How a computer works.

First what is a computer? A computer is an electronic machine that processes information—in other words, an information processor: it takes in raw information (or data) at one end, stores it until it’s ready to work on it, chews and crunches it for a bit, then spits out the results at the other end. All these processes have a name. Taking in information is called input, storing information is better known as memory (or storage), chewing information is also known as processing, and spitting out results is called output.

You have a Mother board, Monitor, Modem, System Unit, Mouse, Speakers, Keyboard, Hard drive, Hardware, Software, RAM, Floppy disk, CPU, Power plugin, and some/ most computers have a CD or and a DVD slot.

Your Inputs in your computer for a desk top PC are for your keyboard plugins, mouse plugins, microphone plugins, voice recognition plugins, USB stick plugins, and monitor plugin’s. For a PC laptop your Monitor, key board and mouse are in one, but practically have the same In and Out puts.

Your computer probably stores all your documents and files on a hard-drive: a huge magnetic memory. But smaller, computer-based devices like digital cameras and cellphones use other kinds of storage such as flash memory cards. Processing: Your computer’s processor (sometimes known as the central processing unit) is a microchip buried deep inside. It works amazingly hard and gets incredibly hot in the process. That’s why your computer has a little fan blowing away—to stop its brain from overheating!

Your computer probably has an LCD screen capable of displaying high-resolution (very detailed) graphics, and probably also stereo loudspeakers. You may have an inkjet printer on your desk top to make a more permanent form of output.
