Study Notes
A Local Area Network (LAN) connects computers and devices within a limited geographical area, like a building, allowing high-speed data transfer and shared resources. Example: School networks connect computer labs and libraries.
- Peer-to-Peer Network — a network where all computers have equal status and share resources directly. Example: Small home networks with 2–10 devices.
- Client–Server Network — a network with dedicated servers providing services to client computers, offering centralised control and security. Example: Large businesses with centralised management.
- Server — a powerful computer providing services and resources to clients on a network. Example: File servers storing and managing data centrally.
