Answer from AI
UDP (User Datagram Protocol) and TCP (Transmission Control Protocol) are two main transport protocols in the TCP/IP stack, differing in data transmission method:
-
TCP provides reliable, connection-oriented data transfer. It establishes a connection between sender and receiver, guarantees delivery of packets in order, checks for errors, and retransmits lost data if necessary. Suitable for applications where data integrity and order are important (e.g., web, email).
-
UDP is a connectionless protocol that simply sends packets (datagrams) without acknowledgment of delivery. It is faster and simpler but does not guarantee delivery, order, or integrity. Used where speed is critical and some data loss is acceptable, such as streaming video, voice calls, gaming.
Summary:
- TCP: reliability, error control, order, slower
- UDP: speed, simplicity, no delivery guarantees
These are key differences in network communication.
