Wake-on-ring

Wake-on-ring is a fancy feature on your computer that allows it to wake up from sleep mode when it hears a special ringing sound. Just like how your parents might wake up when you shout their names loudly, the computer can wake up too if it hears a ringing sound.

But, how does the computer recognize the ringing sound? Well, first, you need to connect your computer to a phone line or modem. When someone calls you, the phone line sends a ringing sound to the modem. Then, the computer wakes up and checks if the call is for you. If it is, then you can answer the call using your computer.

This feature is usually used by businesses that have a lot of incoming calls. They can leave their computers on sleep mode to save energy, but still be able to answer calls quickly without having to manually wake up each computer.

So, that's basically what wake-on-ring is all about. It helps you save energy and be more efficient when handling incoming calls on your computer.
