TCP (Transmission Control Protocol) and UDP (User Datagram Protocol) are both protocols used for data transmission over networks, but they differ in how they handle communication.
TCP stands for Transmission Control Protocol. It is a connection-oriented protocol that ensures reliable and ordered delivery of data between devices on a network. TCP establishes a connection between sender and receiver, acknowledges receipt of data, and retransmits lost or corrupted packets to ensure data integrity.
HTTP (HyperText Transfer Protocol) primarily uses TCP as its underlying transport protocol. TCP is suitable for HTTP because it guarantees reliable delivery of web pages and other content. HTTP requires the assurance that data arrives intact and in the correct order, which TCP provides through its connection-oriented nature and mechanisms like flow control and error correction.
