TCP stands for Transmission Control Protocol and is a widely used protocol for transmitting data over the internet. It is a connection-oriented protocol that establishes a reliable connection between two endpoints before transmitting data. This is done using a three-way handshake where the sender sends a SYN message to the receiver, the receiver responds with a SYN-ACK message, and the sender sends an ACK message to confirm the connection has been established. Once the connection is established, data is transmitted in segments, and each segment is given a sequence number. The receiver sends an acknowledgment (ACK) message back to the sender for each segment received, indicating that it was received successfully. If a segment is lost or damaged during transmission, the receiver requests the sender to retransmit the segment. TCP also handles congestion control in the network to ensure the best possible performance. When all the data has been transmitted, the connection is closed using a four-way handshake. TCP provides reliable and ordered delivery of data between two endpoints and is an essential component of the internet.
