Basic Computer Hardware Information
This is a very short course about computers. It won't make you into a computer technician, but it will let you talk to one without thinking they are speaking a foreign language. The computers we are interested in are the general-purpose personal computers like we use at our desk, rather than the specialized computer under the hood of your car, or the big mainframe computers that the IRS uses to keep track of us all.
For our purposes, a computer can be defined as a machine for processing and storing information electronically. To be useful, it must have a way for us to get information into the machine, and some way to get it out afterwards so we can see it. Therefore, a computer has four basic functions:
1. Input
2. Processing
3. Storage
4. Output
