What is a Keyboard?

The keyboard is the piece of computer hardware used to input text, characters and other commands into a computer or similar device.

Popular Keyboard Manufacturers

Microsoft and Logitech are the probably the most popular keyboard manufacturers but other hardware makers also produce them.

Keyboard Description

Modern computer keyboards were modeled after, and are still very similar to, classic typewriter keyboards. Many different keyboard layouts are available around the world but most keyboards are of the QWERTY type.

Many keyboards are wireless, communicating with the computer via Bluetooth or an RF receiver.

Wired keyboards connect to the motherboard via a USB cable, using the USB Type A connector. Older keyboards connect via a PS/2 connection.

Tablets and other computers with touch interfaces often don't include physical keyboards. However, most do have USB receptacles which allow external keyboards to be attached.

Laptops and netbooks have integrated keyboards but, like tablets, can have external keyboards attached via USB.

Even though the keyboard sits outside the main computer housing, it is an essential part of the complete non-tablet computer system.
