Study Notes
Computer Networks
- Networks connect multiple computers for resource sharing and communication.
- Connections can be wired, optical, or wireless.
- Two main network types are Local Area Networks (LANs) – small areas (e.g., a building).
- Wide Area Networks (WANs) – large areas (e.g., cities, countries).
- Networks use nodes (computers, servers, or networking devices).
- Nodes have unique network addresses.
- Communication protocols, like IP, are essential for data exchange.
- Network applications include internet access, file/printer sharing, email, and instant messaging.
