And the keyboard can also be interpreted as computer hardware in the form of a board and has various kinds of buttons where the functions of the buttons vary depending on the emphasis which can produce processes that are in accordance with the wishes of the user. Not only as a tool for inputting data, but the keyboard also has a variety of key functions with special combinations.

Keyboard Functions
In general, the function of the keyboard on a computer is to send commands from each letter, number, and symbol that is typed and then convey it to the Central Processing Unit (CPU), then the command is converted into digital symbols so that the command can be understood by the processor.
Keyboard Key Arrangement

It was the first keyboard to have the letters A to Z, punctuation marks, and numbers 1–0 used to enter text into a computer system, for example when typing in Microsoft Office or in an internet browser.
Directional Keys
These four buttons are marked with arrow characters that point on all four sides. This button functions to move the cursor and screen in the desired direction.
Numeric/ Directional Keypad
is a button that contains numbers and a cursor move button which is usually located on the right side of the main typing board. The key will only work when the Numeric key function key is turned on. These keys can make it easier for you to type and enter numbers into the system.

The button is above the main typing keypad and can be seen from symbols F1 to F12. These buttons function to set several commands, such as saving documents, showing the help menu when typing in Microsoft Word, and so on.
Special Keys
The Special Keys are at the top of the directional keys which consist of the Home, Delete, Page up, Page Down, Insert, Print screen, pause break, and End buttons.
