Sync means every device runs at the same (usually bus) speed

Async means every device runs at its own speed.

Although what u said is agreed  , but still  I am not clear about  how this works . Can it be explained with an example ?

Off the top of my head, all I can think of is CPU/RAM.

You can run then in Sync at 100MHz/100MHz (for example) or you can run them Async at 100MHz/133MHz

Another is the modem Uplink/Downlink connection. On a dialup it 33.6kbs/33.6kbs for Sync, and 33.6kbs/56kbs for Async.
