Each of these possesses their own benefits and disadvantages. However, the most popular system among IT professionals is Windows XP Professional.Windows XP is a very good thing to have in the computer world. There are several programs that you can choose to use to manage your personal data and calculate certain mathematical equations. You can open more than one program at a time. Each window contains a different program. (Spring, 2007) A good example of a program is Microsoft Excel. When you get Microsoft XP Home Edition you also get many other programs that come with it, for instance, go to start and then all programs and then go to Microsoft Office. There is Microsoft Office Excel, Microsoft Office Access, Microsoft Office Word, and Microsoft Office Publisher. Each program has its own purpose. Microsoft Excel is spreadsheet software that organizes data in columns and in rows. (McFedries, 2007, 210)The first thing that you will need to obtain is a copy of Windows XP Pro. You can easily obtain this from your local computer store or make use of a copy from a friend. Next, you will need to check to see if your computer system is compatible with MS Windows XP Professional. You will need to make sure that your system has enough random access memory, or RAM, and be sure that your hard drive is large enough to hold the MS Windows XP Professional files with enough room left to save your own files. Another thing to check before going ahead and installing MS Windows XP Professional is the speed of your processor. (Youg, 2001, 510) It should be running at a minimum of 800 MHz. One processor that I prefer is the AMD-K7 processor. Your system will also need to have an installed CD-ROM drive and an available floppy drive. Now you are ready to begin the installation.
