You can monitor the conversations your children have with their friends and teach them appropriate online behavior at the same time. You can make recommendations and create a private time for quality time as well. The third step involves blocking access to inappropriate areas altogether. You and your children may not always agree about what's appropriate, but as a guardian, you're in control and you're ultimately responsible for their safety. You may find yourself in need of more hard drive space for all those videos and mp3s that you download, for example. Or maybe that cool new programming language you've been dying to try requires more memory than what your computer currently has. Unless the activities on your computer are restricted to pure textual output (plain text files), your computer is going to get filled with a lot of "stuff" - stuff that can overfill a PC's capacity too much for the computer to function well. But Windows Media Player, also free and pre-installed, does a fine job at transmitting Internet-bound sound and video. With this application, you can easily listen to .wav files, .midi files, and even tune into a little Internet radio if you like. System Tools. Although there are too many to list here, Windows provides more than a handful of useful utilities that will monitor system resources, organize files, repair damaged disks, and more. As an example, to load up Microsoft's simple editing program, you had to type the name of the drive that the program was on, the directory that the program was in, and then the name of the program. So if Microsoft Edit was in a directory or folder named "Process," you could start the program by typing, "C:>process\edit. These old computers booted an MS-DOS type operating system from drivers stored onto a floppy disk, and in order to use a program, users would remove the boot floppy and then insert a new floppy that contained the program. The floppy not only stored the program (word processor, spreadsheet, etc.), it also stored the drivers that the program needed to communicate with the computer's hardware. In fact, if you can remember that most systems are designed along the line of menus and the selections of a few options on these menus, you'll do just fine no matter how many buttons there are to push. For example, when you're faced with an electronic system, look for a main menu. Most main menus display themselves as soon as a device is turned on, so chances are that if you're standing before a device that shows a bunch of choices to do something, you're looking at a main menu.
