Q101.
Why are back projection setups less heavily used than front projection setups?

a.

They have limited image size

b.

They produce poor image quality

c.

They require a larger projection room

d.

They are more expensive

Discuss
Answer: (c).They require a larger projection room Explanation:Back projection setups are less heavily used than front projection setups because the size of the image is limited by the depth of the projection room behind.
Q102.
What are situated displays?

a.

Large screens for multiple viewers

b.

Small experimental displays

c.

Displays used in lectures and meetings

d.

Displays with high image quality

Discuss
Answer: (a).Large screens for multiple viewers Explanation:Situated displays can refer to both large screens where multiple people can view or interact simultaneously, as well as very small experimental displays.
Q103.
What is the purpose of situated displays?

a.

To offer information

b.

To link spaces

c.

To act as message areas

d.

All of the above

Discuss
Answer: (d).All of the above Explanation:Situated displays serve the purpose of offering information, linking spaces, and acting as message areas.
Q104.
What is an example of a small experimental situated display?

a.

Projected display in a lecture theatre

b.

Gas plasma display in a shop

c.

LCD projector in a meeting room

d.

Situated display mounted by an office door

Discuss
Answer: (d).Situated display mounted by an office door Explanation:An example of a small experimental situated display is one that is mounted by an office door, serving as an electronic sticky note.
Q105.
What is digital paper?

a.

Thin, flexible materials that can be written to electronically

b.

Paper made from recycled electronics

c.

Paper that can display digital images

d.

Paper with embedded computer chips

Discuss
Answer: (a).Thin, flexible materials that can be written to electronically Explanation:Digital paper refers to thin, flexible materials that can be written to electronically and retain their contents even when not connected to an electrical supply.
Q106.
How do tiny spheres on digital paper work to create black or white pixels?

a.

They rotate to make the surface black or white

b.

They emit light to create black or white pixels

c.

They change color when an electronic signal is applied

d.

They reflect light to create black or white pixels

Discuss
Answer: (a).They rotate to make the surface black or white Explanation:In this technique, tiny spheres on digital paper can be rotated electronically to make the surface appear black or white. The spheres stay in their last orientation even after the electronic signal is removed.
Q107.
What is the purpose of the tiny tubes in another technique of digital paper?

a.

To emit light and create pixels

b.

To absorb light and create pixels

c.

To hold reflective spheres for pixel manipulation

d.

To generate electrical signals for pixel control

Discuss
Answer: (c).To hold reflective spheres for pixel manipulation Explanation:In this technique, tiny tubes in digital paper hold light-absorbing liquid and small reflective spheres. The movement of the spheres, either to the top surface or away from it, determines whether the pixel appears white or black. The spheres retain their position once the electronic signal is removed.
Q108.
What is a potential early application for digital paper?

a.

Flexible computer screens

b.

Programmable sheets of paper

c.

Large banners with reprogrammable or animated content

d.

Soft books with changeable pages

Discuss
Answer: (c).Large banners with reprogrammable or animated content Explanation:A potential early application for digital paper is creating large banners that can be reprogrammed or slowly animated. This application benefits from the technology's flexibility and does not require rapid updates or small pixels.
Q109.
What is the long-term goal for digital paper technology?

a.

Creating flexible computer screens

b.

Developing soft printouts that can be changed later

c.

Manufacturing soft books with changeable pages

d.

Designing digital banners with animated content

Discuss
Answer: (b).Developing soft printouts that can be changed later Explanation:The long-term goal for digital paper technology is to have programmable sheets of paper that can be attached to computers to provide "soft" printouts. These printouts can be changed or updated later, offering flexibility and convenience.
Q110.
What is a potential future application of digital paper?

a.

Digital billboards

b.

Electronic sticky notes

c.

Animated magazines

d.

Soft books with changeable content

Discuss
Answer: (d).Soft books with changeable content Explanation:A potential future application of digital paper is the concept of "soft" books. These books would resemble current books with soft pages that can be turned and skimmed, but their contents and covers can be changed when a new book is downloaded from the internet.
