Computers

I always thought a computer was just, well, a computer. I thought your computer, tv, and phones were just computers with different names. They're all programmed to do something special, but they aren't all computers. Some electronics have computers in them though.

Computers must have a control system built in, you aren't in control of it. As I mention that some electronics have computers in them, this is seen more and more as technology advances. This is possible with four different computer categories. Those categories are : Information Appliance, Microcomputers, Minicomputers, and Main frames.

Informational Appliances would be like a Smart Phone or PDA. The informational Appliance is designed to perform a specific user friendly function. Another example would be an iPod.
The Microcomputer is your typical personal computer. They include keyboards, input/output devices,batteries, power supply unit, and memory storage.
Minicomputers were used in manufacturing processes or handling email that was sent or received by a company.
Main Frames process bulk data (like the census).
(They are listed in order from the smallest to the largest.)

Today, as the Microcomputers become smaller and cheaper we are seeing them put into more electronics. This is our typical everyday computer that got turned into our phones and game systems.
