The questions every beginner asks — answered in plain English.
Subnetting splits a large IP network into smaller, manageable pieces. It improves performance, security and address usage — for example, carving a /24 into four /26 networks for different departments.
TCP is reliable and ordered — it retransmits lost data (web browsing, email). UDP is fast and connectionless — it skips guarantees for speed (video calls, gaming, DNS).
A VLAN logically separates one physical switch into multiple virtual networks. It isolates traffic (like guest Wi-Fi from office LAN) without buying extra hardware.
A switch connects devices within the same network using MAC addresses. A router connects different networks using IP addresses — like your home router linking your LAN to the internet.
When you type a domain, your device asks a resolver, which walks the chain — root servers, TLD servers, then the domain's authoritative server — and returns the IP address to connect to.
Start with our Networking Fundamentals path: how data moves, IP addressing and subnetting. Then pick routing, security or wireless based on your goals.
