What does TCP stand for?

TCP stands for Transmission Control Protocol. It is one of the core protocols of the Internet Protocol Suite, which is used for transmitting data over a network. TCP is responsible for ensuring reliable transmission of data, establishing a connection between devices before data is sent, and ensuring that packets are delivered in order. It does this through a series of mechanisms, such as acknowledgments and retransmissions of lost packets, which help to maintain the integrity and order of the data being transmitted. This reliability is particularly essential for applications where data loss or corruption would be detrimental, such as in web browsing, email, and file transfers.

The other terms mentioned in the incorrect options do not accurately represent the protocol's designation or its function in the network.
