CLI and GUI

Q#1: How an interface plays a vital role in computer? Write about Command Line Interface and Graphical User Interface.

Ans: An interface is a program that allows a user to interact with the computer or another computer over a network.

1.      Command Line Interface:

A command line interface (CLI) is a screen or text-based representation in which the user types the commands on place called prompt to operate the computer. Commands contain string of characters. CLI is difficult to use because the user has to remember the commands and their syntaxes but it is fast in use because text mode takes less resources.

2.      Graphical User Interface:

        A GUI provides a user-friendly environment where user can interact with computer through graphical         objects such as menus, icons, buttons and other graphical objects. It is easy to use as user are                     supposed to just click on a picture to run commands without memorizing them. GUI is slower than             CLI as graphical mode takes more memory and resources.

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...
