Networking is the backbone of all digital communication. Three core components—IP, DNS, and HTTP are critical to how data moves across the internet. This guide introduces each concept and how they work together.
IP addresses uniquely identify devices on a network. There are two versions:
DNS translates human-readable domain names (like example.com) into IP addresses. It acts like a phonebook for the internet. When you visit a website, your computer queries a DNS server to resolve the domain.
HTTP is the protocol used to request and transfer web pages. It defines how messages are formatted and transmitted between clients and servers. HTTPS is the secure version using SSL/TLS encryption.
Try inspecting network activity in your browser's DevTools to see IPs and HTTP headers in action. Understanding these basics helps with debugging, security, and web development.
