A session is a set of processes which shares a controlling terminal. setsid is useful when you want to start a new session, because you have started to be connected to a new terminal — such as when starting a shell inside a terminal emulator — or you want a daemon (which you don’t want to be associated with a controlling terminal).
The best explanation I know of these aspect is in R.W. Stevens Advanced programming in the Unix environment.
