Mouse Usage.....

Many mice today are wireless and use batteries......
On most computers, the user can move the mouse to move the cursor in the same direction.If there is something on the screen that the user wants to choose, he can move the cursor over it and "click" the mouse button. The right mouse button is used to open menus that are different depending on where the cursor is. The other mouse buttons can do different things, depending on the software. A mouse can have 1 to 6 buttons to click, but most mice have two or three. Most mice also have a "scroll wheel" -- a small wheel found between the two main mouse buttons.button.

 The user can move the wheel up or down to "scroll" through things like a website or folder, which means to move it up or down on the screen, or he or she can click the wheel down like another

The usage of mouse is done in many ways .Some of the ways to control and use the mouse is shown below ..

Virtual Network Computing

Control 2 computers from 1 keyboard/mouse on 1 computer with VNC

              In computing, Virtual Network Computing (VNC) is a graphical desktop sharing system that uses the RFB protocol to remotely control another computer. It transmits the keyboard and mouse events from one computer to another, relaying the graphical screen updates back in the other direction, over a network.

                             VNC is platform-independent – a VNC viewer on one operating system may connect to a VNC server on the same or any other operating system. There are clients and servers for many GUI-based operating systems and for Java. Multiple clients may connect to a VNC server at the same time. Popular uses for this technology include remote technical support and accessing files on one's work computer from one's home computer, or vice versa.
                             VNC was originally developed at the Olivetti Research Laboratory in Cambridge, United Kingdom. The original VNC source code and many modern derivatives are open source under the GNU General Public License.
