About

It is a core component of the Internet Protocol Suite and provides a set of rules and procedures for data exchange between applications running on different hosts. TCP operates by breaking data into small segments known as packets, which are then transmitted over the network and reassembled at the receiving end. It handles issues such as flow control, congestion control, and error detection to ensure the reliable delivery of data. One of the main features of TCP is its ability to establish a connection between two devices known as a TCP session. This connection is established through a three-way handshake process, where the sender and receiver exchange certain control messages to synchronize their communication. TCP also provides mechanisms for handling congestion in the network. It uses a technique called congestion control, which ensures that the network does not get overwhelmed with too much traffic. By monitoring network conditions and adjusting the rate at which data is sent, TCP helps maintain a stable and efficient network. Furthermore, TCP includes features such as reliable data delivery and error detection. It adds sequence numbers to each packet, enabling the receiver to reorder them and detect missing or duplicate packets. If errors are detected, TCP will retransmit the affected packets to ensure accurate data delivery. Overall, TCP plays a crucial role in providing reliable and efficient communication over the internet. It has become the de facto standard for many internet-based applications, including web browsing, email, file transfer, and streaming media. Its robustness and versatility have made it an integral part of modern networking.
