Output Devices Definition: What Are Output Devices in Computer?
An output device is any hardware component of a computer that receives data from the computer system and converts it into a human-readable or usable form. In simpler words, output devices take the processed information from the computer and present it to the user in a form they can see, hear, or physically hold.
The word ‘output’ itself means the result or product of a process. When you type a document and print it, the printer is converting the computer’s digital data into a physical paper printout. When you play a video, your monitor is converting digital signals into visible moving images. Both are output devices performing their core function.
In Hindi, output devices are called Nairgam Upkaran (निर्गम उपकरण) or Output Dvices (आउटपुट डिवाइस). Both terms are used in SSC bilingual question papers.
| Aspect | Detail |
| Definition | Hardware that receives processed data from the computer and presents it to the user |
| Hindi Name | आउटपुट डिवाइस / निर्गम उपकरण |
| Direction of Data | From the computer TO the user (computer → device → user) |
| Type | External Hardware Component |
| Examples | Monitor, Printer, Speaker, Plotter, Projector, Headphone |
| Opposite of | Input Devices (which send data FROM user TO computer) |
Input Devices vs Output Devices: Key Differences (Most Tested in SSC)
One of the most commonly asked questions in SSC Computer Awareness is the distinction between input devices and output devices. Many students confuse them under pressure. Here is a crystal-clear comparison table:
| Feature | Input Devices | Output Devices |
| Function | Send data FROM user TO computer | Send data FROM computer TO user |
| Direction | User to Computer | Computer to User |
| Data Flow | Inward (into the system) | Outward (out of the system) |
| Examples | Keyboard, Mouse, Scanner, Microphone, Webcam, Joystick | Monitor, Printer, Speaker, Projector, Plotter, Headphone |
| What it produces | Input (raw data for processing) | Output (processed, usable result) |
| Hindi Name | इनपुट डिवाइस / आगत उपकरण | आउटपुट डिवाइस / निर्गम उपकरण |
| User Interaction | User controls input device to give commands | User views, hears, or receives results from output device |
Devices That Are Both Input and Output (I/O Devices)
Some devices serve both as input and output, depending on how they are being used at a given moment. These are called Input/Output devices or I/O devices. Knowing these is important because SSC exams sometimes ask which devices function as both:
| Device | As Input | As Output |
| Touch Screen | User touches screen to give input | Screen displays visual output |
| Headset with Microphone | Microphone captures voice (input) | Earphones play audio (output) |
| Modem | Receives data from the internet | Sends data to the internet |
| Network Interface Card (NIC) | Receives data from the network | Sends data to the network |
| External Hard Drive | Computer reads data from it | Computer writes data to it |
| CD/DVD Drive (Read/Write) | Reads data from disc (input) | Writes data to disc (output) |
| USB Flash Drive | Computer reads data from it | Computer writes data to it |
Types of Output Devices: Complete Classification with Examples
Output devices are classified based on the type of output they produce. For SSC exams, knowing the classification of output devices with examples is extremely important. Here is the complete breakdown:
| Type of Output | Output Form | Output Device Examples |
| Hardcopy Output | Physical, permanent output you can touch and hold | Printer (Inkjet, Laser, Dot Matrix), Plotter |
| Softcopy Output | Temporary, digital output displayed on screen or as audio | Monitor, Projector, Speaker, Headphone |

| Pixel | Picture Element | Smallest unit of a digital image on screen |
| Screen Size | Diagonal measurement in inches | Measured diagonally from corner to corner of screen |
Types of Printers: Most Important Output Device Topic for SSC
Printers are the most tested subcategory within output devices in SSC exams. You absolutely must know all types of printers, their working principles, and their differences. Here is the most comprehensive printer reference table for your SSC preparation:
Impact vs Non-Impact Printers: The Primary Classification
| Category | How It Works | Examples | Key Feature |
| Impact Printer | A physical mechanism (pins, hammers, or type head) strikes an ink ribbon against paper to create characters | Dot Matrix Printer, Daisy Wheel Printer, Line Printer | Can create carbon copies; noisy operation; used where multi-part forms are needed |
| Non-Impact Printer | Does not physically strike paper; uses heat, laser, or inkjet technology to create output | Inkjet Printer, Laser Printer, Thermal Printer, 3D Printer | Silent operation; better print quality; cannot create carbon copies directly |
Detailed Printer Types Comparison Table
| Printer Type | Category | Technology Used | Print Quality | Speed | Cost | Best Use |
| Dot Matrix | Impact | Pins strike ink ribbon on paper to form characters | Low (visible dots) | Slow | Low | Bank passbooks, railway tickets, multi-part invoices |
| Daisy Wheel | Impact | Rotating wheel with character shapes struck against ribbon | High (typewriter quality) | Very Slow | Moderate | Word processing in early computers (now obsolete) |
| Line Printer | Impact | Prints entire line at once using rotating drum or chain | Low-Medium | Very Fast | High | Large volume batch printing in mainframe computers |
| Inkjet Printer | Non-Impact | Tiny nozzles spray liquid ink droplets on paper | High (especially color) | Moderate | Low to Moderate | Home use, photo printing, color documents |
| Laser Printer | Non-Impact | Laser beam draws image on drum; toner powder fused by heat | Very High | Fast | Moderate to High | Office bulk printing, professional documents |
| Thermal Printer | Non-Impact | Heat applied to heat-sensitive paper to form image | Moderate | Fast | Low | ATM receipts, billing counters, POS systems |
| 3D Printer | Non-Impact | Deposits material layer by layer to create 3D objects | High (3D objects) | Very Slow | Very High | Prototyping, manufacturing, medical models |
| Plotter | Non-Impact | Pens or inkjet heads draw precise lines on large paper | Very High (line art) | Slow | High | Engineering drawings, architectural plans, maps |
| LED Printer | Non-Impact | Like laser but uses LED array instead of laser beam | Very High | Fast | Moderate to High | Office printing; similar use cases to laser printer |
DPI: What Does Print Resolution Mean?
DPI stands for Dots Per Inch. It measures the resolution or quality of a printer’s output. A higher DPI means more dots are packed into each inch, resulting in a sharper and more detailed printout. For example, a standard office laser printer typically prints at 600 DPI, while high-quality photo printers can print at 1200 DPI or higher.
Speakers and Audio Output Devices: Notes for SSC
Audio output devices convert digital audio signals from the computer into sound waves that humans can hear. These are output devices that produce sound-based output. Here is a complete overview:
| Audio Output Device | Working Principle | Use Case |
| Speaker | Converts electrical signals into sound waves using a diaphragm and electromagnet | Desktop and laptop audio, music, system alerts, video playback |
| Headphone | Same as speaker but worn over or in the ears for personal audio | Private listening, calls, gaming, music |
| Earphone / Earbuds | Smaller version of headphone; fits inside the ear canal | Mobile audio, commuting, compact personal audio |
| Sound Bar | Elongated speaker unit with multiple drivers for enhanced audio | TV audio, home theater, multimedia presentations |
| Subwoofer | Specialized speaker for low-frequency bass sounds | Music systems, gaming audio, home theater |
Projector: Definition, Types, and SSC Exam Notes
A projector is an output device that takes the video signal from a computer and projects an enlarged image onto a screen or flat surface. Projectors are widely used in classrooms, conference rooms, movie theaters, and presentations.
| Projector Type | Technology | Best For | Key Feature |
| LCD Projector | Liquid Crystal Display panels split light into RGB and project it | Classrooms, business presentations | Accurate colors, good brightness |
| DLP Projector | Digital Light Processing using micro-mirrors on a chip | Home theater, portable projectors | Sharp images, high contrast, minimal maintenance |

| Laser Projector | Laser light source for projection | Large venues, auditoriums | Extremely bright, long life, instant on/off |
| LCOS Projector | Liquid Crystal on Silicon – combines LCD and DLP | Home cinema, high-end use | Very high resolution, smooth images |
Plotter: Definition, Types, and Use in SSC Notes
A plotter is a specialized output device used to produce large-format, high-precision graphical output on paper or other media. Unlike regular printers that print text and images on A4 or letter-size paper, plotters are designed to handle very large sheets and produce accurate technical drawings.
Plotters are commonly used by architects, civil engineers, mechanical engineers, and graphic designers to print blueprints, technical diagrams, maps, and detailed design drawings.
| Plotter Type | Working Principle | Use Case |
| Drum Plotter | Paper is wrapped around a rotating drum; pens move horizontally to draw | Large engineering drawings; paper moves, pens move sideways |
| Flatbed Plotter | Paper lies flat; pens move in both X and Y directions over the paper | Precise drawings; paper stays still, entire surface accessible |
| Inkjet Plotter | Uses inkjet technology on wide-format rolls instead of pen | Banners, posters, architectural plans, GIS maps |
| Cutting Plotter | Uses a blade instead of a pen to cut shapes from vinyl or paper | Signage, stickers, vinyl graphics, fashion cutting |
Braille Printer / Embosser: Accessibility Output Device
A Braille printer, also called a Braille embosser, is a specialized output device that converts digital text into Braille, which is a tactile writing system used by people who are visually impaired. Instead of printing with ink, it embosses (raises) dot patterns onto thick paper that the reader can feel with their fingertips.
In SSC exams, Braille printers are sometimes asked in the context of accessibility devices or tactile output devices. Knowing that Braille printers produce tactile output (output perceived through touch) differentiates them from all other output devices.

(FAQs)
Q1. What are output devices in computer with examples?
Output devices are hardware components that receive processed data from the computer and present it to the user. Examples include Monitor (visual output), Printer (printed output), Speaker (audio output), Projector (visual presentation), Plotter (large-format drawings), and Braille Printer (tactile output for visually impaired users).
Q2. What is the difference between hardcopy and softcopy output devices?
Hardcopy output is physical and permanent, meaning it exists even after the computer is switched off. Examples are Printer and Plotter outputs. Softcopy output is temporary and digital, existing only while the device is running. Examples are Monitor display and Speaker audio.
Q3. Which printer is an impact printer?
Dot Matrix Printer, Daisy Wheel Printer, and Line Printer are all impact printers. They work by physically striking an ink ribbon against paper. Dot Matrix is the most commonly tested impact printer in SSC exams because it is still used in banks, railways, and government offices for carbon copy printing.
Q4. What is VDU in computer output devices?
VDU stands for Visual Display Unit. It is another name for a computer monitor. The VDU displays text, images, and video output from the computer. It is a softcopy output device because the display is temporary and disappears when the monitor is turned off.
Q5. Is a speaker an output device?
Yes, a speaker is an output device. It receives digital audio signals from the computer’s sound card and converts them into sound waves. Since it presents processed information (audio) to the user, it is classified as an output device. More specifically, it is an audio output device that produces softcopy output.
Q6. What is a plotter and how is it different from a printer?
A plotter is an output device used to produce large-format, high-precision drawings on paper or other media. Unlike regular printers that print on standard A4 or letter-size paper, plotters are designed for very large sheets and are used by engineers and architects for blueprints, technical drawings, and maps.
