Distributed and Network OS

Distributed Sytem

• It is a collection of independent computers that appear to users as a single system

• These computers work together and communicate via network to share resources, data, and even task.

Characteristics of a Distributed System

• Resource Sharing

• Scalability

• Fault Tolerance

• Flexibility

• Data Accessibility

Types of Distributed System: Client/Server Systems

When clients request services, the servers will provide responses.

Ex: Google Search Engine

Types of Distributed System: Peer to Peer Systems

When the system works like both client and server shared resources directly.

Ex: Blockchain and Crypto Networks

Types of Distributed System: Cloud Computing Systems

The delivery of computing resources like storage all over the internet.

Ex: Google Cloud Platform

Types of Distributed System: Distributed File Systems

It allows files to be stored and accessed across multiple servers or nodes in a network.

Network Operating System

• A specialized operating system designed to manage and control resources in a networked environment, allowing multiple devices to communicate, share files, and access resources.

• A traditional OS manages a single computer ' s resources, while a Network OS coordinates activities across multiple connected computers.

Network OS Function

• Network Protocols and Services

• Network Security

• Network Administration

Network Protocols and Services: TCP/IP

Transmission Control Protocol and Internet Protocol

Network Protocols and Services: FTP

File Transfer Protocol

Network Protocols and Services: HTTP/HTTPS

Hypertext Transfer Protocol / Secure

Network Protocols and Services: SMTP

Network Security: IDS / IPS

• Intrusion Detection / Prevention System (IDS / IPS)

• Virtual Private Network (VPN)

• Firewall Protection

• Encryption

• Access Control

Network Administration

It refers to the overall process of managing, configuring, and maintaining network resources and services within a network operating system.

Network Operating System

manages communication and resource sharing between devices, while a Distributed System uses multiple connected computers to function as one system. Both are essential in understanding how modern systems operate efficiently across multiple devices.
