Definition Hardware is the physical aspect of a computer. Internal hardware devices include motherboards, hard drives, and RAM.
A computer case is the enclousure that contains most of the components of a computer.
A power supply unit , supplies direct current (DC) power to the other components in a computer. It converts general-purpose alternating current (AC) electric power from the mains to low-voltage DC power for the internal components of the computer.
A motherboard is the central printed circuit board in many modern computers and holds many of the crucial components of the system.
The central processing unit (processor) is the portion of a computer system that carries out the instructions of a computer program, to perform the basic arithmetical, logical, and input/output operations of the system.
Memory (Random Access Memory) is a form of computer data storage. It takes the form of integrated circuits that allow stored data to be accessed in any order with a worst case performance of constant time.
A video card is an expansion card which generates output images to display.
A hard drive is a non-volatile, random access digital magnetic data storage device.
CD ROM Drive is used to read CD ROM discs.
Sound Card is an internal computer expansion card that facilitates the input and output of audio signals to and from a computer under control of computer programs.
Definition Peripherals devices include monitors, keyboards, mouse, printers, and scanners.
A monitor is an electronic visual display for computers.
A keyboard is a typewriter-style keyboard, which uses an arrangement of buttons or keys, to act as mechanical levers or electronic switches.
A mouse is a pointing device that functions by detecting two-dimensional motion relative to its supporting surface.
A printer is a peripheral which produces a text or graphics of documents stored in electronic form, usually on physical print media such as paper or transparencies.
A scanner is a device that optically scans images, printed text, handwriting, or an object, and converts it to a digital image.
Definition Software is a conceptual entity which is a set of computer programs, procedures, and associated documentation concerned with the operation of a data processing system. Examples: Paint, Word, PowerPoint, Photoshop…
