Worst case scenario: the motor can overheat and stop working as well. No motor equals no computer. Keep your computer's fan clean by preventing the fan from getting dirty or dusty in the first place. Use the computer in a dust-free environment and never smoke around it. Nicotine and tar mean certain death when it comes to computer fans, however should you find a need to clean the fan, do so with extreme care. For the life of us, we can't figure out why anyone other than a rocket scientist would want to install a different version than this free one that comes pre-installed. Windows calculator has two interfaces: an easy one, and a scientific one. So perhaps a rocket scientist could fare well with Windows Calculator after all! But sometimes Windows' Add/Remove Programs isn't enough. Although this software does a pretty good job of removing unwanted programs, it can leave some files behind even after a complete uninstall - files which become orphan files. And it's these orphan files that can really clutter up a hard drive and shorten the life of an otherwise, young and robust PC. Programming a computer is creating a sequence of instructions that enable the computer to do something.1 The people who program computers (called programmers) use a programming language to communicate with a computer. You might have heard of some of these languages in the past such as Visual Basic, C++, or Fortran. This article will describe this recent phenomenon and describe some of its benefits for the software using community. In a nutshell, open source software is software made by everyone - for everyone. The hopes behind its development is that through its open access, it will evolve into something that represents the true desires of computer users. You'll want to first, select the computers that will connect to each other and then install the network cards inside each of them. Then you'll connect a cable to each computer that will communicate with the server. These cables won't connect to the server directly. Instead, they'll connect to the router.
