Why There are Different Types of Sockets?!

[f.ben.isaac]

Socket is Socket! The role of a socket to give you abilities to deal with different programs in different places on the internet....

Why its been said there are different types of sockets? What each of these types do? Don't they have one same role? Are these types differs in efficiency only?

I'm a newbie, so bear with me :-)

Just forget this dummy question. I got the answer ..... Sockets are not meant for internet communication only. There could be communication between two app. on the same machine, e.g. pipes uses a kind of socket to interact with another program in the same machine. This happens through socket descriptor..
