Windows 2000 was designed from Windows NT for better security. Unfortunately that means the driver model has changed, so all hardware needs drivers that are compatible with 2000 to use it. Windows XP was build from 2000, knocking out the 9x series in use for home computer
Windows 98 is based on Windows 95 and uses the FAT32 file system. Windows 2000 is based on Windows NT and uses the NTFS file system. Windows 2000 is *a little* more secure.
2000 was designed for the enterprise (corporate office) so it can easily be networked and connect to a domain (servers.

98 was designed for the home user but networking is still possible.

2000 is newer than 98 (obviously)

XP Home is the next version for the home user

XP Pro is the next version for the corporate environment (offices).
