TCP是面向连接、可靠传输、有序的协议,提供流量控制和拥塞控制;UDP是无连接、不可靠传输、无序的协议,传输效率更高。 1. 连接方式:TCP通过三次握手建立连接(SYN-SYN/ACK-ACK),UDP直接发送数据无需建立连接2. 可靠性:TCP使用确认应答、重传机制保证数据完整到达,UDP不保证数据送达3. 有序性:TCP通过序列号保证数...
TCP vs UDP: Differences between the protocols The main difference between TCP (transmission control protocol) and UDP (user datagram protocol) is that TCP is a connection-based protocol and UDP is connectionless. While TCP is more reliable, it transfers data more slowly. UDP is less reliable bu...
Another key difference betweenTCP and UDP protocolcomes from the fact that TCP is a connection-oriented protocol but UDP is a connectionless protocol. What this means is, before sending a message a connection is established between sender and receiver in TCP but no connection exists between the s...
