Keyboard connection types

Keyboards can be connected to your computer with a cable (wired) or using wireless signals (wireless).

Wired

Wired keyboards are connected to the computer using a cable (generally USB) and do not require additional power source, such as

batteries.

Wireless

Wireless keyboards use Radio Frequency (RF) or Bluetooth (BT) to connect to your computer. Cable clutter is reduced and gives you the

flexibility to use the keyboard from a more comfortable position within a few meters from the computer. Such keyboards require batteries

to operate.

A keyboard that uses RF technology usually ships with a receiver that you must connect to your computer. Bluetooth keyboards can pair

with your computer’s built-in Bluetooth card or an external Bluetooth adapter.
