What is TCP ? || Networking Tutorial

What is TCP? TCP stands for Transmission Control Protocol. Transmission Control Protocol (TCP) is one of the main protocols of the Internet Protocol or (IP) suite. The entire suite is commonly referred to as TCP/IP or TCP over IP. Roughly 80% of internet traffic uses TCP as its main method of communication. TCP is connection-based, meaning that the sender and receiver must establish a connection before any data is transmitted. Establishing a connection is done through what is called a three-way handshake First the sending machine sends a SYN packet Then the receiving machine responds with a SYN/ ACK packet Then the sending machine responds with an ACK packet This establishes the connection and the two machines will then communicate the desired data. TCP employs several network congestion and error avoidance measures. This includes the dropping and retransmission of any corrupted packets and it will also adapt its transmission speed to ensure reliable data transfer.
