FUNDAMENTALS OF DATA COMMUNICATION PRINCE KUMAR BBA III ROLL NO. - 202
WHAT IS DATA COMMUNICATION ? Data Communication is defined as the exchange of data between two or more devices via some form of transmission media such as cable, wire, air or satellite also. For occurrence of data communication, the communicating devices must be a part of communication system made up of a combination of hardware devices, software and programs.
FUNDAMENTAL CHARACTERISTICS OF DATA COMMUNICATION 1. DELIVERY 2. ACCURACY 3. TIMELESSNESS 4. JITTER
1.DELIVERY In data communication, data and information are shared between two devices. When the data is sent from one end, it should be 100% delivered to the other end to successful data communication.This characteristics includes the security of the system, that is the protection of data. Therefore the delivery plays an essential role in the field of data communication. 2.ACCURACY The data communication system must deliver data to the receiver without being altered or damaged. The receiver should receive the exact same data which was sent by the sender. The protocol might require to alter the sent data to protect and optimize the process. However, the protocol should also reverse and restore the data back to its original form before representing it to the receiver. The accuracy must be maintained.
3.TIMELESSNESS The system must maintain timeliness. It must deliver data in a timely manner. Delayed delivery can make the data useless to the receiver. Data must be delivered as they are produced, in the order they are produced and without any significant delay. 4.JITTER Jitter refers to the variation of packet arrival time. Data is sent as packets, that is, a chunk of the whole data is sent in each turn. These packets get re-joined back in the target device to represent the complete data as it is.
