Instead of speaking to a human being, chances are that you spoke to a computer that not only responded to what you said and followed the commands that you gave it, it also asked you for more information such as your full name or credit card number. In this case, a person (such as yourself) operated a computer without even knowing it! You aren't "stuck" using open source software the way you would be stuck using an expensive word processor or database. You have the same access to open source software as its programmers have and in essence, you are your own customer! Perhaps at this point you're wondering where you can get in on this wonderful opportunity. Schools can research student versions of commercial software or ask for a school discount. Just because school rates aren't advertised, it doesn't mean that they aren't available. Freeware or open source software (also described in another one of our articles) is another alternative to pirating commercial-ware, as well as shareware. So you should install a firewall on the computer that grants access to the computer, and then install an anti-virus and anti-spyware program on each of the remaining computers in the network. If you have files that shouldn't be shared (bank statements, credit card information, etc.), you can restrict their access in one of several ways. Smartphones - The Computer In Your Pocket If you haven't heard of smartphones, we'd like to learn where you've been hiding all this time. Smartphones have been all over the news and chances are, you do know what they are - only you know them under a different name. Smartphones are mobile phones with computer like capabilities. However since Winzip and StuffIt are the most popular, we will assume you will use either one to compress and decompress your own files. If you download a compressed file from a website or file library that ends in an .exe extension, take note that although the file is compressed, it's typically a file that will install a program onto a computer.
