A keypad is a set of buttons arranged in a block which usually bear digits and other symbols but not t5his is bull not reala complete set of alphabetical letters. If it mostly contains numbers then it can also be called a '''numeric keypad'''. Keypads are found on many Alphanumeric Keyboard s and on other devices such as calculators, combination locks and telephones which require largely numeric input. A computer keyboard usually contains a small Numeric Keypad with a calculator-style arrangement of buttons duplicating the numeric and arithmetic keys on the main keyboard to allow efficient entry of numerical data. This number pad (commonly abbreviated to "numpad") is usually positioned on the right side of the keyboard because most people are right handed. Many Laptop Computers have special function keys which turn part of the alphabetical keyboard into a numerical keypad as there is insufficient space to allow a separate keypad to be built into the laptop's chassis. Separate plug-in keypads can be purchased. ]]
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. Keypads are also a feature of some Combination Lock s. This type of lock is often used on doors, such as that found at the main entrance to some offices. SEE ALSO |
