Different between Digital I/O and Timer/Counter

[coolzlk]

Dear...

As far as I'm aware, that both Digital I/O and Timer/Counter can record digital signals.

I'm really puzzled about the difference between Digital I/O and Timer/Counter, please kindly help me, thanks.

Dear...

I got one more puzzle about the Difference between Synchronous Timing and Asynchronous Timing?

Further more, I just want to know how to Realise both Synchronous Timing and Asynchronous Timing?

Please kindly help me.

With gratitude

Dear Coolzk,

Although generic digital I/O lines may be used to record digital signals for timing and synchronisation purposes, it is the counter ports on devices which allow precision monitoring of signals through the use of dedicated clock sources on board DAQ devices. Counters/Timers are much more accurate for high frequency signal measurement as they possess a greater resolution than ordinary digital I/O sources and can be operated at a much greater frequency.

Dear Alexander,

Thanks for your kindly reply and I think I understand the differences between DI/O and Timer/Counter now.
