TCP (Transmission Control Protocol) and UDP (User Datagram Protocol) are two of the most commonly used protocols in the Internet Protocol suite. They are both used to establish connections between two hosts, but they differ in the way they transfer data.
Firstly, TCP is a connection-oriented protocol that requires a connection to be established before data can be transferred. It is reliable, meaning that all data is checked for errors and resent if necessary. In addition, it is a stream-oriented protocol, meaning that data is sent in chunks, allowing for an efficient and continuous flow of data.
Moreover, UDP is a connectionless protocol that does not require a connection to be established before data can be transferred. It is an unreliable protocol, meaning that data errors can occur, but it is not checked for errors or resent. Further, it is a packet-oriented protocol, meaning that data is sent in packets, allowing for more control of the data transfer.
