Types of Mouse:
A Mouse can be classified in several ways. According to the working mechanism a mouse can be three types :
1. Mechanical Mouse: A hard rubber ball that rolls as the mouse is moved. Sensors inside the mouse body detect the movement and translate it into information that the computer interprets.
2. Optical Mouse : It uses an LED (Light Emitting Diode) sensor to detect laptop movement and then sends off that information to the computer for merry munching.
3. Opto mechanical Mouse : This is same as the mechanical Mouse except that it uses optical sensors to the motion of ball. It demands a mouse pad under the mouse to run.
A mouse can be three type according to how a computer mouse hooks up or connects to the computer:
1. Serial Mouse: This type of mouse comes with a serial connector. It requires a free serial port on our personal computer.
2. PS/2( Personal System/2) Mouse or wheel Mouse :Uses Infrared signals to connect to the computers IrDA pot; it must be within sight of the receiving port.
3. Cordless Mouse : A cordless mouse free from cord(wire) problem. It connects to our computer with a radio signal. We can also say that Wireless Mouse.
Types of Scanner :
1). Drum Scanner : It use a rotating drum to scan loose paper sheets.
2). Flatbed Scanner : They have movable sensors to scan images placed on a flat glass tray.
3). Hand Held Scanner : They are cheaper, small in size, good hand control, and high quality scanning.
4). Video Scanner : They use video technology and video cameras instead of scanning technology.
