Data Communication? Characteristics of Data Communication


Data communications are the exchange of data between 2 devices via some form of transmission medium such as a wire cable.
The effectiveness of Data communication depends on 4 characteristics-
1. Delivery – The system must deliver data to the correct Destination. Data must be received by a specific user or device.
2. Accuracy – The system must deliver the data accurately. Data that have been altered in transmission and left uncorrected are unusable.
3. Timeliness – The system must deliver the data in a timely manner. Data delivered late are of no use.Especially in the case of Video or Audio streaming, timely delivery of data is very important. This is called as Real-Time transmission.
4. Jitter – This refers to the variation in the packet arrival time. It is the uneven delivery in the streaming audio or video packets.
