Answer :
The TCP (Transmission Control Protocol) standard created by the IETF (Internet Engineering Task Force) is always required. TCP ensures reliable delivery of data packets over the internet by providing error checking, flow control, and congestion control mechanisms.
The TCP protocol is a fundamental building block of the internet and is used for establishing connections and transmitting data reliably between network devices. It guarantees that data packets sent from one device are received correctly and in the same order by the receiving device. TCP performs error checking to detect and retransmit lost or corrupted packets, and it also manages the flow of data to prevent overwhelming the network or the receiving device. Without TCP, reliable communication and the seamless functioning of the internet would be greatly compromised. Therefore, TCP is always required for effective data transmission over the internet.
