A Protocol is one of the components of a data communications system. Without any protocol, communication cannot occur. For successful communication to occur, the sender and receiver must agree upon certain rules called the protocol.The sending device cannot just send the data and expect the receiving device to receive and further interpret it correctly.
When the sender sends a message it may consist of text, number, images, etc. which are converted into bits and grouped into blocks to be transmitted, and often certain additional information called control information is also added to help the receiver interpret the data.
A Protocol is defined as a set of rules that governs data communications.
A protocol defines what is to be communicated, how it is to be communicated, and when it is to be communicated.
There are three key elements of a protocol:
Syntax:
Semantics:
Timing:
