Components of a Desktop Computer (keyboard and Mouse)

Keyboard and Mouse

Most interactions with a computer involve using a keyboard and a mouse. The keyboard allows the user to type letters and numbers and the mouse allows the user to position the cursor, draw and execute program functions by clicking mouse buttons.

Besides basic typing, many other actions can be performed on the keyboard using function keys, cursor keys, control keys or keyboard macros. However, many all these actions are duplicated by mouse use. These days many users choose to operate the computer by mouse rather than using keyboard keys. For good posture, it's important to align the center of your body with the center of the part of the keyboard you use the most, usually either the alphabetic area or the numeric keypad.
