In order to fix that problem, the user would have to download an updated version of the shared file (which to say the least - is not an easy thing to find or do). Sometimes, errors occur because a system doesn't have the required drivers or the drivers that are on the system are the incorrect version. The problem is that while upgrading a computer is always an option, technology advances so fast that newer products (such as memory chips, new drives, etc.) aren't always compatible with the machines that we own. This is a common occurrence when newer pieces of hardware require the programming of a newer operating system. If you have a small collection of computers around the house (and a small collection of computer users), you can connect each one of those computers to one another and share data, software, and hardware including a single Internet connection. There are many creative uses for home networking, however it's an ideal situation when upgrading each computer to the same capability is financially out of the question. Another benefit that open source brings to light is the speed at which its products are developed, enhanced, supported and distributed. This is because the people who regularly contribute to an open source product do so for unmotivated reasons (other than perhaps to feed the ego.) They're highly talented, they're available, and they care. sit file, you can select a single file or a group of files from within Explorer, and right-click the selection. Again, depending on how you installed Winzip or StuffIt, you can click the "Add to Zip" or "Add to Sit" option and have these programs automatically archive the file(s) into one. The above illustrations were just a couple of examples of how far computer technology has grown, and how far we've pushed "user-friendliness" to its limit. Eventually, the keyboard and mouse will have to play a role when computer newbies have to work with one as a cash register, as a hotel booking program, or as a library's catalog system.
