How a site reaches users — hosting, CDNs, content delivery, SSL, and latency.
Web hosting means renting space on an always-on server so your website is reachable on the internet 24/7. Here is what a host actually does and why your laptop cannot do its job.
A beginner-friendly tour of web hosting options. Compare shared, VPS, dedicated, cloud, and static hosting by cost, control, scaling, and effort, with a clear table and tips on when each one fits.
A beginner-friendly guide to CDNs (Content Delivery Networks): why distance slows the web, what gets cached at the edge, and how a CDN speeds up your site while protecting your origin server.
Follow a web page from the origin server to the screen: how a request finds the nearest CDN edge, what a cache hit versus a miss means, and how the browser turns the response into something you can see.
A beginner-friendly look at how web pages are produced and delivered: pre-rendered static files, server rendering per request, and client-side rendering — and the trade-offs for speed, SEO, and complexity.
A friendly, frontend-first explanation of what a web server actually is: the program that listens for HTTP requests and sends your files and data back. No ops jargon required.
What an SSL/TLS certificate really is, how Certificate Authorities and the chain of trust work, why your browser shows a padlock, and what expiry and renewal mean. A plain-English guide for beginners.
A beginner-friendly guide to ports and protocols. Learn what a port is, what common ports like 80, 443, 22, and 25 do, what HTTP, TCP, and UDP mean, and how host:port works in a URL.
A beginner-friendly mental model for web speed: what latency really is, how it differs from bandwidth, why distance matters, and how CDNs and caching make sites feel fast.
A beginner-friendly bird's-eye view of the last mile: you build, you deploy to a host, DNS points your domain at it, a CDN distributes it, HTTPS secures it, and users finally load your site.
