Hi everyone,
I found a question regarding socket, which I am finding it difficult to answer. The question is " How are connectionless sockets are different than connection-oriented sockets?"
1)Connectionless sockets can transmit to multiple receivers at the same time.
2)Connectionless sockets support only character streams.
3)Connectionless sockets are less efficient and slower
4)Connectionless sockets do not support two-way communication
5)Connectionless sockets do not gurantee delivery or order of receipt.
Please not that there is only one correct answer to this question out of five choices. Please help urgently.
Thanks in advance
Nilesh patel.

If I remember right, connectionless sockets are using UDP and connection-based sockets are using TCP/IP. TCP/IP guarantees that each data packet is received and UDP does not. TCP/IP is nice and sturdy that way, but it has more overhead than UDP.

Guaranteed delivery might cause problems in certain situation if it is delayed. The good example would be VoIP. TCP does not work well in which case.
