I believe there must be some friends who have used computers for n years, and they are not familiar with some keyboard keys. Here I mainly explain the keyboard layout and function keys of the computer, and welcome everyone to refer to and learn.

Cognitive keyboard

The keyboard is the input device of the computer. Through the keyboard, you can input information to the computer, including instructions, data and programs. The keyboard consists of a set of key switches in matrix mode. According to the different key principles, keyboards can be divided into contact keys and capacitive keys; There are 83, 10 1, 102, 104 key keyboards. We usually refer to the commonly used 10 1 keyboard as a standard keyboard. At present, the commonly used keyboard adds three Windows operation keys to the 10 1 key. Some keyboards also add wake-up keys, sleep-to-sleep keys and power management keys.

Keyboard layout:

The keyboard is mainly divided into four zones: main keyboard zone, function key zone, editing key zone and numeric key zone.

Main keyboard area-located on the left side of the keyboard, each key is marked with English letters, numbers and symbols, with a total of 62 keys, of which 3 keys are used for Windows operation. The main keyboard is divided into letter keys, numeric keys, symbol keys and control keys. This area is the most commonly used keyboard area when we operate the computer.

Function key area-mainly distributed in the top row of the keyboard, from F 1 to F 12. In different software, function keys can be defined, and they can also be defined together with other keys to play different roles.

Edit Keyboard-Located on the right side of the main keyboard area, it consists of 10 keys. It has a special control function in text editing.

Numeric keypad-located at the far right of the keyboard, also known as keypad. The keyboard has the functions of numeric keys and editing keys.
