TCP
Transmission Control Protocol (TCP) is a Transport Layer protocol that delivers reliable end-to-end communications between host applications. TCP's characteristics and features include:
- error correction
- flow control
- connection-oriented
- congestion control
It is one of the main protocols in the TCP/IP suite and complements the Internet Protocol (IP). UDP is another prominent Transport Layer protocol that, unlike TCP, is considered connectionless and unreliable.
