Explanation:
The screensaver software can also be used as a basic security measure.
A screensaver is a program initially designed to prevent phosphor burn-in on CRT and plasma
computer monitors by blanking the screen or filling it with moving images or patterns when the
computer is not in use. Modern screensavers are used primarily for entertainment or security.
Answer option D is incorrect. A cookie is a small bit of text that accompanies requests and pages as
they move between Web servers and browsers. It contains information that is read by a Web
application, whenever a user visits a site. Cookies are stored in the memory or hard disk of client
computers. A Web site stores information, such as user preferences and settings in a cookie. This
information helps in providing customized services to users. There is absolutely no way a Web server
can access any private information about a user or his computer through cookies, unless a user
provides the information. A Web server cannot access cookies created by other Web servers.
Answer option B is incorrect. Visual Time Analyzer is software, which is used to track computer
activities, working time, pauses, projects, costs, software, and Internet use automatically. It shows
detailed, illustrated reports of the activities. Visual Time Analyzer also tells which programs were
used for how long, when, and by whom. It gives parents control over their children’s use of the
computer. Visual Time Analyzer software has privacy safeguards. It does not monitor all user data
such as passwords and personal documents, and does not record specific keystrokes or run screen
captures as a background process.
Answer option A is incorrect. Adware is software that automatically downloads and display
advertisements in the Web browser without user permission. When a user visits a site or downloads
software, sometimes hidden adware software is also downloaded to display advertisement
automatically. This can be quite irritating to user. Some adware can also be spyware.
