Data communication:-
It is the exchange of data between two devices via same form of transmission medium such as a wire cable for data communication to occur, the communicating devices must be part of a communication system made up of a hardware (physical equipment) and software (programs).
Characteristics of Data communication:-
• Delivery:- The system must deliver Data to the correct destination. Data must be received by the intended devices or user and only by that devices or user.
• Accuracy:- the system must deliver the data accurately. Data that have been altered is transmission and left uncorrected are unusable.
• Timelines:- The system must deliver the data in timely manner. Data delivered rate are useless. In the case of video and audio .
• jitter:- It refers to the variation in the packet arrival time. It is the uneven delay in the delivery of audio and video packets.
