A computer keyboard is defined as the set of typewriter-like keys that enables you to enter data into a computer or other devices. Computer keyboards are similar to electric-typewriters but contain additional typing keys.
The standard selection of keys typically found on computer keyboards can be classified as follows:
- Alphanumeric keys: The standard letters and numbers.
- Punctuation keys: The comma, period, semicolon, and similiar keys.
- Special keys: This includes the function keys, control keys, arrow keys, caps Lock key, and so on.
- QWERTY, AZERTY, Dvorak and Others
The standard layout of letters, numbers, and punctuation is known as a QWERTY keyboard because the first six typing keys on the top row of letters spell QWERTY. The QWERTY keyboard was designed in the 1800s for mechanical typewriters. This layout was actually designed to slow typists down to avoid jamming the keys on mechanical units.
