Networking

The internet is a global network of computers that communicate using agreed protocols to share data and services.

An IP address is a unique numerical label assigned to every device on a network, allowing data to be sent to the right destination.

A computer network connects devices so they can communicate and share resources. Understanding networks is essential for grasping how the internet, cloud services, and everyday communication work.

Data packets are small chunks that large messages are broken into for transmission across a network, then reassembled at the destination.
