Without a matrix circuit, a 61-key keyboard for a digital piano or a computer keyboard might require 62 wires to connect (one for each key, and a ground)—an awkwardly thick bundle of wiring. With a matrix circuit, any of 61 keys can be determined with only 16 wires.
A keypad is a block or pad of buttons set with an arrangement of digits, symbols, or alphabetical letters. Pads mostly containing numbers and used with computers are numeric keypads . Keypads are found on devices which require mainly numeric input such as calculators , television remotes , push-button telephones , vending machines , ATMs ...
