"Computer is  an electronic machine that changes raw facts and figures to a meaningful form." 
So now that you know what a computer is, you'll understand why the hell does a computer talk the language of 1s and 0s. But for those who still do not know what a computer is, I'll briefly explain it to them.
So here it goes!!!

Every day, you check your Facebook, Twitter, MySpace, LinkedIn, Google+ account, via your computer. During that time, your computer sends and receives a lot of things that you, own your own, would think 'What the hell is this?'. But your computer changes all that to something you can easily understand.In the morning, you turn on your TV and watch news, cartoons, movies or whatever you like. Your TV receives Radio waves, that it changes to picture.Your phone rings; you pick it up and start to talk with your friend, family member or colleague.During your conversation, your mobile changes your spoken words to electrical signals, that travel all the way to the receiver, and then his/her phone changes the signals to sound again, and Vice Versa.

Hope you now know what a computer is. So lets get back to the topic.
As I earlier said, "Computer is an electronic machine", it has many many circuits built inside it. when you press the key 'A', your keyboard sends a combination of 1s and 0s through a bundle of 7 wires.
