MOUSE
A mouse is a hand-held device that controls the movement of a pointer on your screen or a mouse is an input device. You use your mouse to perform task on your computer. As you move the mouse, a mouse pointer moves on your screen. When you position the pointer over an object, you can press (click or double-click) the mouse button to perform different action on the object. For example, you can Click to select files, Double-click to open and Click-and Drag to move files. In fact, you’ll probably use your mouse for most tasks. The pointer usually appears as an arrow. But it can change shape depending on where it finds itself.
Computer Mouse Connection types
There are two types of mouse connectors, Serial and PS/2. Earlier computers tend to have the Serial connector while more recently made ones have a smaller 6 pin PS/2 socket. Check the picture above to find yours.
Please note that there are many mice that use the USB type of connection not shown above. Always check you have a USB connection on your computer before purchasing a USB type mouse

PS/2 Port
A type of port developed by IBM for connecting a mouse or keyboard to a PC. The PS/2 port supports a mini DIN plug containing just 6 pins. Most PCs have a PS/2 port so that the serial port can be used by another device, such as a modem. The PS/2 port is often called the mouse port.
Serial Port
A port, or interface, that can be used for serial communication, in which only 1 bit is transmitted at a time.
Most serial ports on personal computers conform to the RS-232C or RS-422 standards. A serial port is a general-purpose interface that can be used for almost any type of device, including modems, mice, and printers (although most printers are connected to a parallel port).

Types of Mouse
A mouse is a pointing device used to interact with a PC; there are a few different types of mouse available.
Serial Mouse - This is a mouse with a serial connector, it requires a free serial port on your PC. USB Mouse - This type of mouse has a USB connector and requires a free USB port. Cordless Mouse - A cordless mouse (as the name suggests) has no cable, this type of mouse utilises batteries for its power supply. Optical Mouse - An optical mouse utilises optical electronics to track the mouse's position and movement, they are preferred over standard mechanical mice as they tend to be more reliable and require less maintenance. |
