Difference between Distributed OS and Network OS

Difference between Distributed OS and Network OS

A distributed operating system (distributed OS) is an operating system (OS) in which processing and data are logically distributed across different networked computer systems. A network operating system (network OS) is a type of distributed operating system that enables multiple users to connect to a single centralized server, typically through a client-server architecture. In this tutorial, we will compare and contrast the two types of systems. We will also discuss the benefits and drawbacks of each approach. By understanding the differences between these two types of systems, you can make an informed decision about which one is best for your needs.

What is Distributed OS?

A distributed operating system (DOS) is software over computer networks that provides an environment for applications that can be run on multiple computers at the same time. It uses a client-server model in which each computer or process has its own copy of the operating system software and its own application software. The client-server model allows for the sharing of data and resources between computers on the network. Distributed operating systems are designed to provide a high degree of availability and performance. They are often used in mission-critical applications such as air traffic control and financial trading systems.

What is Network OS?

A network operating system (NOS) is a computer software system that provides the underlying base platform for initiating, controlling, and managing networked devices and services. In other words, NOS software is what enables hardware components like routers, switches, bridges, and firewalls to interact with each other and form the complex infrastructure of a functioning network. Cisco IOS (Internetwork Operating System) and Juniper JUNOS are two examples of widely-used NOS platforms. When planning and designing a network, it is important to select an appropriate NOS that will be able to meet the specific needs and requirements of the application or applications it will be supporting.

Difference between Distributed OS and Network OS

A distributed operating system is software over a collection of independent, networked, shared-memory computers. A distributed operating system manages all the resources of a network and provides users with transparent access to files and peripherals. In contrast, a network operating system is software that provides the capability for multiple computers to share information and files. It also allows users to connect to remote resources, such as printing or e-mail. Network operating systems are typically used in larger organizations where there is a need for central control and administration.


In conclusion, both network and distributed operating systems have their own advantages and disadvantages. It is important for businesses to understand the difference so that they can choose the right system for their needs.
