The two most popular software programs used to compress and decompress files are Winzip and StuffIt respectively. There are other programs that do the same thing and there are even programs that can compress and decompress files for both the Windows and the Mac system. However since Winzip and StuffIt are the most popular, we will assume you will use either one to compress and decompress your own files. For just as this new lifestyle was once predicted, we're going to predict that "the old ways" will slowly disappear. We're going to predict that all paper-based transactions (checks, money orders, etc.) and documentation (think of the old filing cabinet system) will disappear. We're going to predict that chips will replace everything that was once transported from one location to another through the trusty post office. In recent news, LiveScience.com reported that "Before the month is even done, April has set a record for virus e-mails."1 In the past, we would be comfortable in telling new computer users not to worry about viruses and that catching a computer virus is rare. Today, that would be some of the worst advice we could give anyone. Since we're describing a home network that will connect to the Internet, you're strongly advised to install a protective firewall program to thwart Internet viruses, worms, or other damaging spyware code. Firewalls prevent - but they don't repair. Only anti-virus and anti-spyware programs can reverse damage. Normally, computer novices aren't interested in controlling the computer. New computer users are typically interested in learning more about how the thing works. However they may be surprised to learn that programming increases computer knowledge as a whole and it can help to diminish the fear associated with using a new computer. Some of the most common parts of a menu bar grants access to File commands, Open commands, Save commands, and Print commands. An example of an error in this part of an interface would be if an option was missing or grayed out (lighter in color). Tool bar - this part of a program displays small icons across the top which represent tools.
