Program Plan Intro

TCP:

TCP stands for Transmission Control protocol. It is the most prominent used protocol on the internet. Establishing a path between the source and the destination represents the connection steering noted as the reliable service for sending message provided by TCP.

For example: If man A sends a message to man B, then man B acknowledges that messages and sent the acknowledgement to man A, then another acknowledgement comes from man A to man B.

UDP:

UDP stands for User Datagram protocol. It is also one of the most prominent used protocols on the internet. It generally provides unreliable service of sending messages.

For example: If man A sends a message to man B, but here the man A is not confirmed that does the man B has received his message or not. In this kind of protocol, message can take any path to reach its destination, there is no specific route for the transfer of message also there could be a possibility of losing message on the way of transfer.
