Answer 2

If so:

A keyboard is the set of typewriter-like keys that enables you to enter data into a computer. Computer keyboards are similar to electric-typewriter keyboards but contain additional keys. The keys on computer keyboards are often classified as follows:
alphanumeric keys -- letters and numbers
punctuation keys -- comma, period, semicolon, and so on.
special keys -- function keys, control keys, arrow keys, Caps Lock key, and so on.

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.
