The Xerox Operating System (XOS) was an operating system for the XDS Sigma series of computers "optimized for direct replacement of IBM DOS/360 installations" and to provide real-time and timesharing support. [1] The system was developed, beginning in 1969, for Xerox by the French firm CII (now Bull). [2]
The Xerox Star workstation, officially named Xerox Star 8010 Information System, is the first commercial personal computer to incorporate technologies that have since become standard in personal computers, including a bitmapped display, a window-based graphical user interface, icons, folders, mouse (two-button), Ethernet networking, file servers, print servers, and email.
Xerox only realized its mistake in the early 1980s, after the Macintosh revolutionized the PC market via its bitmap display and the mouse-centered interface. Both of these were inspired by the Alto. [25] The Xerox Star series was a relative commercial success, but it came too late.
Windows XP and higher were also made available in 64-bit modes. Windows server products branched off with the introduction of Windows Server 2003 (available in 32-bit and 64-bit IA64 or x64), then Windows Server 2008 and then Windows Server 2008 R2. Windows 2000 and XP shared the same basic GUI although XP introduced Visual Styles.
The Xerox 820 Information Processor is an 8-bit desktop computer sold by Xerox in the early 1980s. The computer runs under the CP/M operating system and uses floppy disk drives for mass storage. [ 1 ]
The Xerox 6060 came standard with a single 360 KB 5.25" drive and a 20 MB hard drive. An Iomega Bernoulli 10/10 removable cartridge drive was also offered as a factory option, as well as a "small expansion" sidecar hosting a hard drive for users who found themselves with no internal space left between floppies and expansion cards.
Its functions are to instantly display all open windows as thumbnails for easy navigation to different tasks, display all open windows as thumbnails from the current application, and hide all windows to access the desktop. [49] FileVault is optional encryption of the user's files with the 128-bit Advanced Encryption Standard (AES-128). [50]
Eight-bit computers running CP/M 80 were built around an Intel 8080/8085, Zilog Z80, or compatible CPU. CP/M 86 ran on the Intel 8086 and 8088. Some computers were suitable for CP/M as delivered. Others needed hardware modifications such as a memory expansion or modification, new boot ROMs, or the addition of a floppy disk drive.
