Computer Gens.

Have you ever seen a computer that only gives out numbers on its screen.
Well me? NO WAY.
Its a way back in 40's to see these kinds of stuffs.
First, let me introduce to you how this computers are categorized into different generations.
First of which is to see the technological development on these PC's.
Technological development is to see how faster, how much a normal human to understand what it flashes on its screen and how cheaper and how smaller they are.
1st generation machines are those with vacuum tubes, they flashes out 0's and 1's.
2nd gen machines are those with transistors which are just more efficient and smaller version of vacuum tubes.
3rd gen machines are those with IC's(Integrated Circuits), this one is still using transistors but a lot of transistors, there are lots of transistors in one IC.
4th gen machines are those with microprocessors. These microprocessors are still being used, being improved and a little bit being more expensive.
As they have newer versions, they have a little bit more efficiency, as far as I know its newest or most efficient was Intel's i7 Extreme Core.
The 5th and latest one was the Artificial Intelligence. This generation of computer is capable of thinking factual things like a human person can do, but the thing is it cannot decide by itself in terms of romantic stuffs.
Watson was the best known in this generation. He can be asked factual questions and he can answer it by himself.
