Diploma in Information communication technology

DATA COMMUNICATION AND NETWORKING UNIT; Data communications are the exchange of data between two devices via some form of transmission medium such as a wire cable. For data communications to occur, the communicating devices must be part of a communication system made up of a combination of hardware (physical equipment) and software (programs). All these and networking are discussed fully in this unit.
