A "computer keyboard" is a primary input device to a computer consisting keys for alphabets, numbers, symbols, special characters and functions.

It can be connected to the computer via a USB cable or Bluetooth in case it is a wireless keyboard. The character keys are used to type text data into the computer, control keys help perform additional control over document (e.g. print screen, scroll lock), function keys are used as shortcut key to perform various functions like saving file. Additionally, it contains arrow keys for navigating left, right, up and bottom over the document. Laptop keyboard is different than the computer keyboard in terms of arrangement of the keys.
