Data communication is the transmission and reception of information between two sites using electrical impulses. To transmit data, the communicating devices need to be a part of a communication system that consists of both hardware and software. To describe the phenomenon of data transfer, respond to the following questions. The Contribution of Data Communication Components to Effective Data Communication Systems ii. Consider the components of successful communication.
