What is the key difference between TCP and UDP?
- ATCP is connection-oriented and reliable; UDP is connectionless and best-effort
- BTCP is connectionless and best-effort; UDP is connection-oriented and reliable
- CTCP is encrypted end-to-end; UDP is unencrypted and therefore always faster
- DTCP works only on local networks; UDP works only across the public internet
Why this is the answer
TCP sets up a connection and guarantees ordered, reliable delivery; UDP just fires packets with no setup or guarantees. The second option reverses them, and neither protocol is defined by encryption or by being limited to local versus internet use.
