Output Devices
It is a type of printer that does not hit or impact a ribbon to print. They used laser, xerographic, electrostatic, chemical and inkjet technologies. It prints characters and graphics by spraying tiny drops of liquid ink on paper.Example: Laser printer Inkjet printers
An impact printer is a type of printer that operates by striking a metal or plastic head against an ink ribbon.Example: Dot matrix Line printer/Line page printer Ball printers
Non-impact
Printers
Impact
Line page
A line printer is an impact printer which makes use of a continuous feed of paper and prints one line of text at a time.The line printer can Print 300 to 3000 Lines per Minute.
Inkjet
An inkjet printer is a computer peripheral that produces hard copies of a text document or photo by spraying droplets of ink onto paper. A typical inkjet printer can produce color printing copies with a resolution of 1200 x 1440 dpi.
Dot Matrix
A dot matrix printer is an impact printer that prints using a fixed number of pins or wires. Typically the pins or wires are arranged in one or several vertical columns. The pins strike an ink-coated ribbon and force contact between the ribbon and the paper, so that each pin makes a small dot on the paper.
Laser
What is a printer laser? "It is a printer linked to a computer producing good-quality printed material by using a laser to form a pattern of electrostatically charged dots on a light-sensitive drum, which attract toner (or dry ink powder). The toner is transferred to a piece of paper and fixed by a heating process."
Plotter
A plotter printer is a printing device mainly used for producing vector graphics or vector images, which are images made up of paths or lines with starting and ending points.Instead of toner, plotters use a pen, pencil, marker, or another writing tool to draw multiple, continuous lines onto paper rather than a series of dots like a traditional printer.
Monitors
A monitor is a piece of computer hardware that displays information in pictorial form.
The Cathode Ray Tube (CRT) monitor is one kind of display unit used mainly for computers and television. Itcontains millions of tiny red, green, and blue phosphor dots that glow when struck by an electron beam that travels across the screen to create a visible image.
CRT
A liquid crystal display (LCD) monitor is a computer monitor or display that uses LCD technology to show clear images, and is found mostly in laptop computers and flat panel monitors.
LCD
HeadphonesHeadphones are a pair of small loudspeaker drivers worn on or around the head over a user's ears. They allow you to listen to audio or watch a movie without disturbing people around you. They are electroacoustic transducers, which convert an electrical signal to a corresponding sound.
SpeakersSpeakers are output devices that produce sound. They are transducers that convert electromagnetic waves into sound waves. Speakers receive audio input from a device such as a computer or an audio receiver.
Speaker/Headphones
Multimedia Projector
Using a multimedia projector, you can show a DVD, video, slide show or television program on a large screen with color and sound.Multimedia projectors can be connected to computers, VCRs, DVD players and cable boxes. The images transmitted from the device are then transmitted into a special digitized light that is reflected on thousands of mirrors within the projector, which shines the image onto a screen.
