Types of computers

  Computers can be classified as one of three types of computers: a general-purpose computer, special-purpose computer, or specialized computer.

general-purpose computer is what most people think of when thinking about a computer and is what this page covers.

A special-purpose computer is embedded in almost all electronic devices and is the most widely-used computer. This computer is designed for a specific task and is found in ATMs, cars, microwaves, TVs, the VCR (Video Cassette Recorder), and other home electronics. See our special-purpose computer page for further information and examples.

A specialized computer is like a general-purpose computer but is designed only to perform one or a few different tasks. See our specialized computer for further information and examples of these computers.

When discussing a computer or a "PC," you're usually referring to a desktop computer found in a home or office. However, the lines of what makes these computers are blurring. Below are different examples of what's considered a computer today.

Desktop computer, laptop, hybrid computer, tablet, and smartphone

The picture above shows several types of computers and computing devices and is an example of their differences. Below is a complete list of general-purpose computers of past and present.
