The internet, an integral part of our lives, operates through interconnected computers and data packets. Picture a vast network of virtual roads where data packets act as vehicles, delivering information to their destination.

Data transmission

When you click a link or send a message, your device breaks down the data into packets. Routers guide these packets along the best path.

IP addresses

Devices have unique IP addresses, like digital street addresses, ensuring data reaches the right place.

Domain names and DNS

Domain names are easier to remember than numbers. DNS translates them to IP addresses.

Servers and responses

Data packets reach the intended server, which processes requests and sends back relevant data.

Encryption and security

Modern websites use encryption for privacy, encoding and decoding data.

Internet exchange points

These are hubs where networks connect and exchange data, like major intersections.
