Privacy advocates say that, for now, it is legal for a prospective employer, during a job interview, to insist that you log into your Facebook page and then click through your “friends only” posts, photos and messages. The ACLU put a stop to companies demanding that applicants turn over their login and password credentials, but “shoulder surfing,” as it’s been dubbed, is legal for the time being. Aleecia M. McDonald, a privacy researcher and resident Fellow at the Stanford Center for Internet and Society, says high unemployment makes it hard to stamp out this practice. “When you have a job market where there are more job seekers than hirers, you’re going to see things like demanding to see your Facebook wall because if you say no, someone else is waiting for that interview.”

There is little doubt that, in a considerably short period of time, the Internet has grown enormously in both its applications and number of users.

Copyright is a legal concept, enacted by most governments, giving the creator of an original work exclusive rights to it, usually for a limited time. Generally, it is "the right to copy", but also gives the copyright holder the right to be credited for the work, to determine who may adapt the work to other forms, who may perform the work, who may financially benefit from it, and other related rights. It is a form of intellectual property (like the patent, the trademark, and the trade secret) applicable to any expressible form of an idea or information that is substantive and discrete.[clarification needed][1]

10 Ways To Stay Safe Online 1. Be a responsible cyber citizen. If you use the Internet, you're a citizen of a global community-a cyber citizen. Just like being a citizen of your local community, being a cyber citizen has responsibilities. Use the Internet to share knowledge that makes people's lives better. Keep safe, use good manners and respect the laws. 2. Use anti-virus software. A computer virus is a program that can invade your computer and damage or destroy information. Anti-virus software is designed to protect you and your computer against known viruses. But with new viruses emerging daily, anti-virus programs need to be updated regularly. Check with the web site of your anti-virus software company to see some sample descriptions of viruses and to get regular updates for your software. Stop viruses in their tracks! 3. Do not open email from unknown sources. Delete email from unknown sources. Watch out for files attached to e-mails, particularly those with an "exe" extension-even if people you know sent them to you. Some files transport and distribute viruses and other programs that can permanently destroy files and damage computers and Web sites. Do not forward e-mail if you are not completely sure that any attached files are safe. 4. Use hard-to-guess passwords and keep them private. Do not write passwords down on small pieces of paper taped to your computer. You would be surprised how many people are sloppy about keeping their passwords private. Passwords that are easy to-guess are a bad choice. In other words, if your name is "Dan" do not make your password "Dan." Change your passwords regularly and don't give your passwords to anyone! Tell your family that combinations of letters, numbers and symbols are harder to crack than just words. 5. Protect computers with firewalls. Install firewalls for your family-it is not difficult. A firewall helps prevent hackers from breaking into your computer or the computers that belong to your family. Firewalls help prevent thieves from stealing and using private information including your phone number and credit card numbers, which may be stored on a family computer. 6. Do not share access to your computers with strangers. Learn about file sharing risks. Your computer operating system may allow other computers on a network, including the Internet, to access the hard-drive of your computer in order to "share files". This ability to share files can be used to infect your computer with a virus or look at the files on your computer if you do not pay close attention. Check your operating system and other program help files to learn how to disable file sharing. Do not share access to your computer with strangers! 7. Disconnect from the Internet when not in use. The Internet is a two-way road. You get information and also send information. Turning off the Internet makes sure that someone else on the Internet can't enter your computer and cause harm. Disconnecting your computer from the Internet when you are not online lessens the chance that someone will be able to access your computer. 8. Back-up your computer regularly. Help your family back up all household computers onto external media such as CD's or diskettes. 9. Regularly download security protection update "patches". Security flaws are regularly found in operating systems and application software. Companies that make software release quick fixes called "patches" that you should install to correct the latest software flaw. It is a good idea to check for security updates on the publisher's Web site for all the software you own. 10. Help your family to check computer security on a regular basis. Evaluate computer security at least twice a year. To help remember, do it when you change the clocks for daylight-savings time! Check for all of the items listed previously.

What is Virtual Reality (VR)? Virtual Reality is generally a Computer Generated (CG) environment that makes the user think that he/she is in the real environment. One may also experience a virtual reality by simply imagining it, like Alice in Wonderland, but we will focus on computer generated virtual realities for this discussion.

Applications of Virtual Reality (VR) Virtual Reality is an ideal training and visualization medium.

One such popular defense tool is a virtual world game called Boarders Ahoy!.

The United States Secret Service is also leveraging the training power of virtual worlds to prepare for national threats.

First-response teams, such as the police and fire departments, are using simulation games to practice dangerous tasks that would otherwise require risky re-enactments.

Social media are media for social interaction, using highly accessible and scalable communication techniques

People gain information, education, news, etc., by electronic media and print media. Social media are distinct from industrial or traditional media, such as newspapers, television, and film. They are relatively inexpensive and accessible to enable anyone (even private individuals) to publish or access information, compared to industrial media, which generally require significant resources to publish information.

World Wide Web enables one to access volumes of information, earn graduate degrees on-line, submit mortgage applications, procure countless goods and services, and communicate instantaneously on a global basis. The increased use of technology in education is accompanied by concerns about technology's role in education.

One study by the Center for Applied Special Technology has shown that students with on-line access scored higher in the areas of information management, communication, and the presentation of ideas. According to one article the use of instructional technology offers great promise in helping "students become independent, critical thinkers, able to find information, organize and evaluate it, and then effectively express their new knowledge and ideas in compelling ways" (CAST, 2000).

In the CAST study the results revealed that students using on-line communication became more confident carrying out and presenting a research project over the course of the study.
