1. What is the Web?
The web is a system that allows computers to communicate and share information over the Internet.
Key components:
-
Client: Your browser (Chrome, Edge, Firefox)
-
Server: The computer that stores websites and sends them to clients
-
Internet: The network connecting clients and servers
-
Analogy:
Think of the web like a library:
-
The server is the library with all the books.
-
The client is you visiting the library.
-
The Internet is the roads you travel to get there.
How Browsers Work
A browser fetches and displays websites using:
-
URL (Uniform Resource Locator): The web address, e.g.,
https://www.example.com -
HTTP/HTTPS: Protocols used to request and transfer data securely
-
Rendering Engine: Converts HTML, CSS, and JS into what you see on the screen
Example:
You type “https://example.com” → Browser sends request → Server responds → Browser renders page
Modern update:
-
HTTP/3 is faster than older versions and reduces delays.
-
Edge computing allows servers closer to users for faster loading.
3. Developer Tools
Tools to help you build and debug websites:
-
Browser DevTools: Inspect HTML/CSS, debug JavaScript
-
Code editors: VS Code, Sublime, or WebStorm
-
Version control: Git and GitHub for managing your code
Checkpoint: Open Chrome DevTools → Inspect any website → Change a color in the CSS and see the effect live.
