Test Networking Basics, Topologies, Devices, Protocols & Media
Build networking knowledge from network types and topologies to routers, switches, Ethernet, protocols and transmission media. The goal is to understand how data moves, not simply memorize hardware names.
What Computer Network MCQs Test
Networking questions often ask you to connect a device or protocol with its role. A switch forwards traffic within a local network, a router connects networks, and communication protocols define rules for exchanging data. Topology questions focus on how nodes are arranged and how that design affects reliability or communication.
You will also see questions on LAN, MAN and WAN, wired and wireless transmission media, Ethernet, broadband technologies and common protocol concepts. A simple network diagram is one of the fastest ways to turn these terms into something memorable.
Network types and topologies
Compare LAN, MAN and WAN, then review star, bus, ring and mesh arrangements.
Devices and addressing
Understand what NICs, switches, routers, bridges, gateways and modems do in a network.
Protocols and media
Review Ethernet, TCP/IP-related concepts, DNS, DHCP and the characteristics of copper, fiber and wireless links.
Available Practice Sets
Use the descriptions to choose the topic you want to practise. New sets can be added here as the library grows.
Set 1: Network Basics, Devices and Protocols
Start with core networking terms and the jobs performed by common network hardware. This set covers network communication, LAN and WAN ideas, topologies, routers, switches, gateways, transmission media, IP-related concepts and basic protocols. It works well as the first check before moving into more detailed topology and performance questions.

Set 2 gives more practice with star, bus, ring and mesh topologies, plus routers, switches, bridges, gateways and modems. It also covers broadband and communication terms such as DSL and ISDN, along with network performance and connection concepts.

This updated 50-question set is arranged from basic concepts to more advanced networking. It covers telecommunications, LAN, MAN and WAN, client-server and peer-to-peer networks, NICs, Ethernet, collision domains, network devices, protocols, data communication rules and transmission media.

Place end devices, a switch, router and external connection on a simple diagram.
Start with the primary function before learning edge cases.
Distinguish physical media, local delivery, routing and application services.
Ask what happens to data from one device to another across the network.
Networking Terms Make More Sense as a Data Path
Imagine a laptop sending a request to a website. The device connects through a network interface, local traffic may pass through a switch or wireless access point, a router moves traffic toward another network, and higher-level protocols help identify destinations and services. Thinking through this path gives context to many networking MCQs.
Use the same approach for topology and media questions. Ask what the arrangement changes, how failure affects communication, and why fiber, copper or wireless links may be chosen. This is more useful than learning a device name without knowing where it fits in the network.
Networking Knowledge for Exams and Entry-Level Interviews
For exams, focus on definitions, comparisons and common protocol or hardware functions. For interviews, practice explaining why a switch and router are different, how a device gets network configuration, and what changes when traffic leaves the local network.
The network hub can expand with deeper areas such as TCP/IP layers, subnetting, security and wireless networking as new practice sets are published.
Frequently Asked Questions
What is the difference between LAN and WAN?
A LAN covers a limited local area, while a WAN connects networks over larger geographic distances.
What is the difference between a switch and router?
A switch primarily connects devices within a local network; a router forwards traffic between different networks.
Why should I learn network topologies?
They help you understand physical or logical arrangement, communication paths and design trade-offs.
Are protocols the same as network devices?
No. Devices are hardware or software components; protocols are rules and formats used for communication.
What should I study after basic networking?
Move into IP addressing, subnetting, TCP/IP behavior, routing, wireless networking and security.
