What are the main differences between TCP (Transmission Control Protocol) and UDP (User Datagram Protocol) in computer networking?
TCP provides reliable, connection-oriented communication with error detection, retransmission, and congestion control, while UDP offers faster, connectionless communication without guaranteed delivery or reliability mechanisms.
TCP prioritizes reliability and ordered delivery, while UDP prioritizes speed and low latency. The choice between TCP and UDP depends on the specific requirements of the application and the trade-offs between reliability, speed, and overhead.
TCP (Transmission Control Protocol) is one of the main protocols of the Internet protocol suite. It lies between the Application and Network Layers which are used in providing reliable delivery services. It is a connection-oriented protocol for communications that helps in the exchange of messages between different devices over a network. The Internet Protocol (IP), which establishes the technique for sending data packets between computers, works with TCP.
User Datagram Protocol (UDP) is a Transport Layer protocol. UDP is a part of the Internet Protocol suite, referred to as the UDP/IP suite. Unlike TCP, it is an unreliable and connectionless protocol. So, there is no need to establish a connection before data transfer. The UDP helps to establish low-latency and loss-tolerating connections establish over the network. The UDP enables process-to-process communication.
