Talking about the keyboard, the keyboard is the main input device of the computer. Because through this, we can enter various commands to the computer, work with documents, and perform various functions. Let's study its structure.
Figure 1. Division of keys into functional groups depending on their function
Key controllers - this key group is used to perform a specific task when used separately or with other keys; Functional keyboards — these keys are used for specific issues. They have specific names such as F1, F2, F3 and up to F12; Input keyboards — this key group consists of letters, numbers, symbols. It is the main part of the keyboard; Conductive keyboards — the function of these keys is used for editing and viewing web pages or word documents, moving up-down, right-left, beginning-end, and similar functions; Numeric keyboards — used for faster work with numbers; Indicators — tells about the status of the keyboard, that is (from left to right) and when indicator 1 lights up, it means that we are using uppercase letters for writing (for information, uppercase letters (QWERTY) and lowercase letters (qwert), to enable this, press "Shift" on the keyboard key is used), when the 2nd indicator is lit, it means that we can use the numeric keypad (to enable this, we use the "Num Lock"), the 3rd indicator indicates that the "Scroll Lock" is lit, that is, in the usual case, the transfer keyboard up, down, the left and right keys move the cursor one by one, and when "Scroll Lock" is on, the cursor stays in place, but the page itself starts to move up, down and to both sides.
