wait process

can any one please give me clear idea of wait process in UNIX system.
I am using AIX 5.3 and see loots of wait process. I have very basic concept of wait process. If CPU has nothing to do then a wait process is generated per CPU. But i want know the detail how is it forked.
Is wait a jombe process?
does loots of wait results pagefaults?
please refer any documentations or replies...
thanks and regards
