Data Communication and Computer Networks Q#1: List the properties of a good communication system. Explain any one.    Ans:    1. Delivery   2. Accuracy   3. Timelines   4. Jitter  Accuracy: The system must deliver the data accurately. Data that has been altered during transmission and left uncorrected is not useful.  Q#2: Why OSI model is broken up in layers?  Ans: The OSI model is conceptual. It is broken up into layers so a person can visualize network communications and steps a computer takes when it encapsulates data from the application to the medium.  Q#3: Explain the purpose of Standard Organization.  Ans: Standard Organization develops, coordinates, revises, amends and reissues technical standards. These standards are intended to address the requirements of a group of concerned devices. There are several organizations working on standardization of computing equipment. IEEE, IETF, ITU and ANSI are ...

Problem Solving Steps

Q1: Describe the steps involved in problem solving.  Ans:  1) Define the problem:  In problem solving process, the first step is defining or identifying the problem. It is the most difficult and the most important of all the steps. During this stage of problem solving, it is important to describe the problem.  2) Generate alternative solutions: For any problem, there are more solutions to it than the one that is thought of first. Postpone the selection of one solution until several problem solving alternative have been proposed.  3) Evaluate and select an alternative:  Many alternative solution to the problem should be generated before final evaluation. A common mistake in problem solving is that alternative are evaluated as they are proposed, sop the first acceptable solution is chosen even if it is not the best solution.  4) Implement and follow up on the solution:  The plan for best solution also include planning on what happens next if somethi...
