They don't require any extensive programming background and they don't need to be encrypted with some weird, expensive compiler. Batch files are plain text files, and you can build one for your own personal use with Windows' Notepad. You could make a batch file that loads up your favorite websites at once for example, or you could make a batch file that fills your desktop with the most important applications for the day. 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. You already have such a program on your computer and it's Windows' Add/Remove Programs (available from the Control Panel). This software will assist you with deleting programs that you not only no longer want, but additional files that these program use as well (dynamic link libraries, database files, registry references, shortcut icons, etc. File viruses may also be referred to as parasitic viruses, however should a virus work from both the boot-sector and from an infected program, the virus is then known as a multipartite virus. Why viruses exist remains a mystery, however we had privy access to the mind behind a virus programmer who explained his motivation behind his destructive inclinations. While it doesn't offer as many editing tools, it does provide the essentials and it can open/save graphics in .bmp, .gif, and.jpg format (the latter two being the most commonly format used for Internet eye candy). Media Player. Real Player and QuickTime are the first programs we think of when we think about multimedia. To enable Internet access for each computer, this router will need to connect with a modem of the host machine. Once the hardware is set up correctly (you'll need to read the instruction manual of your equipment for details), you can then setup the network from Windows on each machine. Within Windows, you can set up a home network similar to the way that you set up an Internet connection.
