    2. Files on the disk are stored in the first available spaces, and broken up as necessary to do that. If there are more than about 10% of the files split up into pieces, then the disk is called "fragmented."

    3. It takes longer for the system to find and join all the pieces of fragmented files than to retrieve files that are all together (contiguous).

    7. The /f switch caused ChkDsk to fix the problems that it encounters, if possible.

    9. New viruses are always being produced, and the anti-virus program's data files need to be kept up-to-date in order to protect your computer against these new ones.

    11. Run an anti-virus program on all computers in the network.

    12. Spyware may be part of a legitimate program or the entire program. Its purpose is to send back information about your computer and how you use it to someone, who can use that information to send you spam or redirect your browser while you are using it.

    13. Cookies are small files that allow a website to know if you frequently access it. Some cookies are called "tracking" cookies, and help the website keep track of other websites that you visit. All cookies can be safely deleted after an Internet session.
