ABSTRACT
Network operating systems is mostly used for the present computer communication networks. Computers use low-level software called an operating system (O/S) to help people build and run their own programs. Operating system software runs not just on laptop computers but also on cell phones, network routers and other so-called embedded Itallow a set of autonomous computers, which are interconnected by a computer network, to be used together in a convenient and cost effective manner. Basically, a network operating system controls other software and computer hardware to run applications, share resources, protects data and establishes communication. Now a days,the most operating systems used are windows and Mac which are provided in market with different versions of advanced technologies.So the report basically briefs about them .
INDRODUCTION
Networking operating system
It is the software that runs on a server and enables the server to manage data, users, groups, security, applications, and other networking functions.[2] The network operating system is designed to allow shared file and printer access among multiple computers in a network, typically a local area network (LAN), a private network or to other networks.
The most popular network operating systems are MicrosoftWindows Server 2003, MicrosoftWindows Server 2008, UNIX, Linux, Mac OS X, and Novell NetWare.
Multiuser File Sharing
A network operating system manages concurrent requests from clients and provides the security necessary in a multiuser environment. A file sharing component is installed in each client machine that interacts with the server to share files and applications as well as devices on the network such as printers, faxes and modems.
Peer-to-Peer
In a Peer-to-peer network operating system users are allowed to share resources and files located on their computers and access shared resources from others.A peer-to-peer network sets all connected computers equal; they all share the same abilities to utilize resources available on the network.
Windows Server 2008 R2:
Microsoft introduced Windows Server 2008 R2 at the 2008 Professional Developers Conference as the server variant of Windows 7. It was launched on October 22, 2009. It is built on Windows NT 6.1, the same core operating system used with the client-oriented Windows 7. It is the first 64-bit-only operating system release from Microsoft. Version enhancements include new functionality for Active Directory, new virtualization and management features, version 7.5 of IIS (the Web server), and support for up to 256 logical processors.
Mac OS X Snow leopard:
Mac OS X Snow Leopard (version 10.6) is the seventh major release of Mac OS X, Apple's desktop and server operating system for Macintosh computers.
Unlike previous versions of Mac OS X, the goals with Snow Leopard were improved performance, greater efficiency and the reduction of its overall memory footprint. Addition of new end-user features was not a primary goal. Much of the software in Mac OS X was extensively rewritten for this release in order to fully take advantage of modern Macintosh hardware. New programming frameworks, such as OpenCL, were created, allowing software developers to use graphics cards in their applications. This is also the first Mac OS release since System 7.1.1 that does not support Macs that use PowerPC processors, as Apple now intends to focus on its current line of Intel-based products.[4] As support for Rosetta was dropped in Mac OS X Lion, Snow Leopard is the last version of Mac OS X that is able to run PowerPC-only applications.
