do you mean by data communication? Ans: It is the exchange of data between two devices via some form of transmission medium such as wire cable. The communicating system must be part of a communication system made up of a combination of hardware and software. The effectiveness of a data communication system depends on three fundamental characteristics: delivery‚ accuracy and timeliness. 2. What is simplex? Ans: It is the mode of communication between two devices in which flow of data is unidirectional

PARTS OF THE COMPUTER All computer systems need two types of parts that work together to make them run. These parts are: 1. Hardware - The hardware is the part of the computer you can touch and see. Eg: Keyboard‚ Mouse‚ Hard disk etc. 2. Software - The software is a part of the computer you cannot touch but is very important. The software is all the programming that makes the computer run; controlling everything that the computer does. Common
