A communication device is a peripherical used for communication between the computers and other devices. Modem is a popular communication device which is normally used for internet communication. Infra red, Bluetooth and LAN card are the examples of communication devices. Examples of communicacion devices are: • Modem: Modulator/demodulator Temas Relacionados: An input/output device is also known as storage device. These computer devices preserve information for retrieval. In other words, an storage device is capable of storing data. The term usually refers to mass storage devices, such as disk and tape drives. There are two types of storage devices used in computers; a ‘primary storage’ device and a ’secondary storage’ device. Primary storage device An output device is any peripheral that is connected to a computer and used to transfer data out of the computer in the form of text, images, sounds or other media to a display screen, printer, loudspeaker, or storage device. Examples of output devices are: Electronic output devices can be mechanical, audio, or visual. Mechanical outputs include motors, solenoids, and other electromagnetic devices.... A computer system may consist of several devices. Every device has its own functionality. We need these devices to work properly with computer. We can divide these devices into following types. Input devices: An input device is used to provide data to computer for processing or storing. There are different types of input devices. Keyboard, mouse, scanner, light pen and barcode reader and card reader are the examples. All input devices are connected with the CPU. Different signals are generated... A “peripheral device” or “computer device” is a hardware component that is attached to a computer in order to expand its abilities and performing additional features. Computers are able to interact with its external world using the peripherals as mice, monitors, plotters, keyboards, and printers. Peripheral means “additional but not essential”, so peripherals are not part of the essential computer as are the processor, and the memory. Some peripherals are mounted in the same case with the main part of the computer as are... The computer mouse was invented by the Dr. Douglas Engelbart. He first demonstrated the device called, at the time, an “X-Y Position Indicator for a Display System” at a computer conference in San Francisco in 1968. Engelbart made a small, brick-like mechanism with one button on top and two wheels on the underside. The two wheels detected horizontal and vertical movement, and the unit was somewhat difficult to maneuver. The unit was linked to the computer by a cable so the motion signals could be electrically transmitted to the computer for viewing on the monitor. By 1973,...
