4 fundamental characteristics of Data Communication System

by
Data communication systems enable transfer of data using one of the three transmission modes. Data communication systems has 4 fundamental characteristics; which are delivery, accuracy, timeliness and jitter. Each of these 4 fundamental characteristics has it part in the effectiveness of a data communication system. However, data communication systems work through network systems and there are 3 necessary criteria for an effective and efficient network. Thus a data communication system also depend on the underlying network system’s effectiveness.

Data Communication Network

Data communications are the exchange of data between two devices using one or multiple forms of transmission medium using one of the three transmission modes. That is, data communication is movement of data from one device or end-point to another device or end point through electrical or optical medium. Systems that facilitates this movement of data between devices or end-points are called data communication network. There are 5 components of a data communication network. The devices which are in need to be a part of a data communication network made up of computer hardware and software.
