Introduction to Distributed Systems Definition:

A distributed operating system is a collection of independent computers that appear to the users of the system as a single computer

A distributed operating system is a type of operating system that uses multiple central processors to manage hardware resources and serve multiple real-time applications and users.

Each system in a distributed operating system has its own memory and processor. Communications between the systems occur using various communication lines such as telephone lines or high-speed buses. This collection of systems is also known as loosely coupled systems as well as distributed systems.

In this image above, as you can see, there are multiple workstations/systems/nodes and they are all bidirectionally connected with a communication network, which could be a LAN / WAN, etc.

Types of Distributed Operating System

• Let's check out some of the types of distributed operating systems:
• Peer to Peer Systems
• Client-Server Systems
• Middleware
• N-tier
• Three tier
