Why do HTTP, SMTP, and POP3 use TCP rather than UDP when it comes to communication?
Introduction
Transmission Control Protocol is referred to as TCP. The packet transmission between source to destination is made easier by this transport layer protocol. Because it is a direct link protocol, communication between computer devices within a network begins with the link being established. Combined, these are usually known as TCP/IP since they are utilized with an IP protocol.
The TCP's primary role is to retrieve data to the application layer. The data is then divided into numerous packets, each of which is given a number, before being transmitted to the destination. The packets are reassembled by the TCP and routed to the application layer from the opposite side. Since TCP is a direct link protocol, the connection will continue to exist as long as the sender and receiver are still in contact.
