The standard microcomputer keyboard consists of 104 keys arranged in the standard typewriter or QWERTY layout. A separate numeric keypad is at the right side of the keyboard and can be toggled on or off by pressing the “num lock” key. This numeric keypad may not be found in small size laptops and keywords.
QWERTY comes from the first six letters in the top row. It was invented by C L Sholes in 1872.
Keyboard v/s Game Console
Here we can note that the primary device for the PC is a keyboard and mouse, while all Game console systems come with game pads used to control movement within the game. Technically, a computer game can be thought of as one composed of a computer-controlled virtual universe. A video game is a computer game where a video display is the primary feedback, which is displayed on a television screen. It is the console system that takes advantage of the plug-and-play feature — there is no need to install the software or get different graphic cards, faster processors or CPU chips.
