What does TCP stand for in network communication?

Transmission Control Protocol
Transfer Control Protocol
Transmission Congestion Protocol
Transfer Congestion Protocol

The correct answer is: Transmission Control Protocol

TCP stands for Transmission Control Protocol in network communication. It is one of the primary protocols in the Internet Protocol Suite, widely used for transmitting data over networks. TCP is responsible for ensuring reliable, ordered, and error-checked delivery of data packets between applications running on hosts communicating over an IP network. The significance of TCP lies in its ability to establish a robust connection between a client and a server, managing the transfer of data in a way that guarantees all packets are received and in the correct sequence. This is crucial for applications that require high integrity of data, such as web browsing and email. In contrast, the other options do not accurately define TCP or its purpose. For example, "Transfer Control Protocol," "Transmission Congestion Protocol," and "Transfer Congestion Protocol" do not exist as standardized networking terms and fail to capture the essence and functionality of TCP as established in network communication protocols.
