Topic 2: LAN and the Internet (Basic)
A LAN connects computers within a small area, while the internet connects networks worldwide, letting us access information and communicate
Core concept
A LAN (Local Area Network) is limited to a small area, like a building, connecting a limited number of computers.
How it works
The internet is a huge network of networks, connecting millions of computers and devices across the entire world.
Why it matters
While a LAN might let students share files within a school, the internet lets us communicate with people anywhere in the world.
Key detail
