Study Notes
Computer Network Classification
- Networks are classified by geographical area and topology.
Geographical Span
- LAN (Local Area Network): Covers a small area like a home, office, or a few buildings.
- WAN (Wide Area Network): Spans a large geographic region, connecting multiple LANs, like a city or a country.
Network Topology
- Topology describes how network devices are connected.
- Bus Topology: Uses a central cable for all devices; network fails if the cable breaks.
- Ring Topology: Devices are connected in a circle, forming a continuous data path.
- Star Topology: All devices connect to a central device; network fails if the central device breaks down.
Network Components
- Protocols: Rules governing communication.
- Data (messages): Information exchanged.
- Transmission Devices: Devices facilitating data transfer (e.g., routers, switches).
- Transmission Medium (channel): The physical path for data transmission (e.g., cables, wireless).
