Keyboard is an indispensable input device in a computer. Users can input commands, programs and data through the keyboard and control the operation of the computer through it. It can be divided into four types: mechanical, capacitive, thin film and conductive rubber.

Most of the common keyboards are 10 1 or 104. Some relatively novel 104 keyboards often have two Windows keys and an application key to improve the efficiency of operating computers on Windows 10 operating system. These keys can be divided into a large keyboard area, an editing keyboard area, a function key area and a small keyboard area.

There are sixty-one keys in the keyboard area * * *. The arrangement of these keys is the same as the layout of the standard English typewriter, and there is no logical connection. They include 26 letters, numbers 10, common punctuation marks, space bar and individual computer-specific keys, which are used to input characters, numbers and symbols and issue various commands to the computer. These keys are often used in large numbers.

The function key area is located at the top left of the keyboard. * * * has twelve keys marked with F 1 to F 12, which will give them different functions in different applications, so to understand their uses, you must first understand the software you use before you can use them. Press F 1 to open the help for the application. The edit keypad is located in the middle of the right side of the keyboard. There are ten keys in * * *, which are used to control the page turning and movement of the cursor, as well as the insertion and deletion of text.

The keypad area is the seventeen keys on the far right of the keyboard, including numbers (from 0 to 9), decimal points and four operation symbols. These keys are very useful and are often used to enter numbers quickly. ? There are also three keys on the right side of the upper left function key: screen print key, scroll lock key and pause key. They all have special purposes, which requires us to pay more attention when using Windows 10 operating system. ? There are three types of keyboard interfaces: AT interface, PS/2 interface and USB interface, which can be connected with the corresponding interface on the motherboard. When connecting, it is only necessary to correspond according to the shape and color of the interface, and it is generally not wrong.

At present, many keyboards are designed according to ergonomic principles.
