What is Network Operating System?

A Network Operating System (NOS) is a software program that enables two or more computers to communicate with each other and share resources, such as file servers, printers, and applications. The NOS manages the communication of data between all the connected computers, allowing them to exchange files and share information.The most popular NOSs are Microsoft’s Windows Server, IBM’s OS/2 Warp Server, Apple’s Mac OS X Server, Red Hat’s Linux-based Enterprise Server and Novell Netware. Each of these systems have different features that allow users to customize their networks based on their individual requirements. For example, Windows Server has a built-in web server while Linux-based Enterprise Servers offer a range of database management solutions.Network Operating Systems also manage network security by controlling which users have access to certain resources or areas of the network. It also allows administrators to audit user activity on the network by tracking login attempts and other activities such as file transfers or application usage. This feature helps prevent unauthorized access to sensitive data stored on the network. Additionally, some systems offer advanced encryption technology that provides an extra layer of protection for data stored in transit over public networks such as the Internet. Finally, a Network Operating System can be used to create virtual private networks (VPNs) which allow remote users secure access into an organization’s internal network from anywhere in the world without having to physically connect any cables or hardware devices. This type of system also allows businesses to set up sites across multiple physical locations while still maintaining one single point of contact for administration purposes making it easier for organizations with multiple offices in different cities or countries around the world to stay connected with one another. Overall then it is clear why Network Operating Systems are so essential when connecting multiple computers together offering greater flexibility in how those computers communicate with each other as well as providing increased security for both data storage and transfer across public networks like the internet.
