Why are the Keys in a computer keyboard not arranged in Alphabetical order?

Friends, as all of you know the computer keyboard is very useful input device with a number of keys in it. We use it to enter data into computer. Just stop reading this post and observe your keyboard once. Read those alphabets. 

First Line :  Q W E R T Y U I O P

Second Line : A S D F G H J K L 

Third Line : Z X C V B N M

Have you ever wondered how nice it would be if these keys are arranged in Alphabetical order? I mean something like A B C D .... X Y Z ?

Then why don't they put them in that order instead of placing keys in this unusual Q W E R T Y order???

Once upon a time, there was a sooper hero named Khan Kapoor Kumar. He was very inteligent (He thinks so). Hez proud of his name. But unfortunately people dont call him with his name. They call him Politician instead.. As days passed by, our sooper hero came to know that the reason behind the villagers treating him like a Politician is because, he lacks of a small organ called BRAIN. So he made an Ironbox and gave some electricity to it. 

When he turned on the switch, it said YES, he marked it as 1
