Question 1

In which method of CRT, convergence problem occur
A) beam penetration method
B) shadow mask method
C) both a & b
D) none of these

Accepted Answer

The shadow mask method can have convergence problems due to the need for precise alignment of the electron beams with the corresponding color phosphors.

Question 2

Beam penetration method is used in
A) random scan system
B) raster scan system
C) both a & b
D) none of these

Accepted Answer

The beam penetration method is used in random scan systems to produce color displays. This method relies on the penetration depth of the electron beam into the phosphor layer, which varies with the beam's velocity, to generate different colors.

Question 3

Shadow mask method is used in
A) random scan system
B) raster scan system
C) both a & b
D) none of these

Accepted Answer

The shadow mask method is used in raster scan systems, specifically in CRT monitors, to control the electron beam and create the image on the screen by filtering the electrons through a mask.

Question 4

Graphics data is computed by processor in form of
A) electrical signals
B) analog signals
C) digital signals
D) none of these

Accepted Answer

The answer of Graphics data is computed by processor in...

Question 5

An example of impact device is
A) electrostatic printer
B) inkjet printer
C) line printer
D) laser printer

Accepted Answer

Line printers are an example of impact printers, which work by physically striking a ribbon against the paper to print characters, similar to how typewriters function.

Question 6

To generate the characters , which are required
A) hardware
B) software
C) both a & b
D) none of these

Accepted Answer

To generate characters, both hardware (like keyboards, printers, and other input/output devices) and software (operating systems, drivers, text editors, etc.) are required. Hardware is needed for the physical creation or display of characters, while software is necessary to interpret, process, and manage the characters being used.

Question 7

The method which uses array of dots for generating a character is called
A) stoke method
B) bitmap method
C) star bust method
D) none of these

Accepted Answer

The bitmap method uses an array of dots (pixels) to generate characters on a display screen, where each dot can be turned on or off to create the desired character shape.

Question 8

The hardware devices contain
A) color printer / black white printer
B) plotters
C) both a & b
D) none

Accepted Answer

Both color/black and white printers and plotters are considered hardware devices, as they are physical components used in computing to perform specific tasks, such as printing documents and drawings.

Question 9

An example of black and white laser printer is
A) hp 4000
B) qms
C) both a & b
D) none

Accepted Answer

The answer of An example of black and white laser...

Question 10

An example of color printer is
A) hp 4000
B) qms
C) both a & b
D) none

Accepted Answer

The answer of An example of color printer is
A) hp...

Question 11

Non impact use various techniques to combine three color pigment ______ to produce a range of color patterns
A) cyan , magenta and yellow
B) cyan , white and black
C) cyan , white and yellow
D) black , magenta and yellow

Accepted Answer

Non-impact printers use the combination of cyan, magenta, and yellow (along with black, known as key or K in CMYK) to produce a wide range of colors through a process called subtractive color mixing.

Question 12

Printers produce output by either
A) impact method
B) non impact method
C) both a & b
D) none of these

Accepted Answer

Printers can produce output using either impact methods (like dot matrix printers, which physically strike the paper to print) or non-impact methods (such as inkjet or laser printers, which do not physically strike the paper).

Question 13

What is name of temporary memory where the graphics data is stored to be displayed on screen
A) ram
B) rom
C) frame buffer
D) none

Accepted Answer

The frame buffer is a type of memory specifically used for holding the data that represents the image to be displayed on the screen. It temporarily stores pixel data for the screen display, making it the correct answer.

Question 14

The division of the computer screen into rows and columns that define the no.of pixels to display a picture is called
A) persistence
B) resolution
C) encapsulated post script
D) none

Accepted Answer

Resolution is the division of the computer screen into rows and columns that define the number of pixels to display a picture.

Question 15

LCD are commonly used in
A) calculators
B) portable
C) laptop computers
D) all of these

Accepted Answer

LCDs are commonly used in calculators, portable devices, and laptop computers because they are thin, lightweight, and energy-efficient.

Question 16

LCD is an ______ device
A) emissive
B) non emissive
C) gas discharge
D) none of these

Accepted Answer

LCDs are non-emissive devices because they do not emit light directly. Instead, they use a backlight or reflector to produce images in color or monochrome.

Question 17

Plasma panel is an __ device
A) emissive
B) non emissive
C) expensive
D) none

Accepted Answer

The answer of Plasma panel is an __ device
A) emissive
B)...

Question 18

Plasma device converts
A) electrical energy into light
B) light into electrical energy
C) light into graphical energy
D) none of these

Accepted Answer

The answer of Plasma device converts
A) electrical energy into light
B)...

Question 19

Plasma panel have_________ resolution
A) high
B) good
C) both a & b
D) low

Accepted Answer

Plasma panels are known for having high resolution and good overall picture quality, which makes both options A and B correct.

Question 20

Plasma panel are also called
A) liquid crystal display
B) gas discharge display
C) non emissive display
D) none of these

Accepted Answer

Plasma panels are known as gas discharge displays because they use small cells containing electrically charged ionized gases, or plasmas, to produce images.
