Imagine that the inside of you computer is an office cubicle. The office cubicle has a few items of interest. In the office sits a desk, a file cabinet, an office worker seated in a chair, and a special fax machine. First of all, the file cabinet represents your hard drive. This is where all information is stored. The desk represents the memory or RAM of your computer. This is where all the files currently in use are at. Next, the office worker represents the CPU of your computer. He is the one that does all the real work around here. And lastly, the special fax machine represnts a graphics card. When the boss needs to see something, the worker puts a paper on the fax machine and it comes out on the other end of the line as a picture.
