Inside the computer-Never Change

(An Atari XL 800 with its peripheral)

Those days most home computers setup look quite simple, consisting of a shallow plastic box with a keyboard on top. Yet inside are electronic circuits much more complex than those in a TV set. But who care, since you cannot see just how complex the circuits are because they are mostly concealed within tiny components called integrated circuits. These are often called silicon chips, as the microscopic circuits are formed on slices of silicon crystal. For most people using a computer is like using a TV, they won't learn inside out of it. Enough with learning how to operate it.

Remember those day when you can used your computer as a simple electronic calculator without having to load a program into its memory. This is an example of using the computer in what is called direct mode. Try that with today computer!.All this possible because when a home computer boots, its load the BASIC interpreter.

Then loading a program is necessary if you are to make full use of the computer power. That program can be a BASIC program or Machine Language Program. And sometimes we did learn theBASIC language in the sake to used our computer to the fullest. I'll really love this BASIC program, try to learn today language!. In fact I never get a gripped on today C language and its derivative.

We'll talk about BASIC language in the next post, see you ...
