Alternatively referred to as the 10-key, number pad, numeric keyboard, numpad, or ten key, the numeric keypad is a 17-key keypad usually found on the far right side of a standard PC keyboard. A numeric keypad may also be a separate device that can connect to a computer. To enable and disable the numeric keypad, press the num lock key.
Below is a visual example of the Saitek keyboard and where the keypad is located on almost every computer keyboard.
A numeric keypad may also be a separate device, not built into a keyboard. Numeric keypads usually connect to a computer with a USB cable, but older keypads may use a serial connector instead of USB. Some separate numeric keypads have a single-line LCD screen, like a calculator and the Kensington keypad to the right.

By being proficient, this means you know how to place your hand on the 10-key and can enter numbers quickly and without having to look down at the keypad.
