A detailed Summary of computers 2

People use computers everyday. Some people know how to use one some people don't. But not too many people can understand how the computer works and its processing. I have been taught how it works and I understand it very well. The best way to explain it would be to compare it to the United States Postal Service and how it works.

Computers are always being upgraded and there have been major advances in mail since it has started.

On a computer the user does some sort of input whether it be a keyboard or mouse, this input is taken to the computers RAM, where it is temporarily stored. Then different commands are brought from the hard drive and in the central processing unit (CPU), the commands are executed and then any output is displayed on the screen.

The post office workers who sort, cancel, check postage, and other mail related things, would be the different commands brought in from the Hard Drive. Where all this action is being taken place would represent the Central Processing Unit. Then the letters are then sent out to either another city or kept in the same city and sent to the address that the sender sent it to. Unless it gets sent to the wrong address, which happens, and in a computer errors also can happen.

Computers and USPS have evolved so much since they first started. The USPS was formerly known as the Pony Express where letters were delivered on horseback and it could take weeks or months for letters to get across the United States. Now we have airplanes that get letters across the United States in just a fraction of the time it u
