Why are clocks (or timers) discussed in the context of I/O systems?
Solution
1) Time operations are not standard across all systems.
2) A timer can be used to trigger operations and to measure elapsed time. It can be set to trigger
an interrupt at a specific future time, or to trigger interrupts periodically on a regular basis to take
place.
3) Provide current time, elapsed time, etc.
