Distributed System in Operating System

Distributed System in Operating System:


A Distributed System is a type of computer system in which various independent computers work together over a network to achieve a common goal. This system allows users to use multiple machines at the same time, making it seem as if they are working with only one computer. The purpose of a distributed system is to ensure better use of resources, greater functionality, and higher performance.

Definition of a Distributed System:

A distributed system is one in which multiple independent computers are connected via a network and act as an organized system. The main objective of these computers is to share resources, solve large problems, and give users the experience of working with a single computer.

Components of a Distributed System:

  • Nodes: The multiple computers in a distributed system.
  • Communication Network: Connects all the nodes.
  • Middleware: A software layer that facilitates communication and resource management between nodes.
  • Resource Management: Manages the sharing of resources like processing power, memory, and storage.

Types of Distributed Systems:

  • Client-Server Model: Server nodes store data and resources, while client nodes request access to them.
  • Peer-to-Peer Model: All nodes are equal and can act as both client and server.
  • Distributed Computing System: Different computers work together to solve a complex problem.
  • Distributed Database System: Data is distributed across different nodes.
  • Distributed File System: Files are distributed across different nodes, but appear to users as if they are in one location.

Advantages of a Distributed System:

  • Improved Performance.
  • Resource Sharing.
  • Fault Tolerance.
  • Scalability.
  • Parallel Processing.

Challenges of a Distributed System:

  • Network Reliability.
  • Security.
  • Data Coordination.
  • Software Complexity.
  • Failure Management.

Applications of a Distributed System:

  • Web-Based Applications.
  • Database Systems.
  • Scientific Applications.
  • E-Commerce and Banking.
  • Global Positioning System (GPS).
