Network Operating System vs. Distributed Operating System: Know the Difference
By Shumaila Saeed || Published on February 20, 2024
Network Operating System (NOS) manages network resources, while Distributed Operating System (DOS) manages a collection of independent computers appearing as a single system.
Key Differences
A Network Operating System (NOS) focuses on providing services to computers connected over a network. It enables resource sharing, including files and printers, among multiple computers. In contrast, a Distributed Operating System (DOS) integrates a group of independent computers into a system that appears to its users as a single coherent system. This approach differs in its intrinsic ability to create a unified computing environment from multiple nodes.

The Network Operating System is designed for robust network management and security. It facilitates communication, data sharing, and application operations across networked computers. On the other hand, a Distributed Operating System aims to provide a transparent and integrated computing experience across multiple machines. It achieves this by managing and coordinating tasks and resources across the distributed infrastructure as if it were a single system.

NOS typically operates in an environment where individual computers have their own user interfaces and operating systems. It enhances network functionality without fundamentally changing how each computer functions. Distributed Operating Systems, conversely, require a more homogenous environment where all participating nodes often run on the same OS, providing a more seamless and integrated user experience.

In a Network Operating System, users are aware of the multiplicity of machines. They might have to log into separate systems to access different resources. Conversely, a Distributed Operating System masks the complexity of the underlying network, presenting the entire group of computers as a single unified entity to the user.

Network Operating Systems generally offer easier setup and maintenance, suitable for less complex networks. Distributed Operating Systems, while more complex to set up and maintain, offer higher levels of resource utilization, scalability, and fault tolerance, suitable for more demanding and integrated network tasks.
