At a guess, this refers to the 'Numeric Keypad' section of a full-sized PC (AT) keyboard. This is the block of keys to the right of the main 'QWERTY' (on an English keyboard) section which usually have cursor key functionality until the 'Numlock' is turned on. The numeric keypad is intended for speedy data entry by experienced users but also sees considerable use in games, for a variety of functions, typically 'camera control'.
because once you learn to type numbers on the numeric keypad, you can type them much faster, good for people who have to do a lot of calculations on their computers. When the standard QWERTY keyboard was introduced there were "text" type applications and data type. The key pad was added for the speed of entering numeric data in to fields and cells as in the case of spreadsheets. The number keys across the keyboard above the qwerty were to slow for many data punchers so the numeric pad was added
QWERTY keyboard layouts can vary slightly depending on the language for which it was made. Most QWERTY keyboards have three rows of letters, a row of numbers at the top, a spacebar key at the bottom, two shift keys, two control keys, two alt keys, and enter key, a backspace key, a tab key, and a caps lock key.

There are three patterns I know about, Azerty, Qwerty, and Dvorak, are close together (well, atleast Azerty and Qwerty) Azerty and Qwerty are practically the same. The only difference is that on a Azerty keyboard Azerty are the letters available to type on the top row on the left side, where as for Qwerty , Qwerty is the available to type in on the top right section. In Qwerty A and Z are right next to the caps lock and the (left) shift key. In Azerty Q is next to the bottom left shift key and W is next to the ,/< key. In Dvorak the five vowels are on the left side of the keyboard on the middle row and the five most commonly used consonants are on the left side. The ,/< , ./> and / or ? is on the upper left corner.
It is called a QWERTY keyboard because of the first 6 letters on your keyboard. Look at your keyboard and look at the first six letters at the top. It will be 'qwerty' hence the name.
