Which of the following is/are Output Device?

The correct answer is All of these.

Key Points

• Output devices are hardware components that convey information from a computer to the user in a perceivable form.
• A Projector is an output device that projects visual information onto a surface, such as a screen or wall, for display purposes.
• A LED Monitor is a flat-panel display technology that provides visuals as output from the computer, commonly used for video display.
• Printers are output devices that produce physical copies of digital documents, images, or text on paper.
• All the mentioned devices (Projector, LED Monitor, and Printer) qualify as output devices, as they deliver processed data from the computer to the user.

Additional Information

• Output Device Definition: Output devices are peripherals used to communicate the results of data processing carried out by a computer to the user or another device.
• Types of Output Devices: Output devices can be categorized into visual output (e.g., monitors, projectors), audio output (e.g., speakers, headphones), and physical output (e.g., printers).
• Examples of Other Output Devices: Common examples include speakers for audio output, plotters for large-scale printing, and haptic devices for tactile feedback.
• Contrast with Input Devices: Input devices (e.g., keyboards, mice) send data to a computer, while output devices receive and present data from the computer.
• Advancements in Output Technology: Modern output devices, such as 4K monitors and 3D printers, provide high-resolution visuals and advanced functionality, enhancing user experience.
