantaged while benefiting everyone? There is yet no clear coherent measure to combine all the dimensions of inclusive growth that involves how the elements of
