What are hardware clocks?

Hardware clocks are like invisible timers inside your phone or computer that help everything run on time.

Imagine you have a toy car that moves forward when you press a button. But what if it moved too fast, too slow, or not at all? That’s where a hardware clock helps, it keeps things going in a steady rhythm, just like a metronome.

Think of your phone as a busy little town with lots of people doing tasks. The hardware clock is like the town's main clock tower. It ticks every second, and all the other parts of the phone, like the screen or apps, listen to it so they know when to do their jobs.

Without hardware clocks, your phone might forget what time it is, or apps might get confused about when to show you a message. They're always working behind the scenes, making sure everything stays in sync, just like how your heartbeat keeps your body going!
