The IAC is a small motor on the throttle body that screws a giant needle valve ("pintle") up and down. It regulates how much air is allowed to bypass the closed throttle plate, thereby controlling the idle speed. It moves up for example when you turn the a/c on, to kick it from the usual 900 to 1100 rpms. It's movement is controlled by the PCM (powertrain control module), to maintain the desired idle speed. There is not much to the throttle body... the throttle plate itself, the IAC motor (idle air control), attachments for vacuum lines, and a TP (throttle position) sensor to tell the computer what percentage the throttle is open.
