Some popular desktop operating systems include Apple OS X, Linux and its variants, and Microsoft Windows. Operating Systems: It is the interface between the user and the computer hardware. Historically operating systems with networking capabilities were described as network operating system, because they allowed personal computers (PCs) to participate in computer networks and shared file and printer access within a local area network (LAN). A distributed operating system is an ordinary centralized operating system but runs on multiple independent CPUs. These include support for processors and the various protocols that allow computers to share data. It then adds functions that allow access to shared resources by a number of users concurrently. Operating systems can be found on many devices that contain a computer: from cell phones, to video game consoles, to computers and network servers. Thesystems support the users accessing the network as wellas process requests for specific documents and usage ofhardware. This is because only one user at a time uses a desktop computer; however, multiple users simultaneously use server computers. Theme of my lecture today • Technology based on the Internet ... – Truly network aware operating system • For network management • Distribute computing and management – Character base user interface – All we care is a running code! Solaris™, a version of UNIX developed by Sun Microsystems, is a network operating system designed for e-commerce applications. Many network operating systems can detect hardware within the system to allow for asset discovery within the network. These include support for processors and the various protocols that allow computers to share data. The first characteristic of network operating systems is the support component: Network operating systems provide support for the multiple processors, applications, and hardware devices that make up a network. Network Operating System is an operating system that includes special functions for connecting computers and devices into a local-area network (LAN) or Inter-network. The main difference between network operating system and distributed operating system is that a network operating system provides network related functionalities while a distributed operating system connects multiple independent computers via a network to perform tasks similar to a single computer.. An operating system works as the interface between the user and the hardware. Some popular desktop operating systems include Apple OS X, Linux and its variants, and Microsoft Windows. It is considered as the primary form of an operating system for the distributed architecture. The server is the center of the system, allowing access to resources and instituting security. What features of a network operating system does your organization find most valuable? Network Operating System runs on a server. Overview of NOS Characteristics Network operating systems (NOSs) distribute their functions over a number of networked computers. The third characteristic of network operating systems is the user setup component.Network operating systems create user accounts and manage the users logging into and out of thenetwork. Some popular network operating systems are Novell Netware, Windows NT/2000, Linux, Sun Solaris, UNIX, and IBM OS/2. Every computing device needs an operating system, or OS, to function, and so does a computer network. Deal with users logging on. A network operating system is made up of software and associated protocols that allow a set of computer network to be used together. Network OS. Examples of a network operating system include Windows Vista, Windows 8 and Mac OS X and of course all the mainframe operating systems. Artisoft’s LANtastic- This is a simple, user-friendly NOS that supports most PC operating systems. Current FreeBSD Network operating systems support the basic underlying operating features of networks. Characteristics of Networking Operating Systemsmanages software and hardware installations to keep users from installing unauthorized softwareand devices. Earlier versions of Microsoft Windows and Apple operating systems were not designed for single computer usage and not network usage.
