Explanation:
The above defined are the three requirements which are defined as the protocol used in communication. These three requirements are a very essential part of communication because-
- Message Encoding is the first requirement, which is used to encode the message so that the hacker can not hack the communication data from the network.
- The second requirement is Message size which fixed the size and the number of packets used to send for the communication.
- The third requirements are Message delivery, for which the protocol needs to define the mechanism to overcome the loss of the data.
