Basic Element of Electronics Data Processing Hardware Hardware Software Software Networking Networking Person involved in Computer Fields Person involved in Computer Fields Hardware The physical elements of computer are known is called hardware. 1.Input Devices 2.Output Devices 3.C.P.U 4.Storage devices
Output Devices An output device is any device used to send data from a computer to another device. electronic or electromechanical equipment connected to a computer and used to transfer data out of the computer in the form of text, images, sounds, or other media. Monitor/CRT It is General-purpose color cathode ray tube (CRT) monitors are used commonly for image display in personal computer-based picture archiving and communication system (PACS) and telemedicine systems. Printer A hard copy is a printed copy of information from a computer. You get print out on paper from computer. There are two types of printer 1)Impact printer 2)Non Impact printer
Impact Printer a printer that prints by mechanical impacts. a printing device in which a printing element directly strikes a surface (as in a typewriter). It uses a print head that hits the surface of the ink ribbon. Non Impact Printer Non-impact printer is a type of printer that does not operate by striking a head against a ribbon. For example, Laser printers and ink- jet printers are non-impact printers.
Speaker /Head Phone Speakers/Head phone are one of the most common output devices used with computer systems. Speakers/Head Phone are transducers that convert electromagnetic waves into sound waves. The speakers receive audio input from a device such as a computer or an audio receiver.,
