UDP versus TCP protocols
The differences between the UDP and TCP/IP protocols can be listed as follows:
- UDP simply sends data, whether the data receiver is up and running or not. That’s why UDP is better suited to sending data compared to many other clients using multicast distribution. TCP, on the other hand, requires establishing the connection between the client and the server first. The TCP client sends a special control message; the server receives it and responds with a confirmation. The client then sends a message to the server that acknowledges the server confirmation. Only after this is data transmission between the client and server possible.
- TCP guarantees message delivery or raises an error, while UDP does not, and a datagram packet may be lost.
- TCP guarantees the preservation of the order of messages on delivery, while UDP does not.
- As a result of these provided guarantees, TCP is slower than UDP.
- Additionally, protocols require headers...
