Windows 98 is a great illustration of the flexibleness an operating system provides. Windows 98 runs on hardware from thousands of vendors. It can accommodate thousands of assorted printers, disk drives and special peripherals in both possible combination....If you motivation to get a intact essay, distinguish it on our website: Orderessay
