Wha is computer Mouse?

Douglas Engelbart invented the computer mouse in 1963. It is a device that enables a computer user to move the cursor or pointer to a specific point on the screen.  it is named so because the appearance and movement are very similar to that of the mouse. When you move the mouse, the cursor on the screen also moves the mouse, the cursor on the screen also moves in the same direction.
               A mouse can have two or three buttons, each of which does a different function. Modern Mice also include a Scroll button that makes it easier to read long Documents. The mouse is the most used input device later the keyboard. The usage of the mouse greatly reduces the extent the usage of the keyboard. The mouse is particularly important for graphics User Interface (GUI) applications, wherein you point to an option or object on the screen and click the appropriate mouse button. You can also the mouse for drawing objects on the screen by using the mouse as a pencil or paintbrush.
Identifying Different types of mice

To identify different types of mice we need to check the following things

  • Working
  • Interface

Types of Mouse

Working off a mouse depends on how the cursor moves on the screen either by using mechanical assembly or by using a light signal.
A mouse that uses mechanical assembly to move the cursor on the computer screen are called mechanical mouse and mice that use optical (light) signal to move the cursor on the screen are called optical mouse.

Mechanical Mice

A mechanical mouse translates motion into directional signals using mechanical components. It has a ball and a couple of rollers. By the help of these mechanisms, the cursor moves on the screen. As there is present a moving part i.e. mouse ball and it physically touches with the roller so the cursor movement is not so accurate. More Dust is accumulated on the rollers as the mouse ball pick up the dust from the surface and transfers the same to the rollers. So, it is necessary to clean the mechanical mouse on a regular interval for smooth operation.

Optical Mouse

An optical mouse uses LED technology to detect the movement of the mouse. It is the most accurate and precise type of mouse. The optical mouse has no moving parts and uses camera technology and digital processing to compare and track the position of the mouse rathe r than a ball and rollers used on older mice.
As there no moving parts in optical mice, almost no maintenance or regular cleaning is required. Another advantage is that digital processing often results in smoother, more exact performance than previous technologies. Optical mice usually don’t need a mouse pad and can be used on many surfaces, including those that are not entirely flat.

Laser-based Optical Mouse

 A technology has recently emerged piggybacking off of the LED optical mouse. The Laser-based optical mouse work similar to the LED-based optical mouse. It uses a laser instead of LED. The benefit is that because it uses a laser beam, the mouse can track much better, giving the user ultimately better responses times tracking and the ability to be used on more surfaces.
