Mouse development history


The mouse came in its third version as part of the device with the Star Xerox 8010 information system in 1981, and after a while, the mouse spread to personal computers such as the Apple Macintosh and two buttons in the personal computer (PC). Later on, the slide wheel was added, and then the number of buttons increased to three, then it was done. Replace the middle button with a wheel and merge this button with it, and some types now contain more than three buttons and are programmable, and the rest of the buttons are for games applications or graphics and designs.

Screen, which indicates the point at which the user's actions occur, so that the hand movements are repeated by the cursor, like clicking or scrolling (while stopping the movement while the cursor is within the boundaries of the area), can select files, programs or actions from the contacts list.
