The most popular places to find shareware is within thousands of download libraries, however the companies (and even independent programmers behind shareware) are increasingly offering shareware from their own websites. A simple Google or Yahoo search for a particular type of program will yield all sorts of results that point you toward items that you can try before you buy. One very important choice you'll want to keep your eye on is the option to return to the main menu. This way, you can return to the beginning of a system and start over in case you get lost among the way. Another important choice that you want to keep your eye on is the choice to get help! This option may not be available on every device that you encounter, but when it is available, be sure to use it. As a software user, this means you can contribute to an open source project as well, and help to develop it into a product that reflects your direct preferences. 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! Problems in this part of an interface are uncommon, however if you find yourself repeatedly clicking an icon with no results, you can correctly describe the problem by referring to the toolbar. Minimize, Restore, and Exit buttons - these three buttons are usually located on the right-most upper part of a program's interface and each allow you to minimize a program's screen, restore it to its original size, or shut down the program completely. The easiest and cheapest method uses an Ethernet connection, which requires a series of network cards, a cable for each computer, and a router. The network card is similar to the old modems we used in the past to connect to the Internet, however in a home network, it's used to communicate with every computer that's connected to it. Apparently, the Windows XP operating system requires components that weren't developed at the time Windows 98 was distributed and if we were to install Windows XP on this machine anyway, the new operating system would look for hardware that the computer didn't have. And that would be an instant recipe for failure.
