What is Output Devies?
An output device is a hardware component that receives processed data from a computer and converts it into a human-understandable form, such as visual (monitor, projector), audio (speakers, headphones), or physical (printer) output, allowing users to perceive and interact with the results of computer

1. CRT (Cathod Ray Tube)
1. CRT (Cathod Ray Tube)
A CRT (Cathode Ray Tube) monitor is an older, bulky display technology that creates images using an electron gun firing beams at a phosphorescent screen inside a vacuum tube
2. LCD (Liquid Crystal Display)
2. LCD (Liquid Crystal Display)
LCD stands for Liquid Crystal Display, a flat-panel technology using liquid crystals to modulate light, common in TVs, monitors, and phones, creating images by controlling light passage with an electric current, unlike LEDs that emit their own light, requiring a backlight but offering low power and thin designs
3. Speaker
3. Speaker
A speaker output device converts electrical signals from a computer or audio device into audible sound waves, allowing users to hear audio like music, system sounds, and videos
4. Projector
4. Projector
A projector is an optical device that takes an image or video from a source (like a computer, Blu-ray player, or streaming device) and projects it onto a large surface, such as a screen or wall, creating a magnified, viewable display using light and lenses

1. Dot Matrix Printer
1. Dot Matrix Printer
A dot matrix printer is an impact printer that creates text and images by striking a print head of pins against an inked ribbon, transferring ink in a pattern of dots onto paper, forming characters from a "matrix" of dots
2. Laser Printer
2. Laser Printer
A laser printer is a high-speed, non-impact printer that uses a laser beam to draw images or text onto a photosensitive drum, which then attracts toner and transfers it to paper via heat
3. Inject Printer
3. Inject Printer
A thermal printer uses heat to create images or text on special paper, eliminating the need for ink or toner by activating heat-sensitive chemicals in the paper or transferring ink from a ribbon onto the media
4. Thermal Printer
4. Thermal Printer
A thermal printer uses heat to create images or text on special paper, eliminating the need for ink or toner by activating heat-sensitive chemicals in the paper or transferring ink from a ribbon onto the media
5. Plotter Printer
5. Plotter Printer
A plotter is a specialized computer output device that creates high-quality, large-scale vector graphics, like architectural plans, maps, and engineering drawings, by drawing continuous lines with automated pens or other tools, unlike standard printers that use dots for raster images
6. Line Printer
6. Line Printer
A line printer is a high-speed impact printer that prints an entire line of text at once, rather than character by character, making it very fast for large-scale tasks like printing reports and invoices
