It also sets the platform for increased reliability. Fans of open source programs are adamant about reliable software and highly criticize commercialized versions for being buggy and error-prone. Avid fans even proclaim commercialism is the cause of shoddy software. Another benefit that open source brings to light is the speed at which its products are developed, enhanced, supported and distributed. At the very end of this process, the computer looks for an operating system and if not found, it will prompt the user to tell it where it is. Earlier computers didn't have an operating system and if you have experience with the computers of the early eighties, you'll remember that most to them didn't even have a hard drive! Within Windows, you can set up a home network similar to the way that you set up an Internet connection. Only this time, you'll set up a LAN (Local Area Network) connection. Windows should walk you through setting up a LAN after starting the computer and once complete, you can begin to connect one of your machines to the network. The same goes for disk space, monitor color depth and resolution. In these situations, problems occur the moment that a piece of software attempts to access the things (hardware, memory, space, resolution, etc.) that it cannot find. Because some programs share common files, errors can also occur when these shared files are not up to date. Yes, computers have finally taken over and if you doubt it, we're here to convince you - but not because we want to or because we can. We want to convince you that if you don't take the necessary steps to control that reign, you're going to be left behind further than you could have ever imagined. Computers are everywhere. Take the time to investigate software tools that put you in control and allow you to block access to certain websites. If you use an online service like AOL (America Online), you can use its internal Parental Control settings to block access to various chatrooms and websites. You could even block instant messaging and email from anyone who isn't a fellow AOL user.
