When you hit Post, your phone converts data into invisible radio waves that travel to the nearest router or cell tower.
When you hit Post, your phone converts data into invisible radio waves that travel to the nearest router or cell tower.
Inside the router: radio waves are caught, converted to digital data, then sent as light pulses through a cable to your internet service provider.
DNS translates human-readable names like tiktok.com into numerical IP addresses that computers understand.
The complete journey: radio waves leave your home, become light pulses in fiber optic cables, cross oceans, reach a server farm, and return the same way.
The server processes your request and pulls information from a database — prices, videos, account details — then sends it back as new packets.
It depends on what your site does. For a simple static page (your name, a photo, a joke), you just need a hosting company to store your files and a domain name so people can find you. Companies like GitHub Pages or Netlify host simple sites for free.
For interactive animations, you add JavaScript — a programming language that runs inside the visitor's browser. The server doesn't work harder; the visitor's device does the thinking.
For user accounts and saved data, you need backend code running on the server plus a database. Now you're renting computing power from a cloud provider like Amazon Web Services or Google Cloud.
For payments, you add a payment processor like Stripe. It handles the bank, the security, and the regulations. You never store anyone's card number — you just ask Stripe "did they pay?" and get a yes or no.
Your domain name comes from a registrar (like GoDaddy or Namecheap) — a separate company from your host. The registrar lets you fill in the DNS phone book entry: "this name points to this server."
