a surface. This motion is typically translated into the motion of a pointerdevice that detects two-dimensional motion relative to a surface. This motion is typically translated into the motion of a pointer on a displaydevice that detects two-dimensional motion relative to a surface. This motion is typically translated into the motion of a pointer on a display, which allows a smooth control of the graphical user interfacedevice that detects two-dimensional motion relative to a surface. This motion is typically translated into the motion of a pointer on a display, which allows a smooth control of the graphical user interface of a computer.
The first public demonstration of a mouse controlling a computer system was in 1968. Mice originally used two separate wheels to track movement across a surface; one in the X-dimension, and one in the Y. Later, the standard design shifted to utilise a ball rolling on a surface to detect motion. Most modern mice use optical sensors that have no moving parts. Though originally all mice were connected to a computer by a cable, some modern mice are cordless, relying on short-range radio communication with the connected system.

involved in computer processing. In a computer system, the microprocessor is the central unit that executes and manages the logical instructions passed to it. A microprocessor may also be called a processor or central processing unit, but it is actually more advanced in terms of architectural design and is built over a silicon microchip.

of hardware for a computer. It allows a user to print items on paper is a piece of hardware for a computer. It allows a user to print items on paper, such as letters and pictures. Mostly a printer prints under the control of a computer. Many can also work as a copying machine or with a digital camera to print directly without using a computer.
