What is a computer mouse?

A computer mouse is an input device that is used by clicking and scrolling. A basic mouse has a left button, right button and a scroll button.

Two main types of a computer mouse

  • Mechanical mouse
  • Optical mouse

Mechanical mouse

This type of mouse has a small plastic/metal ball in a socket under it which rolls as the mouse moves. The rolling of the small ball gives the sensor in the mouse the direction in which the cursor/pointer should be moved.

Optical mouse

This type of mouse uses light-emitting diode(LED) to detect its movement . The sensor picks the signal and uses it to move the pointer. An optical mouse may have a cord or  may not. The one without a cord is called wireless/cordless mouse.

    I have discovered some new issues from your site about pc’s. Another thing I have always thought is that computer systems have become an item that each house must have for some reasons. They offer convenient ways in which to organize the home, pay bills, shop, study, listen to music and also watch tv programs. An innovative approach to complete every one of these tasks is with a laptop computer. These desktops are mobile, small, robust and portable.
