Data communication and networking notes pdf

Data communication and networking notes outline and the notes in pdf highlighted here. Data communication and networking unit is examinable by Kenya national examination council KNEC and is mainly taught in various courses highlighted below;

  • 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.
