Chapter 8

Computers hold valuable information important to the user. “Computer security risks are any event or action that can cause a loss of or damage to computer equipment, software, data, and information, or processing capability in the computer.” A virus is “designed to destroy or corrupt data” by altering the way they work. Viruses are common so it’s necessary that precautions be made against them. One such precaution is antivirus programs which are designed to “detect, disinfect, and protect computers and networks from viruses.” The most common way for a virus to be spread is by inserting an infected storage media or by infecting an infected file, many things found on the Internet are infected, sometimes from e-mail. If you download or purchase anti-virus software it can keep your computer safe and alert you of any problems. These programs are “designed to detect, disinfect, and protect computers and networks from viruses.” Most anti-virus programs can also repair the infected files.

It is possible to find almost anything on the Internet including damaging material. It is important to be able to limit the amount of objectionable material children can view on the Internet. Since their may not always be an adult present “Filtering software programs prevent browsers from displaying materials from targeted sited or materials that contain certain keywords or phrases.” In an educational facility where having computers present is more needed and expected there also needs to be the use of filtering programs so children stick to the educational use of computers. I know first hand from volunteering with certain programs that kids will abuse computers if left unattended or unfiltered. It's hard to devote your time to a child who needs help if you are worried that the kids on the computer are looking at harmful material. I'm glad there are programs able to filter out unacceptable material and block what the educator chooses to ban.

Since last week I have learned more about power point and the creative things you can do with it. I would definitely choose this as a method to help teach a lecture to my class. I love to have visual aids in order to keep attention and to help outline notes for my students. It shows what I think is most important in the lecture and what the focus will be. I'm looking forward to seeing the other power point presentations.
