1. Connection: TCP is a connection-oriented protocol, meaning it first establishes a connection before transmitting data. UDP, on the other hand, is a connectionless protocol, which means it does not establish a connection before sending data.

2. Reliability: TCP is more reliable as it ensures delivery of packets in the same order they were sent. It uses acknowledgments to confirm the receipt of data. UDP does not guarantee delivery because it does not use acknowledgments.

3. Speed: UDP is faster than TCP because it does not need to establish a connection and does not use acknowledgments. TCP is slower because it takes time to establish a connection and to ensure the reliable delivery of packets.

4. Usage: TCP is used when reliability is more important, such as in web browsing, email, and file transfers. UDP is used when speed is more important, such as in video streaming, online gaming, and voice over IP (VoIP).

5. Header Size: TCP has a larger header size (20 bytes) compared to UDP (8 bytes), which makes TCP more complex and UDP simpler.
