How Computers Work?

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.

• Input :

  An input is the information that we provide to the Computer. We provide the information using the Computer’s input devices: Keyboard, mouse, microphone, and many more. For example, when we type something using a keyboard, it is known as an Input provided to the Computer.

• Process:

  our 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.

the computer does temprory or primary storage

• Output

  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 too to make a more permanent form of output
