Is a disk drive that uses laser light or electromagnetic waves within or near the visible light spectrum as part of the process of reading or writing data to or from optical discs

Is a form of computer data storage that stores data and machine code currently being used

Is the electronic circuitry within a computer that carries out the instructions of a computer program by performing the basic arithmetic, logical, control and input/output (I/O) operations specified by the instructions.

Is the main printed circuit board (PCB) found in general purpose microcomputers and other expandable systems. It holds and allows communication between many of the crucial electronic components of a system

Is an electrical device that supplies electric power to an electrical load. The primary function of a power supply is to convert electric current from a source to the correct voltage, current, and frequency to power the load.

Fans attached to components are usually used in combination with a heat sink to increase the area of heated surface in contact with the air, thereby improving the efficiency of cooling.

Is an internal expansion card that provides input and output of audio signals to and from a computer under control of computer programs.

Is an expansion card which generates a feed of output images to a display. Frequently, these are advertised as discrete or dedicated graphics cards, emphasizing the distinction between these and integrated graphics.

Is an electronic device that connects a computer to a computer Network, usually a LAN.

Is a hand-held pointing device 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.

A device that projects an enlarged image of an acetate or other transparency placed on it on to a wall or screen.

Is a peripheral device which makes a persistent human-readable representation of graphics or text on paper.

A device that converts analog audio signals into the equivalent air vibrations in order to make audible sound.

Is a device that captures images from photographic prints, posters, magazine pages, and similar sources for computer editing and display.

A video camera connected to a computer, allowing its images to be seen by Internet users.

A machine allowing the creation of a physical object from a three-dimensional digital model, typically by laying down many thin layers of a material in succession.

Is a device that analyses a real-world object or environment to collect data on its shape and possibly its appearance. The collected data can then be used to construct digital three-dimensional models.
