OPERATING SYSTEM3

Definition of OPERATING SYSTEM Types Features Examples Recent Development4

OPERATING SYSTEM aninterfacebetweenhardwareanduser management and coordination sharing the resources of a computer acts as a host forcomputing applicationsrun on the machine handle the resource allocation and access protection of the hardware offer a number of services to application programs and users Applications access these services throughapplication programming interfaces(APIs)

TYPES Real Time OS Single user single tasking Single user multi-tasking Multi user multi tasking6

FEATURES Program execution Fast access Protected & supervisor mode Memory management Virtual memory Multi tasking Disc access & file systems Networking Security File System support in modern operating systems Journalized file systems Device Management Drive Management Data Management Access Control Link between soft & hardware Fixing errors Optimization Use of utilities

7 supporting a variety of networking protocols, hardware, and applications computers running dissimilar operating systems can participate in a commonnetwork computing, files, printers, and scanners using either wired or wireless connections. Networks can essentially allow a computer's operating system to access the resources of a remote computer

MICROSOFT WINDOWScurrently supports NTFS andFATfile systems (includingFAT16andFAT32) network file systemsshared from other computersthe ISO 9660 and UDF file systems used forCDs,DVDs, and other optical discs such asBlu-ray each file system is usually limited in application to certain media, for example CDs must use ISO 9660 or UDF, and as ofWindows Vista10

OTHER OSs Older operating systems which are still used Mac OS, the non-Unix precursor to Apple's Mac OS X;BeOS;XTS-300 most notablyAmigaOS 4andRISC OS, continue to be developed as minority platforms operating systems for 8 bit computers - Apple's DOS (Disk Operating System) 3.2 & 3.3 for Apple II, ProDOS, UCSD, CP/M available for various 8 & 16 bit environment GNU Hurdis designed to be backwards compatible with Unix, Singularityis a project atMicrosoft Researchto develop an operating system with bettermemory protectionbased on the .NET managed code model.

the latest public release version ofMicrosoft Windows, a series ofoperating systemsproduced byMicrosoft.

Windows 7 was intended to be a more focused, incremental upgrade to the Windows line, with the goal of being fully compatible with applications and hardware with which Windows Vista is already compatible.

focused onmulti-touchsupport, a redesignedWindows Shell with a newtaskbar, referred to as the Superbar,RECENT DEVELOPMENTWINDOWS 7 a home networking system called Home Group, and performance improvements.

Some applications that have been included with prior releases of Microsoft Windows, includingWindows Calendar,Windows Mail, Windows Movie Maker, andWindows Photo Gallery, are not included in Windows 712References
