Describe network protocols : TCP Protocol

The video tutorial covers programming TCP clients and servers, explaining the TCP protocol's workings, including connection establishment, reliability, and flow control. It discusses creating a simple TCP ECHO server, modifying it for multithreading, and handling network connections with thread pools. The tutorial emphasizes understanding TCP's connection-oriented, full-duplex nature, sequence numbers, and sliding window mechanism for efficient data transfer. It also highlights TCP's performance considerations, such as congestion control and the impact of CPU speed on network communication.
