The keypad of a Calculator contains the digits 0 through 9, together with the four Arithmetic operations, the Decimal Point and other more advanced functions. The term keypad can also refer to the part of a computer keyboard that contains a calculator-style arrangement of buttons - many of them duplicating existing keys on the main keyboard - allowing efficient entry of numerical data. On most Laptops , special function keys have to be depressed to turn part of the alphabetical keyboard into a numerical keypad as there is insufficient space to allow a keypad to be built into the laptop's chassis. Presumably because most people are right-handed, the keypad part of a keyboard appears on the right side of the keyboard. Separate plug-in keypads can be purchased.
A keypad can also refer to the series of numbered buttons, similar to a telephone keypad, used as part of a Combination Lock . This is often used to allow multiple entry to doors, such as that found at the main entrance to some offices. SEE ALSO |
