What are UDP and TCP

Question

Discuss the term UDP and TCP.

Answer 1

UDP (User Datagram Protocol) is defined as the communications protocol which provides a limited amount of service when the messages are exchanged between the computers in network, which uses the Internet Protocol (IP). UDP seems an alternative to Transmission Control Protocol (TCP) and, together with IP, it is sometimes referred to as UDP/IP. Just like the Transmission Control Protocol, UDP utilizes the Internet Protocol to obtain the data unit (termed as a datagram) from one computer to the other.

TCP (Transmission Control Protocol) is defined as a set of rules (protocol) utilized along with the Internet Protocol (IP) to transmit the data in form of message units between the computers over Internet. However, the IP takes care of handling actual delivery of data; TCP takes care of keeping the track of individual units of data (known as packets) that a message is decomposed into for efficient routing through Internet.
