How Does a Clock Know When to Ring?

Imagine a clock as a sleepy friend who wakes up at the same time every day. Inside it, there's something called a timer that tells it when to ring. This timer is like a little counting machine, once it reaches the right number, it makes the bell go ding! Just like how your alarm knows when to wake you up.
