[HardWare] KeyBoard Computer

[Mihawk.]

The keyboard or the button is a basic panel that consists of buttons for entering data into a computer via buttons. These buttons are written letters, numbers, or symbols. In the early 1960s, the first computer keyboards appeared at the same time as the first operating systems used on the command line. In order not to confuse users, they were inspired by TTY keyboards and typewriters, which are divided into four categories: Station balls (touch typing spins a bearing ball that prints different characters), with or without spooling of a line of text before sending it (eg IBM 2741); Telephone type devices, with or without a punch tape reader (eg ASR33, KSR33) screens associated with a memory buffer. Keyboards coupled with a "full screen" (full screen) display with programmable regions (eg IBM 327x series). In the late seventies, keyboards were allocated to the country by major manufacturers and domestic companies (it costs as well as burning ROMs and checking some keys). 

keyboard layout : Before the invention of the computer, the typewriter existed and many characters were taken from the typewriter layout to the computer keyboard. As a journalist and writer named Christopher Schulze is the inventor of the typewriter in 1874, after several attempts and many failures in designing the keyboard, this design succeeded and he sold it to a company. At first, the layout was arranged alphabetically. Then, according to the advice of one of Christopher's colleagues, he tried to put the most frequently used letters in the main row. He re-layed the keyboard according to the most commonly used and common letters. This layout is called QWERTY, which is the name of the first six letters on the keyboard. Another important layout is the Dvorak Simplified Keyboard.
