NETWORKING QUIZ 1

Network Operating System (NOS)

A specialized operating system designed to manage network resources, users, services, security, and communication among computers connected to a network.

Novell NetWare

An early network operating system that became the premier choice for local area networks (LANs) in the 1980s, specializing in file and printer sharing.[cite: 4]

Peer-to-Peer (P2P) NOS

A network architecture where all connected computers are equals (peers) with no dedicated central servers, and each acts as both a client and a server.[cite: 4]

Microsoft Windows for Workgroups

An example of a P2P NOS that allows individual computers to share resources and devices, such as printers and files, with each other.[cite: 4]

Client-Server NOS

A network architecture where network functions are centralized into one or more dedicated servers that manage shared resources, network security, and user access for individual client workstations.[cite: 4]

Microsoft Windows Server

A powerful client-server operating system designed to handle corporate networking, Internet hosting, databases, messaging, and hybrid cloud environments.[cite: 4]

Apple MacOS Server

Apple's proprietary server operating system designed to run on Mac hardware for easy file sharing, email hosting, and device management.[cite: 4]

Resource Sharing

A core NOS feature that enables multiple users to access and share data, storage space, and hardware like network printers from different connected machines

User & Directory Management

A core NOS feature that centralizes user accounts, provides authentication, and manages access rights and permissions using systems like Active Directory or LDAP.[cite: 4]

Network Security

A core NOS feature that protects system integrity through built-in firewalls, encryption support, and role-based access controls (RBAC) to block unauthorized access.[cite: 4]

Fault Tolerance & Backups

A core NOS feature that ensures network reliability and uptime through redundancy, disaster recovery, and data backup mechanisms.[cite: 4]

Performance Monitoring

A core NOS feature that tracks bandwidth usage, identifies traffic bottlenecks, and manages routing protocols for efficient data exchange.[cite: 4]

Scalability

A core NOS feature that allows administrators to easily add new devices, users, or applications to the network infrastructure without causing system disruptions.[cite: 4]

Multitasking

The ability of a NOS to handle many thousands of tasks simultaneously and run each service separately so that one failure does not affect others.[cite: 4]

Multi user

This allows several user to login into the system simultaneously

Hotplug support

A feature that allows the administrator to replace or upgrade most hardware devices without shutting down the system.[cite: 4]

Linux Distributions (Ubuntu Server, CentOS, Red Hat)

Open-source general-purpose enterprise servers favored for their security, flexibility, and cost-efficiency in web hosting, cloud environments, and data centers.[cite: 4]

Cisco IOS

The industry standard specialized enterprise hardware NOS found in most Cisco Systems routers and switches, offering precise control via a flexible command-line interface.[cite: 4]

Junos OS

A specialized enterprise hardware NOS developed by Juniper Networks that is heavily used in telecommunications, service provider networks, and large data centers.[cite: 4]

Cisco NX-OS

A highly scalable network operating system programmed specifically for Cisco's Nexus series of data center switches.[cite: 4]

NVIDIA Cumulus Linux

A robust, open network operating system that converts standard switches into highly flexible, programmable networking platforms for cloud-scale environments.[cite: 4]

SONiC (Software for Open Networking in the Cloud)

An open-source NOS developed by Microsoft for cloud data centers, built on the Linux kernel and using the Switch Abstraction Interface (SAI).[cite: 4]

Arista EOS (Extensible Operating System)

A Linux-based network operating system programmed for data centers and cloud networking that provides a single binary software image across all Arista switches.[cite: 4]

ArcOS

A microservices-based network operating system developed by Arrcus designed for multi-cloud, edge, and 5G networking.[cite: 4]

Google ChromeOS

A cloud-centric operating system designed to provide secure computing for endpoint devices like laptops, desktops, and kiosks, focusing on endpoint management rather than traditional switch/router functions.[cite: 4]

HPE Aruba OS

A NOS that powers Aruba’s campus, branch, and wireless networking solutions, focusing on unified wired/wireless management, security, and AI-driven analytics.[cite: 4]
