Firewalls act as a barrier between the network and the outside world, blocking unauthorized traffic. Intrusion detection systems monitor network traffic for malicious activity and alert administrators to potential threats. VPNs create secure, encrypted connections between devices, allowing users to access the network remotely without compromising security.

File and print services are essential functions provided by a network operating system. A NOS allows users to share files and printers across the network, making it easy to collaborate and share resources. File servers provide centralized storage for documents, images, and other data, while print servers manage print jobs and ensure efficient printer utilization. These services streamline workflows and improve productivity by making it easy for users to access and share resources.

The history of network operating systems is closely tied to the evolution of computer networking. In the early days of computing, operating systems were designed to run on standalone machines. As networks began to emerge, operating systems needed to be adapted to support network communication and resource sharing. One of the earliest network operating systems was Novell NetWare, which gained widespread popularity in the 1980s and 1990s. NetWare provided file and print services, as well as directory services for managing users and resources.

As the internet gained popularity, TCP/IP became the dominant networking protocol, and operating systems like Windows NT and Unix began to incorporate native support for TCP/IP. These operating systems provided more comprehensive networking features, including support for routing, firewalls, and VPNs. Today, modern network operating systems like Windows Server, Linux, and macOS Server offer a wide range of features for managing and securing networks of all sizes.
