Let us start by taking an example of dissecting an Apple Macbook / ipad:
Finally on the circuit board, you will get to a bunch of Computer chips. That’s where they are, the 30 chips that you bought last year. The actual heart of the chip is actually present inside the chip’s outer protective cover as shown below.
The chips in the electronics gadgets you own are the ones you can see. There are chips that you don’t see, but still, you use them almost everyday. They are in the Cloud.
If you’re talking to Siri (or) if Google is completing your thoughts for you, this is accomplished by the chips present in the Cloud, doing all that work for you.
Example of a Cloud: The Google Data Center.
Facebook, Amazon, Microsoft etc., they all have these things.
Every row in this building is stacks of these boxes called servers.
Every server box has these cards.
And the cards have a lot of chips.
That’s the cloud. A bunch of chips in a building.
These data centers (or) Cloud are simply, huge computers connected together. The servers these days have incredible processing capability and efficiency. They can now run native applications like MS word, MS Excel inside them, and the user can access those applications through the web.
Example: Instead of buying and installing MS word / MS Excel on a computer, one can use Google Drive & Google Docs for free!
This use model where the servers do all the computation, instead of the user’s computer; is termed as Cloud Computing.
The chips are in Airplanes, Television sets, Music players, Washing Machines, Satellites, Rockets, Cars and you know.. Almost everywhere..
So, where do we start to learn more about these chips? Well to begin with, your smart phones have chips too..
But starting with something this complex will not be logical. Now that we have a brief idea about what a Computer chip is, it is time to define what a Computer is.
