Transmission Control Protocol (TCP)

Transmission Control Protocol (TCP) is a fundamental communication method used in computer networking. It ensures that data sent over the internet arrives accurately and in the right order. Think of TCP as a postal system: it breaks messages into smaller pieces, numbers them for order, and checks that each piece arrives successfully. If anything is missing or out of order, TCP requests the sender to resend the necessary pieces. This reliability makes TCP crucial for applications like web browsing, email, and file transfers, where accurate data delivery is essential.
