Define protocol

Question

Define the term protocol?  Why are standards required?

Answer 1

In the networks, communication takes place between the entities within the different systems. Two entities may not send the bit streams to one- another and expect to be understood. For the communication, the entities should agree on the protocol. A protocol refers to the set of rules which govern the data communication.

Co-ordination across nodes within the network is essential for the efficient communication. In cases there exist no standards, difficulties arise. A standard offers the model or basis for the development with which everyone has agreed.
