What is TCP vs UDP?

Two transport layer protocols: TCP provides reliable, ordered delivery while UDP provides fast, connectionless delivery without guarantees.

TCP (Transmission Control Protocol) establishes connections, guarantees delivery, maintains order, and handles congestion. It is used for web browsing, email, file transfer, and SSH where reliability matters.

UDP (User Datagram Protocol) is connectionless, lightweight, and fast but does not guarantee delivery or order. It is used for video streaming, gaming, DNS queries, and VoIP where speed matters more than perfect reliability.
