What kind of keyboard is divided into uses?

From the point of view of use, the keyboard can be divided into three categories: desktop keyboard, laptop keyboard and industrial computer keyboard; among them, the desktop keyboard can be divided into two categories from the button structure, namely mechanical keyboard and capacitive keyboard also known as touch Point keyboard and contactless keyboard . The mechanical keyboard has the disadvantages that the switch is easy to damage, easy to pollute, and easy to age, and has been basically eliminated. Capacitive keyboards have a qualitative leap in reliability compared to the former, and have a long service life. Currently, most of them are capacitive keyboards.
The early keyboard was introduced by IBM in the United States, and the computer keyboard used at that time was a 83-key keyboard. Soon after, IBM introduced the 84-key keyboard design standard, which divided the keyboard into three areas, namely the function area, the typing key area and the sub-keyboard area responsible for cursor control and editing. The division standard of the main area of ??the keyboard has been used until now. With the wide application of Microsoft Windows Windows operating system, IBM first introduced the 101-key standard keyboard in 1986. In addition to adding the F11 and F12 function keys, a special set of cursors was added in the middle of the keyboard. Control and editing of the keys, the keyboard function has been further expanded, becoming the standard keyboard of the industry at that time. Later, in conjunction with Microsoft’s Win95 operating system, IBM introduced a 104-key keyboard and added three function keys also known as Windows shortcut keys or hotkey , which required several windows to be completed before. Some of the functions are directly activated by the shortcut key setting without having to click the mouse, which makes the operation of the computer easier. At present, the design of the 104-key keyboard also known as Win95 keyboard has become the most common and popular standard in the industry and the market, and the industry is commonly known as the standard keyboard. In fact, the standard keyboard is not standard, and is widely known as the standard keyboard because of its wide application. Due to the continuous upgrade and update of the software, in order to meet the needs of the software, the number of keys of the so-called standard keyboard is also augmented, and because it is commonly adopted by the industry, it is also known as the standard keyboard in the industry.
