Question 1

COGNITIVE ASSESSMENT Which of the following terms is used to describe a program that hides in a computer and allows someone from a remote location to take full control of the computer?
A) a virus
B) a worm
C) a Trojan horse
D) a rootkit

Accepted Answer

A rootkit is a program that is designed to hide its own existence and any activity it may engage in on a computer system. Rootkits often allow someone from a remote location to take full control of the computer without the knowledge of the user. Viruses, worms, and Trojan horses are all types of malware that can cause damage to computer systems, but they do not necessarily allow someone to take full control of a computer from a remote location.

Question 2

COGNITIVE ASSESSMENT You have received an email that is directing you to a phony website that looks like the website for your mortgage company.What kind of message is this?
A) pharming
B) pop-up
C) spam
D) phishing

Accepted Answer

This is a classic phishing attempt, where scammers create fake websites that look like legitimate ones in order to trick people into entering their personal information. In this case, the email is directing the recipient to a phony website that mimics their mortgage company's website, likely in an attempt to steal their login credentials or other sensitive information. It's important to always double-check the URL of any website you visit to ensure it's legitimate, and never enter personal information on a site you don't trust.

Question 3

COGNITIVE ASSESSMENT What was the original purpose of a screen saver?
A) to prevent images from being permanently etched on a monitor's screen
B) to protect a computer by requiring a password to deactivate it
C) to prevent access by hackers and avoid viruses
D) to save energy by reducing the monitor activity

Accepted Answer

The original purpose of a screen saver was to prevent images from being permanently etched on a monitor's screen. This was a common problem in the early days of computer monitors, which used CRT technology. When a static image was displayed on the screen for too long, it could become "burned in" and leave a ghostly image, even when the screen was turned off. Screen savers were designed to prevent this by displaying moving images or patterns when the computer was inactive, thereby reducing the likelihood of image persistence.

Question 14

COGNITIVE ASSESSMENT What is the real-time exchange of messages, files, audio, and/or video with another online user called?
A) text messaging
B) chat
C) mobile inter-communication exchange
D) instant messaging

Accepted Answer

The real-time exchange of messages, files, audio, and/or video with another online user is commonly known as instant messaging. While text messaging and chat can also involve real-time communication, they may not necessarily allow for the exchange of files, audio, or video. "Mobile inter-communication exchange" is not a commonly used term and is not a recognized term for this type of communication.

Question 15

COGNITIVE ASSESSMENT Why is a fragmented disk slower than one that is defragmented?
A) A fragmented disk contains temporary Internet files and unused program files that need to be deleted.
B) A fragmented disk contains programs that were deleted using Windows Explorer.
C) A fragmented disk has many files stored in noncontiguous sectors.
D) A fragmented disk has no index.

Accepted Answer

A fragmented disk has many files stored in noncontiguous sectors, which means that the read/write head of the disk needs to move more to access data. This slows down the disk performance as compared to a defragmented disk where all the files are stored in contiguous sectors, reducing the seek time for accessing data. Options A and B are misleading as they do not directly explain the impact of fragmentation on disk performance. Option D is incorrect since a fragmented disk does have an index, but it may not be optimized for performance.

Question 16

COGNITIVE ASSESSMENT Which of the following features is offered by WBT?
A) DTP with online follow-up

Question 17

COGNITIVE ASSESSMENT Which of the following are valid steps toward virus protection?
A) purchase a reputable antivirus program, update antivirus definitions regularly
B) delete a personal firewall, scan your computer for malware
C) open e-mail attachments and then scan them for viruses, install operating system updates
D) stay informed about viruses, never visit web sites unless they are approved by the Virus Protection Agency (VPA)

Accepted Answer

The best choice is A because it recommends purchasing a reputable antivirus program and regularly updating antivirus definitions, which are effective steps toward virus protection. B is incorrect because deleting a personal firewall can actually weaken virus protection, and scanning for malware is not enough to fully protect against viruses. C is incorrect because opening email attachments before scanning them for viruses can lead to infecting the computer, and installing operating system updates alone is not enough to fully protect against viruses. D is incorrect because staying informed about viruses is important, but relying on an agency to approve websites is not a guarantee of virus protection.

Question 18

COGNITIVE ASSESSMENT Which of the following terms is used to describe a program that copies itself repeatedly, using up resources and possibly shutting down the computer or network?
A) a virus
B) a worm
C) a Trojan horse
D) a rootkit

Accepted Answer

A worm is a type of malicious software that spreads copies of itself to other computers within a network or through the internet, using up resources and potentially causing damage. It does not require a host program to run, unlike a virus or Trojan horse. Rootkits are another type of malicious software that are designed to hide their presence on a system, while a Trojan horse refers to a type of malware that appears harmless but actually carries out malicious actions.

Question 19

COGNITIVE ASSESSMENT What does a disk cleanup utility do?
A) organizes files into consecutive sectors
B) creates an index of files on the disk
