Computer Network MCQs with Answers and Networking Practice Questions
Build your networking knowledge with three published practice sets covering basic communication, network types, topologies, hardware, protocols, Ethernet and transmission media. Start with the fundamentals, then move into more detailed network design and data communication questions.
Learn Networking in a Clear Order
A computer network connects devices so they can exchange data and share resources. The first step is learning the basic language: nodes, bandwidth, LAN, WAN and transmission media. After that, network topologies and hardware become easier because you can see how devices are connected and how traffic moves.
Routers, switches, bridges, gateways and modems do different jobs. Protocols such as TCP, UDP, HTTP, DNS and DHCP provide rules for communication. Ethernet explains a common way devices communicate on local networks, while copper, fiber and wireless links provide the physical path.
Network types
Review LAN, MAN, WAN, client-server and peer-to-peer ideas and understand how network scale changes.
Topologies and devices
Compare star, bus, ring and mesh layouts, then practise routers, switches, bridges, gateways and NICs.
Protocols and media
Work with Ethernet, TCP/IP-related terms, broadband, addressing concepts and wired or wireless media.

Computer Network MCQ Sets
Each set has a different focus. Use the descriptions to choose the set that matches what you are revising.
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.

Which network set should a beginner start with?
Start with Set 1. It gives the broadest introduction to network types, devices, communication and protocol basics.
Which set is best for network topology MCQs?
Set 2 has a strong topology focus, while Set 3 also revises network types and architecture.
Do these questions cover routers and switches?
Yes. Routers, switches, bridges, gateways, modems and network interface hardware appear across the series.
Does the series include protocols?
Yes. The sets include common communication and protocol concepts, including Ethernet and TCP/IP-related topics.
Are these MCQs useful for technical interviews?
They are useful for entry-level concept review. For interviews, also practise explaining packet flow, IP addressing, switching and routing in your own words.
