What is the difference between Windows 98 Windows 2000 and XP?
Windows 98 was the polished, final, improved version of Windows 95.
It was easier to use, suffered a lot fewer crashes , freezes and other forms of torture familiar to Windows users than the 95 version did and had a higher support for USB.
Windows 95 and 98 are somewhat the same disregarding graphics. 95 was the big bang for Microsoft. After such a success and with the Internet on the rise, 98 came out configured for a more optimal net configuration. But not that stable or reliable. Windows 2000 and Windows NT are pretty much the same thing just different release dates. NT based OS's are a lot more stable considering they run on NTFS(hince NT) whereas 98/95 run on FAT32 which is of course less stable. And well XP just plain over did it, XP just looks pretty. XP is way to big, takes way too much start up and RAM dedication. Make sure you have a solid Gig of RAM before going XP, and upgrading to Service Pack 3 is advised.
Windows 95 and 98 (and Windows 98SE and Windows Me) were designed and marketed to Home users. Windows 2000 is an expansion of Windows NT and both were marketed for Businesses. Windows XP is a hybrid of the two allowing for the selection of either file system at the time of installation and is much more stable. It's Microsoft attempt to wean users onto two flavors of the same OS, thus keeping their costs down and better compete with Unix.
If you're running Windows XP Home Edition, you can run rather successfully with 250mb of RAM (even 128mb if all you're doing is Word and email, although I don't recommend it). If you're running Windows XP Pro, then I would recommend that you run with 500mb of RAM, with 1gb only being necessary for high-end gamers, or graphic users such as CAD-CAM or movie.
It also depends upon if you're a work station or a stand-alone system. Tens of thousands of work stations run just fine using Windows XP Pro with just 250mb of RAM, whereas stand-alone systems need more.
Windows 98 is based on DOS which is an old operating system created years ago hence why it crashes a lot.
Windows XP (and Vista, 200, and NT) are completely rewritten from scratch. They are much more reliable and have replaced Windows 98.
First of all Windows 98 cannot work with most hardware. Windows XP can work with hardware that 98 can work with and more. Windows XP haves better themes than 98. XP can work with more software than 98, XP can also work with software that 95, 98, Me, and 2000 works with. XP haves better icons. 98 is slow. XP is fast. XP comes with more security features than 98.
