Difference Between TCP and UDP Protocols in Computer Networks

In computer networks, TCP (Transmission Control Protocol) and UDP (User Datagram Protocol) are two common transport layer protocols with distinct characteristics.

TCP Protocol

• Connection-oriented protocol
• Provides reliable data delivery through error detection, retransmission, and acknowledgment mechanisms
• Guarantees packet sequencing and avoids data loss
• Suitable for applications that require high reliability, such as web browsing, email, and file transfer

UDP Protocol

• Connectionless protocol
• Does not guarantee reliable data delivery or sequencing
• Offers lower overhead and faster transmission speeds compared to TCP
• Ideal for time-sensitive applications like streaming media, online games, and VoIP

Overall, the choice between TCP and UDP depends on the specific requirements of the application in terms of reliability, speed, and connection overhead.
