Why is buffering often necessary when the computer is accessing a slower device like a printer?
-
Because buffering makes the printer work faster
-
Because buffering frees the CPU to do other things while printing or accessing other i/o devices
-
Because buffering wastes less ink
-
Because buffering allows the printer to print in colour
Correct Answer
A. Because buffering frees the CPU to do other things while printing or accessing other i/o devicesExplanation
Buffering is often necessary when the computer is accessing a slower device like a printer because it allows the computer's CPU to perform other tasks while waiting for the slower device to complete its operations. By temporarily storing data in a buffer, the CPU can continue executing other instructions instead of being idle and waiting for the printer to finish. This improves overall system efficiency and allows for multitasking, as the CPU can handle multiple operations simultaneously.Rate this question:

Pen Plotters are ideal for
-
Producing bills
-
Producing maps
-
Producing photo posters
-
Producing pay slips
Correct Answer
A. Producing mapsExplanation
Pen plotters are ideal for producing maps because they are capable of creating precise and detailed drawings. Maps require accurate representation of geographical features and pen plotters can achieve this by using pens of various colors and thicknesses. The plotters can also handle large paper sizes, allowing for the creation of maps with extensive coverage. Additionally, pen plotters can produce high-quality prints with smooth lines and consistent shading, making them suitable for producing maps that are visually appealing and easy to interpret.Rate this question:

Which of the following printers is/are suitable for printing photos?
-
Dot matrix printer
-
Dot matrix printer, laser printer
-
Inkjet printer, laser printer
-
Dot matrix printer, inkjet printer, laser printer
Correct Answer
A. Inkjet printer, laser printerExplanation
The inkjet printer and laser printer are suitable for printing photos because they both have the capability to produce high-quality images with vibrant colors and sharp details. Inkjet printers use liquid ink that is sprayed onto the paper, resulting in smooth color transitions and accurate color reproduction. Laser printers, on the other hand, use toner and heat to fuse the image onto the paper, providing crisp and precise prints. Both printers offer the necessary resolution and color accuracy required for printing photos.Rate this question:

The difference between a raster and a vector device is that
-
A raster device is more expensive than a vector device and a raster device produces complete lines.
-
A raster device is an input device while a vector device is an output device
-
A raster device treats the output as a whole whilst a vector device treats the global output as being made up out of a number of different parts. So vector devices produce complete lines whilst raster devices produce images as a series of dots.
-
Raster devices are output devices while vector devices are input devices.
Correct Answer
A. A raster device treats the output as a whole whilst a vector device treats the global output as being made up out of a number of different parts. So vector devices produce complete lines whilst raster devices produce images as a series of dots.Explanation
The correct answer states that a raster device treats the output as a whole, while a vector device treats the global output as being made up of different parts. This means that vector devices create complete lines, while raster devices produce images as a series of dots. This explanation highlights the fundamental difference between raster and vector devices in terms of how they handle and represent output.Rate this question:

Which of the following are all output devices?
-
Dot matrix printer, MICR, CRT monitor
-
CRT monitor, laser printer, Pen plotter
-
LCD monitor, laser printer, OMR
-
Pen plotter, LCD monitor, barcode reader
Correct Answer
A. CRT monitor, laser printer, Pen plotterExplanation
The correct answer is CRT monitor, laser printer, and Pen plotter. These devices are all output devices because they are used to display or produce information from a computer system. A CRT monitor is a display device that shows visual output, a laser printer produces printed output, and a Pen plotter is a device that uses pens to draw graphics or designs on paper.Rate this question:

Which of the following devices produce a softcopy?
-
CRT monitors, LCD monitors
-
CRT monitors only
-
All monitors and all printers
-
LCD monitors only
Correct Answer
A. CRT monitors, LCD monitorsExplanation
CRT monitors and LCD monitors both produce a softcopy. A softcopy refers to the electronic version of a document or image that is displayed on a screen. CRT monitors use cathode ray tubes to display images, while LCD monitors use liquid crystal displays. Both types of monitors can display digital content and do not require physical printing, making them softcopy devices.Rate this question:

Which of the following is/are impact printers?
-
The the dot matrix printer
-
The the dot matrix printer, the inkjet printer
-
The laser printer
-
The dot matrix printer, the laser printer, the inkjet printer
Correct Answer
A. The the dot matrix printerExplanation
The dot matrix printer is an impact printer because it uses a print head that strikes against an ink ribbon to create characters on the paper. The impact of the print head against the ribbon transfers ink onto the paper, creating the printed text or images. This is in contrast to non-impact printers like inkjet printers and laser printers, which use different methods such as spraying ink or using lasers to create prints.Rate this question:

How does a hardcopy differ from a softcopy?
-
A hardcopy is output whilst a softcopy is what we input.
-
A hardcopy is what we input whilst a softcopy is output.
-
A hardcopy is output which lasts for a short time only whilst a softcopy is permanent.
-
A hardcopy is permanent and tangible whilst a softcopy is not tangible and can be easily changed.
Correct Answer
A. A hardcopy is permanent and tangible whilst a softcopy is not tangible and can be easily changed.Explanation
A hardcopy refers to a physical printout or document that can be held and touched, making it permanent and tangible. On the other hand, a softcopy is a digital or electronic version of a document that is not tangible and can be easily modified or edited.Rate this question:

A flat panel display monitor like an LCD
-
Is less expensive than a CRT monitor.
-
Produces a better output than a CRT monitor but harms the eyes more.
-
Is less expensive than a CRT monitor but is less harmful to the eyes
-
Has a lower power consumption than CRT monitors.
Correct Answer
A. Has a lower power consumption than CRT monitors.Explanation
An LCD monitor has a lower power consumption than CRT monitors. This means that it requires less electricity to operate, resulting in lower energy costs and a smaller environmental impact. LCD monitors use a backlight to illuminate the screen, while CRT monitors use electron beams to create images. The use of a backlight in LCD monitors is more energy-efficient compared to the power-hungry electron beams used in CRT monitors. Therefore, choosing an LCD monitor over a CRT monitor can help save energy and reduce electricity consumption.Rate this question:
