❓ Frequently Asked Questions
What is a computer network?
A group of devices connected to share data and resources using agreed‑upon rules and technologies.
What’s the difference between a router and a switch?
A router connects multiple networks and routes traffic between them; a switch connects devices within a single local network and forwards frames using MAC addresses.
What are IP addresses and subnetting?
An IP address uniquely identifies a device on a network; subnetting divides a network into smaller parts with a subnet mask to improve efficiency and security.
What is a network protocol?
A protocol is a set of rules that governs data formatting, signaling, and transmission so devices can communicate (examples: TCP/IP, HTTP, DNS).
