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.
