What is TCP?
TCP (Transmission Control Protocol) sets up a connection between two devices before sending any data, then makes sure every piece of data arrives in order and without errors. It splits data into segments, numbers them, and asks for retransmission if a segment gets lost or corrupted. Most applications that need reliability, like web browsing, email, or file transfer, run on top of TCP.
