Keyboard is a standard input device. It is a data entry platform of a computer. A computer key board is a sophisticated electromechanical component designed to create specialized electronic codes (scan codes) when a key is pressed. These codes are transmitted along the cables to computer system unit or terminal, where the incoming code is analyzed and converted in to the appropriate computer usable code.
Keyboards have five distinct groups of keys:
Keyboard Layout defines the position of keys in a keyboard. QWERTY is the most popular keyboard layout. Dvorak, Colemak, JCUKEN are other keyboard layouts for Latin scripts. Similarly, we have Traditional, Romanized and Nepali keyboard layout for typing Unicode Nepali script. You can change keyboard layout from Regional and Language Settings in Control Panel.
Why are traditional keyboard layout places keys in the QWERTY order? Why they are not alphabetically ordered like ABCDEF….? You’ll really surprise to know that it was developed to make typing harder and inefficient (do some Googling on this topic). Devorak layout is far better in keys arrangement and improves the speed and accuracy of typing, but the more surprising thing is that it is not much common compared to traditional QWERTY.
By now, I hope, you don’t confused types of keyboards as QWERTY, Dvorak and so on. They are not type of keyboards but rather the types of keyboard layout. At the same time, I want to make it clear that the type, as our course defines, is not related to switch technology either. We look on the history of keyboard and classify keyboards into four types based on the technology used.
PC/XT, PC/AT, Enhanced and Windows are the four types of keyboard.
