Working offline is a convenient timesaving trick for those who want to perform some tasks without an Internet connection.

Each time you open your e-mail program (such as Outlook Express) or visit a Web site, the information you access can be stored on your computer and saved for future use. This allows you to retrieve e-mails or Web sites you have previously downloaded or visited and perform some tasks offline.

In the twenty-first century the phrase "never talk to strangers" is good advice even for adults. Although many may feel safe behind their computer screens, mother is still right -- strangers cannot always be trusted, even on the Internet. Recent news about the "Craigslist Killer" -- a medical student who was accused of using Craigslist to rob users upon meeting and ultimately killing one -- has left many Missourians skeptical of how safe it is to buy and sell items online.

Traveling Internet users tap into any public wireless hotspot at local restaurants, coffee shops and libraries to check e-mail and visit Web sites on the road. An April 2009 study by Pew Research Center showed that 56 percent of adult Americans have accessed the Internet through a wireless network. Unfortunately, cyber criminals are taking advantage of these conveniences, causing headaches for Wi-Fi users across the country.
