World of Computer Networking Your CCNA start - Transmission Control Protocol (TCP) versus User Datagram Protocol (UDP)

The video tutorial explains the differences between TCP and UDP protocols. TCP is a connection-oriented protocol requiring connection establishment and teardown, making it slower but reliable due to flow control and error recovery. UDP is connectionless, faster, and simpler, with no flow control or retransmissions. The tutorial also provides examples of application layer protocols that use TCP and UDP, such as HTTP, FTP, DNS, and Skype.
