Q201.
What is one advantage of using scanners in desktop publishing?

a.

It allows for electronic cut and paste

b.

It reduces the need for image manipulation software

c.

It eliminates the need for paper documents

d.

It improves the color accuracy of scanned images

Discuss
Answer: (a).It allows for electronic cut and paste Explanation:Scanners in desktop publishing enable electronic cut and paste, allowing for the manipulation and transformation of images without the need for physical glue.
Q202.
What is the purpose of optical character recognition (OCR)?

a.

To enhance the color accuracy of scanned images

b.

To convert bitmap images into text

c.

To store scanned documents in filing cabinets

d.

To preserve the super- and subscripts of scanned documents

Discuss
Answer: (b).To convert bitmap images into text Explanation:Optical character recognition (OCR) is used to convert bitmap images of text into editable text. It allows the computer to "read" the characters on the page.
Q203.
How has OCR software improved over time?

a.

It can now recognize unseen fonts

b.

It operates directly on the optical scan of the document

c.

It is capable of producing output in various formats

d.

It is mainly used for recognizing characters on the page

Discuss
Answer: (a).It can now recognize unseen fonts Explanation:Modern OCR software has advanced to the point where it can recognize and interpret fonts that it hasn't encountered before. It can also produce output in word-processing formats, preserving formatting elements such as super- and subscripts, italics, and centering.
Q204.
What is a challenge when using electronic images in electronic publishing?

a.

The limited number of colors that can be displayed

b.

The variety of formats for storing graphics

c.

The difficulty of capturing images on film

d.

The need for optical character recognition

Discuss
Answer: (b).The variety of formats for storing graphics Explanation:Electronic publishing faces the challenge of dealing with a variety of formats for storing graphics, which can create compatibility issues across different systems and platforms.
Q205.
How does a digital camera capture images differently from traditional cameras?

a.

It records images on film

b.

It uses optical character recognition for image capture

c.

It directly records images into memory using a light-sensitive chip

d.

It requires additional image manipulation software for printing

Discuss
Answer: (c).It directly records images into memory using a light-sensitive chip Explanation:A digital camera captures images directly into memory using a light-sensitive chip, eliminating the need for traditional film. This allows for immediate viewing and electronic manipulation of the captured images.
Q206.
What are the two main types of computer memory commonly referred to as?

a.

Short-term memory (STM) and long-term memory (LTM)

b.

Primary storage and secondary storage

c.

Registers and RAM

d.

Volatile and non-volatile memory

Discuss
Answer: (b).Primary storage and secondary storage Explanation:The two main types of computer memory commonly referred to as primary storage and secondary storage. Primary storage typically refers to RAM (random access memory), while secondary storage includes non-volatile memory such as hard drives, solid-state drives, and other external storage devices.
Q207.
What is the capacity of typical storage in modern personal computers?

a.

Between 7 and 10 items

b.

Between 64 and 256 Mbytes

c.

Around 100 Mbytes per second

d.

10 nanoseconds access time

Discuss
Answer: (b).Between 64 and 256 Mbytes Explanation:The typical storage capacity in modern personal computers is between 64 and 256 Mbytes (million bytes). This refers to the amount of data that can be stored in the RAM of the computer.
Q208.
What is the main difference between volatile and non-volatile RAM?

a.

Volatile RAM retains its contents when the power is turned off, while non-volatile RAM loses its contents.

b.

Volatile RAM is faster than non-volatile RAM.

c.

Volatile RAM is more expensive than non-volatile RAM.

d.

Non-volatile RAM is used in pocket organizers and large computers.

Discuss
Answer: (a).Volatile RAM retains its contents when the power is turned off, while non-volatile RAM loses its contents. Explanation:Volatile RAM, commonly found in computers, loses its contents when the power is turned off. Non-volatile RAM, on the other hand, retains its contents even when the power is turned off, often with the help of a small battery. Non-volatile RAM is typically used for storing setup information or as the main memory in pocket organizers.
Q209.
What is flash memory commonly used for?

a.

Storing photographs in digital cameras

b.

Plugging into a laptop or desktop's USB port

c.

Providing additional RAM in PDAs

d.

Retaining setup information in large computers

Discuss
Answer: (a).Storing photographs in digital cameras Explanation:Flash memory is commonly used for storing photographs in digital cameras. It is a form of silicon memory that retains its content even without power. Flash-based devices can also be used to transfer data by plugging them into a laptop or desktop's USB port.
Q210.
What is the purpose of secondary storage in a computer system?

a.

To provide faster access to frequently used data

b.

To store data permanently even when the power is turned off

c.

To enhance the processing speed of the computer chip

d.

To act as a temporary storage for data being processed

Discuss
Answer: (b).To store data permanently even when the power is turned off Explanation:Secondary storage, such as hard drives and solid-state drives, is used in a computer system to store data permanently, even when the power is turned off. It allows for long-term storage and retrieval of data, unlike primary storage (RAM), which is volatile and loses its contents when the power is turned off.
