A network operating system (NOS) controls software and hardware on a network, allowing computers to communicate and share resources. Key characteristics of a NOS include supporting multiple processors and devices, managing security through user authentication and authorization, setting up user accounts and access permissions, providing print and file services, and managing email services. Common NOS software includes Microsoft Windows Server, Mac OS X, and UNIX/Linux.

- 3. What is a NOS? A Network Operating System (NOS) is a software program that controls other software and hardware running on a network. It also allows multiple computers, known as network computers, to communicate with one central hub and each other to share resources, run applications, and send messages. Such a system can consist of a wireless network, Local Area Network (LAN), or even two or three computer networks connected together. Administrators running these networks typically have training in different network operating systems. 3

- 5. SUPPORT 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. The systems support the users accessing the network as well as process requests for specific documents and usage of hardware. NOSs also provide protocol requests from users, including Transmission Control Protocol/Internet Protocol (TCP/IP) and other protocols. 5
- 6. Controls Support The second characteristic of network operating systems is the security component. NOSs manage the authorization and authentication of users, computer workstations, and other devices accessing a network. If an intruder tries to access a network, the NOS blocks the unauthorized user/computer and logs the intrusion attempt within its log files. The NOS also manages software and hardware installations to keep users from installing unauthorized software and devices. 6
- 7. Setup 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 the network. The systems also manage what file and directory services a specific user has access to, users accessing the network remotely, and how the network's graphical interface looks to specific users. 7
- 8. Printing and File Services The fourth characteristic of network operating systems is the printing and file services component. Like other operating systems, network operating systems manage all printing, storage, backup, and duplication services for computers and users accessing a network. The systems also control access to the Internet, local-area (LAN) and wide-area networks (WAN), port routing, and internal web services known as Intranet. An NOS filters documents and files through the printing/file services immediately. More than one user can send documents and files through the network for printing, backing up, or other types of processing. 8
- 9. EMAIL SERVICES The Fifth and final characteristic of network operating systems is the email component. An NOS manages electronic mail, also known as email, for the entire network, including users accessing the NOS remotely and from the Internet. The NOS blocks SPAM and other problematic emails and sends/receives email, as well as lets users create additional email accounts. 9
