Output Devices Quiz Questions And Answers

Plotters are specialized output devices commonly used in architectural, engineering, and design fields to produce large-scale drawings with precise details. Unlike printers, which print images pixel by pixel, plotters use pens or markers to draw continuous lines based on vector graphics, enabling accurate rendering of complex diagrams and plans.

A pixel is the smallest unit of an output device display. It refers to a single point in a graphic image, which can be illuminated or colored to form a complete picture. Pixels are arranged in a grid pattern on a display screen, such as a monitor, and each pixel can be individually controlled to create images or text. Therefore, the correct answer is Pixel.

The term "hard copy" refers to a physical, printed version of a document or file. It is the type of output that is printed on permanent media such as paper or other materials. In contrast, a "soft copy" refers to an electronic version of a document that is displayed on a screen and is not physically printed. Therefore, the correct answer is "Hard Copy" as it represents the type of output that is printed on permanent media.

A device that records images of text or converts printed text into machine-readable form is called a scanner. Scanners are commonly used to digitize physical documents and convert them into electronic files. They capture the text and images on the document and convert them into a digital format that can be stored, edited, and shared electronically. Scanners are widely used in offices, libraries, and other settings where physical documents need to be converted into digital form for various purposes.

A plotter is a specialized output device that is used for producing charts, maps, and very high-quality drawings. Unlike printers, which use ink or toner to create images on paper, plotters use pens or other drawing tools to physically draw the images on the paper. This allows for more precise and detailed drawings, making them ideal for applications that require high-quality visuals, such as engineering or architectural designs. Scanners, on the other hand, are input devices used to convert physical documents or images into digital files, while imagers are not specifically designed for producing charts, maps, or drawings.

Ink-jet printers are known for their ability to produce high-quality prints and are generally less expensive than laser printers. However, the cost-effectiveness can depend on the usage and the cost of ink cartridges. Please note that understanding the principles of computer hardware, such as different types of printers, is crucial for making informed decisions. Always ensure to follow best practices when working with computer hardware.

The Cathode-Ray Tube falls under the category of Soft Copy output. A Cathode-Ray Tube is a device used in older computer monitors and televisions to display images. It uses an electron beam to create a visual display on a phosphorescent screen. This display is not tangible or physical, but rather a digital representation of the image. Therefore, it is considered a form of soft copy output, as it is not a physical printout or hard copy.

Laser printers utilize a laser beam to project an image onto a photosensitive drum, which attracts toner particles to form the desired image. These toner particles are then transferred and fused onto paper to produce the final printout. This process involves electrostatically charged dots, making the laser printer the correct choice.

OLED (Organic Light-Emitting Diode) monitors offer superior image quality compared to other types of monitors due to their ability to emit light directly from individual pixels. This technology allows for high-resolution graphics and videos with vibrant colors, deep blacks, and excellent contrast ratios.

Studio monitors, also known as reference monitors or professional speakers, are specifically designed for accurate audio reproduction in recording studios and sound production environments. They provide a flat frequency response, meaning they reproduce sound faithfully without coloring or altering the audio signal, making them essential for critical listening and accurate mixing/mastering of audio tracks.
