Q231.
How does the von Neumann bottleneck affect computer performance?

a.

It limits the speed of disk access and slows down data retrieval.

b.

It restricts the amount of RAM available for running multiple programs simultaneously.

c.

It increases the capacity of primary memory, leading to faster data processing.

d.

It allows for faster data transfer between RAM and secondary storage devices.

Discuss
Answer: (a).It limits the speed of disk access and slows down data retrieval. Explanation:The von Neumann bottleneck refers to the limitation in data transfer speed between the central processing unit (CPU) and main memory (RAM). This bottleneck affects computer performance by slowing down data retrieval, especially when data needs to be transferred between RAM and secondary storage devices like disks.
Q232.
How does XML differ from SGML in terms of extensibility?

a.

XML is more extensible than SGML because it allows user-defined structures.

b.

SGML is more extensible than XML because it supports Unicode characters.

c.

XML and SGML have the same level of extensibility.

d.

Both XML and SGML have limited extensibility compared to other storage formats.

Discuss
Answer: (a).XML is more extensible than SGML because it allows user-defined structures. Explanation:XML (extensible markup language) is more extensible than SGML (standard generalized markup language) because it allows users to define their own structures and elements within documents. Users can create custom tags and define the structure of the document according to their specific needs, making XML more flexible for various applications.
Q233.
What are the main data types stored by interactive programs?

a.

Images and video

b.

Text and bitmap images

c.

Audio and database records

d.

Binary and executable files

Discuss
Answer: (b).Text and bitmap images Explanation:The main data types stored by interactive programs are typically text and bitmap images. While interactive programs may also handle other data types such as audio, video, and binary files, text and bitmap images are commonly encountered in user interfaces and document-oriented applications.
Q234.
What is the approximate processing speed of computers running interactive programs?

a.

100,000 instructions per second

b.

1 million instructions per second

c.

10 million instructions per second

d.

100 million instructions per second

Discuss
Answer: (d).100 million instructions per second Explanation:Computers running interactive programs process in the order of 100 million instructions per second.
Q235.
What happened when the first program written by one of the authors 'hung'?

a.

All attempts to debug it succeeded.

b.

All attempts to debug it failed.

c.

The program completed successfully.

d.

The program was too slow.

Discuss
Answer: (b).All attempts to debug it failed. Explanation:The first program written by one of the authors 'hung' and all attempts to debug it failed.
Q236.
Which type of fault is occured when the system is behind in responding to the user's cursor movements?

a.

Design fault

b.

Implementation fault

c.

Functional fault

d.

Feedback fault

Discuss
Answer: (b).Implementation fault Explanation:An example of a fault at the implementation stage of the system when the system is behind in responding to the user's cursor movements.
Q237.
What problem arises due to the system buffering user input?

a.

The system crashes.

b.

The interface becomes too fast.

c.

The cursor movements overshoot.

d.

The user's hand-eye coordination is affected.

Discuss
Answer: (c).The cursor movements overshoot. Explanation:One problem arising from the system buffering user input is that cursor movements overshoot, leading to strange effects at the interface.
Q238.
What happens when a user clicks on a menu or icon in a window system while the machine is busy or slow?

a.

The screen becomes a blur of flashing windows and menus.

b.

The system crashes.

c.

The mouse clicks are ignored.

d.

The response becomes faster.

Discuss
Answer: (a).The screen becomes a blur of flashing windows and menus. Explanation:Wen a user clicks on a menu or icon while the machine is busy or slow, all the buffered mouse clicks are interpreted, and the screen becomes a blur of flashing windows and menus.
Q239.
What typically causes problems with delays in window systems?

a.

Swapping programs in and out of main memory.

b.

Slow mouse movement.

c.

Inadequate storage capacity.

d.

Hardware compatibility issues.

Discuss
Answer: (a).Swapping programs in and out of main memory. Explanation:Delays due to swapping programs in and out of main memory typically cause problems in window systems.
Q240.
What is a style of interaction that may be required on a slower machine due to delays in mouse-based interfaces?

a.

Command-based interface

b.

Touch-based interface

c.

Voice-based interface

d.

Gesture-based interface

Discuss
Answer: (a).Command-based interface Explanation:If the delays in mouse-based interfaces cannot be met, a more old-fashioned, command-based interface may be required.
