What is the difference between TCP and UDP?
What will be an ideal response?
TCP and UDP are both Transport layer protocols, but TCP is considered reliable and UDP is considered unreliable. TCP is connection-oriented, which means that it forms a connection before it transmits data, thereby ensuring that the recipient is ready and waiting. The sender also waits for acknowledgements after sending data. This behavior makes it reliable. UDP is connectionless, so it sends data and doesn't wait to see whether anyone is listening; no acknowledgements are involved in the communication.
