When you opened this page, your browser took dozens of steps in the blink of an eye: it found the address, shook hands with a server, encrypted the connection and brought everything back in small packets — sometimes from the other side of the world.
You see none of it — and that is technology doing its best work.
- DNS
- The internet’s phone book: it turns a site name into the IP address computers understand.
- TCP/IP
- Data is split into small packets that can take different routes and are reassembled at the destination.
- HTTPS
- The padlock means everything between you and the site is encrypted.
- Ping
- Even signals moving close to the speed of light lose milliseconds between continents — that’s why nearby servers feel faster.
