Sriram,

You are correct in your answer.

Another tidbit to keep in mind is that only switches support full duplex. If you use a hub (not sure how many still exist), you are forced to use half duplex.

Sometimes, when using a switch, your NIC may autodetect a 100Mb half duplex connection. This is a huge bottleneck, as the NIC can only send or receive, not both, at the same time. Therefore, always, always check your link. Don't trust that autonegotiate will do what is best. You'll always want a full duplex connection over a half duplex connection any day.
