Qus:1 What is fiduciary relationship in a contract of guarantee? Explain the kinds of guarantees.

Answer: A contract of guarantee is not a contract “Uberrimae fidei” (requiring utmost good faith). Nevertheless, the suretyship relation is one of trust and confidence and the validity of the contract depends on the good faith of the creditor. A creditor must disclose all facts which, under the circumstances, the surety would expect not to exist. Hence, where the guarantee is given for good conduct of an employee, the employer’s failure to inform the surety of any breach on

Qus:2 i) Do you think contract with a minor is valid? Narrate with the help of the facts and judgement in the case: Mohori Bibee v. Dharmodas Ghose.

ii) Explain the rules and remedies for discharge of contract by breach

Answer: The law protects minors against their own inexperience and the possible improper designs of those who are experienced. The Contract Act states that only a person who is a major can enter into a contract. Section 3 of the Indian Majority Act, 1875, states that a minor is a person who has not

Qus:3 i) Narrate the facts and judgement in the case Howell vs. Coupland.

RESEARCH METHODOLOGY

1. Define business research and explain the process of research?

Definition of Research

Explanation of the steps in a research study

Answer: Different scholars have interpreted the term ‘research’ in many ways. For instance, Fred Kerlinger (1986) stated that ‘Scientific research is a systematic, controlled and critical investigation of propositions about various phenomena.’ Grinnell (1993) has simplified the debate and stated ‘The word research is composed of two syllables, ‘re’ and ‘search’.

Process of

2 What are descriptive research designs? Explain the different kinds of descriptive research designs.

[Meaning of Descriptive Research designs

Kinds of Descriptive research designs]

Answer: As the name implies, the objective of descriptive research studies is to provide a comprehensive and detailed explanation of the phenomena under study. The intended objective might be to give a detailed sketch or profile of the respondent population being studied. For example, to design an advertising and sales promotion campaign for high-end watches, a marketer would require a holistic profile of the population that buys such luxury products. Thus a descriptive study, (which generates data on who, what, when, where, why and how

3 Discuss four types of measurements scales with appropriate examples.

Nominal

Ordinal

Interval

Ratio

Answer: Types of measurements scales

Nominal scale: This is the lowest level of measurement. Here, numbers are assigned for the purpose of identification of the objects. Any object which is assigned a higher number is in no way superior to the one which is assigned a lower number. Each number is assigned to only one object and each object has only one number assigned to it. It may be noted that the objects are

4 Differentiate between the Stratified random sampling and Systematic sampling.

a. stratified random sampling

b. systematic sampling

Answer: Stratified random sampling

Under this sampling design, the entire population (universe) is divided into strata (groups), which are mutually exclusive and collectively exhaustive. By mutually exclusive, it is meant that if an element

5 Distinguish between coding closed-ended structured questions and coding open-ended structured questions

Coding Closed-ended

Coding Open-ended

Answer: Coding Closed-ended Structured Questions

The method of coding for structured questions is easier as the response categories are decided in advance. The coding method to be followed for different kinds of questions is discussed below.

Dichotomous questions: For dichotomous questions, which are on a nominal scale, the responses can be binary, for example:

Do you eat ready-to-

6. Explain the Structure of the Research Report. What are the guidelines for effective report writing?

1 Draw a diagram of OSI reference model and describe the role of each OSI layer.

Answer: OSI reference model

2 Explain the following:

a) Character stuffing

b) bit stuffing

Answer: a) Character stuffing

This method gets around the problem of synchronization after an error by having each frame start and end with special bytes. This method operates on bytes. The special bytes are reserved characters to indicate the start and end of a frame. A serious problem occurs when binary data like floating point numbers or object programs are transmitted. In such cases For instance, use the two-character

3 Explain the CSMA/CD protocol with suitable diagrams.

Answer: CSMA/CD Protocol

In computer networking, Carrier Sense Multiple Access with Collision Detection (CSMA/CD) is a network control protocol in which a carrier sensing scheme is used. A transmitting data station that detects another signal while transmitting a frame, stops transmitting that frame, transmits a jam signal, and then waits for a random

3 Mention and describe the different operations and responses with reference to Telnet protocol.

Answer: There are four modes of operation for most Telnet clients and servers.

1.       Half-duplex: This is the default mode, but rarely used today . The default NVT is a half duplex device that requires a GO AHEAD (GA) from the server before accepting user input. The user input is echoed locally from the NVT keyboard to yhe NVT printer so that only completed lines are sent from the client to the server. This provides the lowest common denominator for terminal support, but it does not

MIT208- ANALYSIS AND DESIGN OF ALGORITHMS

Assignment Set - 1

1 Differentiate algorithm, pseudocode, and program. Write the properties of an algorithm.

Answer: An algorithm is a finite set of unambiguous statement to solve a problem in finite amount of time. It can be natural language expressions designed for any common man. Analysis of algorithm means to study the specification of the algorithm and come to conclusions about how the implementation of that algorithm

2 Explain the various types of basic efficiency classes with suitable examples.

Answer: Even though the efficiency analysis framework puts together all the functions whose orders of growth differ by a constant multiple, there are still infinitely many such classes. (For example, the exponential functions an have different orders of growth for different values of base a.) Therefore, it may come as a surprise that the time efficiencies of a large number of algorithms fall into only

3 Describe the procedure to perform Mergesort using suitable example.

Answer: Merge sort is a sorting technique based on divide and conquers technique. With worst-case time complexity being Ο(n log n), it is one of the most respected algorithms. While comparing two sublists for merging, the first element of both lists is taken into consideration. While sorting in ascending order, the element

1 What is AVL tree? Briefly explain the four rotations in an AVL tree.

Answer: AVL tree is a self balanced binary search tree. That means, an AVL tree is also a binary search tree but it is a balanced tree. A binary tree is said to be balanced, if the difference between the hieghts of left and right subtrees of every node in the tree is either -1, 0 or +1. In other words, a binary tree is said to be balanced if

2 Define Principle of Optimality. Explain Knapsack problem with suitable example.

Answer: The principle of optimality states that an optimal sequence of decisions has the property that whatever the initial state and decision are, the remaining decisions must constitute an optimal decision sequence with regard to the state resulting from the first decision.

Because of the use of the principle of optimality, decision sequences containing subsequences that are suboptimal are not

3 Discuss an approximation Algorithms for NP – Hard problems.

Answer: Combinatorial optimization problems lie within a finite but huge feasible region. In this section, we focus on finding approximation algorithms for optimization problems that are NP-Hard.

Underlying principles

An NP-Hard problem is one for which the algorithm can be translated to one that can solve any NP-problem (non-deterministic polynomial time). Many optimization problems do not have an algorithm that can find a solution for all instances. Sometimes, when trying to find an optimal solution to some

1 Describe various types of attribute with reference to E-R model with suitable example.

Answer: The entity-relationship (E-R) data model based on a perception of real world that consists of a set of basic objects called entities, and of relationships among these objects. It was developed to facilitate database design by allowing the specification of an enterprise schema, which represents the overall logical structure of a database. The E-R data model is one of several semantic data models;

2 Define database manager. List and explain the important responsibilities of database manager.

Answer: A database manager is a program module which provides the interface between the low level data stored in the database and the application programs and queries submitted to the system. It is responsible for interfacing with file system. One of the functions of database manager is to convert user's queries coming directly via the query processor or indirectly via an application program from the user's logical view to the physical file system. In addition, the tasks of enforcing constraints to maintain the

3 What is catalog? What information is stored in the system catalogs?

Answer: A fundamental property of a database system is that it maintains a description of all the data that it contains. A relational DBMS maintains information about every relation and index that it contains. The DBMS also maintains information about views, for which no tuples are stored explicitly; rather, a definition of the
