A computer’s hardware is all the parts of the computer that take up physical space. These parts include:
|The Tower or Case, which contains the electrical connections and the Central Processing Unit (CPU), which is the major computer chip inside that runs the computer.|
|The monitor is a screen that provides the visual indication of what the computer is doing inside.|
A mouse is a hand-held pointing device that allows you to control the movement of the cursor on the computer screen. The cursor acts as a virtual finger that presses buttons and selects items on the screen. A mouse has one or more buttons and often features a scroll wheel.

Keyboards come in various shapes and sizes and are also used to communicate with the computer. They resemble typewriter keys and work in much the same way.

|All of the computer components together are referred to cumulatively as a desktop system.|
|Laptops are small, compact computers that can easily be carried from place to place. Laptops combine the computer, monitor, and keyboard into a single unit, and they usually have a touchpad instead of a regular mouse. Moving a finger over the touchpad controls the cursor just like moving a mouse over a desk.|
|Smartphones are mobile phones that are built like computers. They have more functions than feature phones, including Internet connectivity, and serve as mini computers.|
|Tablets or tablet computers are mobile computers that are larger than smartphones but smaller than laptops, though they function similarly. Tablets are flat and typically operate with a touch screen instead of a keyboard and mouse.|
