Keypad

Definition - What does Keypad mean?

A keypad is a set of buttons or keys bearing digits, symbols and/or alphabetical letters placed in order on a pad, which can be used as an efficient input device. A keypad may be purely numeric, as that found on a calculator or a digital door lock, or alphanumeric as those used on cellular phones.

Techopedia explains Keypad

Aside from the row of number keys found on the upper portion of a computer keyboard, a separate numerical pad is also located on the right side for efficient data entry. For more compact computers such as laptops and notebooks, external plug-in keypads may be purchased separately.

Phone keypads are typically alphanumeric, allowing the user to enter names and text messages. They also provide an easier way of remembering phone numbers.
