The benefit of using TCP (Transmission Control Protocol) lies in its reliability. TCP ensures that data transmitted between devices arrives intact and in the correct order by employing mechanisms such as error checking, retransmission of lost packets, and flow control to manage data transmission rates.
The purpose of using TCP is to establish a reliable connection-oriented communication between devices over a network. TCP guarantees the delivery of data packets in the correct sequence and ensures that no data is lost or corrupted during transmission, making it suitable for applications where data integrity and accuracy are critical.
TCP and UDP (User Datagram Protocol) offer distinct benefits depending on the requirements of the application. TCP provides reliable, ordered, and error-checked delivery of data packets, making it ideal for applications such as web browsing, email communication, file transfer, and database transactions where data accuracy and completeness are paramount. UDP, on the other hand, offers lower latency and faster transmission speeds since it operates without establishing a connection or ensuring data reliability. UDP is preferred for applications like real-time video and audio streaming, online gaming, and DNS queries where timely delivery of data is prioritized over data integrity.
