Mouse is an important supporting device of a computer, which performs as an input unit to feed data. The usage of mouse is essential to control the mouse pointer. Users need mouse not only to feed inputs but also to navigate between menus, to draw images, to choose a function, to open or close a file etc. If you work in MS-DOS platform, you may not require the mouse. Some of the mouse operations have been explained in this article.

• Clicking
The very first function of a mouse is clicking. It can be done by just pressing the left button of the mouse only once. This function is needed for selecting a particular menu or item.

• Double clicking
This double clicking is as same as clicking. The difference is users have to press the left mouse button twice quickly. The clicks should be fast and consecutive. If you leave more gaps between the two clicks, this double clicking will not work properly. This operation is needed for opening or activating a function.

• Right clicking
When right button of the mouse is clicked, it is called as 'right clicking'. This right clicking function will be demanded while you work in Windows. Right click may be needed to open pop-up menus. You can use these right clicks for cutting, copying, pasting etc.

Mouse Connectivity and its types

Connectivity means nothing but giving connection from the mouse to the computer. There are 3 different connectors used for connecting the mouse namely:

• Serial Connector
This is one of the oldest methods of connecting the mouse and it has been outdated. It is very rare to see a mouse with this type of serial connector now.

• PS/2 Connector
This type of connector uses a tiny plug which is rounded in shape.

• USB Connector
It is the latest connector type in which small rectangular ports are used. Normally a mouse has 2 ports. This type of 'Universal Serial Bus' connectivity offers high speed data transfer. The unique advantage of this connector is hot swappable. It is nothing but the users can unplug or plug USB units though the PC is running. There is no need to shutdown to plug or unplug it.
