What Is a Computer?

A computer is an electronic device that manipulates information, or data. It has the ability to store, retrieve, and process data. You probably already know that you can use a computer to type documents, send email, play games, and browse the Web. You can also use it to edit or create spreadsheets, presentations, and even videos.

Abbreviated as HW, Hardware is best described as a device that is physically connected to your computer, something tangible. Most hardware will contain a circuit board, ICs, and other electronics. A perfect example of hardware is a computer monitor, which is an output device that allows the user to interface visually with the computer. Without any hardware, your computer would not exist, and software would not be able to run.
