Study Notes
- Switches in Ethernet networks only transmit frames to intended ports, not broadcast across the network.
- Routers act as gateways between LAN and WAN, making intelligent routing decisions based on routing protocols.
- Ethernet networks use a shared medium, leading to collisions handled by CSMA/CD protocol.
- Ethernet LANs have collision domains when simultaneous transmission by two hosts leads to collision.
- Wireless LANs follow IEEE 802.11 standard, with devices certified by the Wi-Fi Alliance for interoperability.
- IEEE 802 standards support LANs in SCADA systems, NANs in distribution networks, and HANs in consumer premises.
- Ethernet is widely used for wired LANs due to simplicity, ease of maintenance, and reliability.
- Ethernet devices include repeaters, hubs, bridges, switches, and routers, each operating at different layers of the OSI model.
