Computer Display Main frame computers are large scale general purpose computers systems. The word main frame has its origin in early computers which were big in size and required large frame work in house. Main frame computers have large storage capacities in several million words. Secondary storage devices are directly accessible by these computers. These computers systems have more than one CPU and can support a large number of terminals. Microcomputer Out Puts for Peripherals Mouse: In computing, a mouse is a pointing device that functions by detecting two-dimensional motion relative to its supporting surface. Physically, a mouse consists of an object held under one of the user's hands, with one or more buttons. Computer Display Graphic Tablet http://www.nwca.com/gdept.asp?dept_id=15. N.p., n.d. Web. 21 Sept. 2012. Display Device Display device is an output device for presentation of information in visual[1] or tactile form (the latter used for example in tactile electronic displays for blind people)[2]. When the input information is supplied as an electrical signal, the display is called an electronic display. Compact Disk: A digitally encoded recording on an optical disk that is smaller than a phonograph record; played back by a laser. Microcomputers mostly handle word processing, spreadsheet calculations, database management, creating or editing photographs or graphics, browsing the Internet, retrieving email and playing music, videos and games. Image scanner Main Frame A minicomputer does not have an extremely large storage area and runs a bit slower than a mainframe. Still, the minicomputer can perform the kinds of tasks a mainframe runs, and at a much lower cost. Small businesses that could not afford a mainframe's cost began using minicomputers. Minicomputers, often called mid range servers, are standalone computer systems supporting more than one terminal or workstation. These multisure systems, serving as many as 200 individual terminals, manage resources on a network, with clients accessing the resources on the server. Minicomputers can process large amounts of data, handle specialized tasks and complex mathematical calculations. Sources http://www.webopedia.com/TERM/M/minicomputer.html. N.p., n.d.

Mini Computer's Computer Mouse Microcomputers are so general that many people do not think two times when they see this machine that has fully modified the way the world works in some decades. The first microcomputers were quite bulky, but microcomputers are now small adequate to carry around. The microcomputer revolution has created our lives easier, but best may be yet to come. Display Device Keyboard DVD: Is a device that plays disc produced under both the DVD-Video and DVD- Audio technical standards Computer Hardware Input for peripherals A monitor or display (also called screen or visual display unit) is an electronic visual display for computers. The monitor comprises the display device, circuitry, and an enclosure. The display device in modern monitors is typically a thin film transistor liquid crystal display (TFT-LCD) thin panel, while older monitors use a cathode ray tube (CRT) about as deep as the screen size.

Graphic Tablet:A graphics tablet or digitizer is a computer input device that enables a user to hand-draw images and graphics, similar to the way a person draws images with a pencil and paper. These tablets may also be used to capture data or handwritten signatures. It can also be used to trace an image from a piece of paper which is taped or otherwise secured to the surface. A computer system that provides storage for one or more host Keyboard: In computing, a keyboard is a typewriter-style device, which uses an arrangement of buttons or keys, to act as mechanical levers or electronic switches. Following the decline of punch cards and paper tape, interaction via teleprinter-style keyboards became the main input device for computers. Hard drive: A high- capacity contained storage device Printer Storage System Printer: In computing, 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. Many printers are primarily used as local peripherals, and are attached by a printer cable or, in most new printers, a USB cable to a computer which serves as a document source. Some printers, commonly known as network printers, have built-in network interfaces, typically wireless or Ethernet based, and can serve as a hard copy device for any user on the network.
