How does Ethernet achieve its high bandwidth?
Ethernet achieves high bandwidth through various mechanisms:
- Data Framing: Ethernet breaks data into frames, each with a header, payload, and trailer. This structure allows for efficient data transmission.
- Collision Detection: Traditional Ethernet used a CSMA/CD (Carrier Sense Multiple Access with Collision Detection) method, which detected collisions and managed data flow accordingly.
- Switching Technology: Modern Ethernet networks use switches instead of hubs, allowing for dedicated communication paths between devices and reducing collisions.

- Fast Ethernet and Gigabit Ethernet: These iterations of Ethernet increased data rates, with Gigabit Ethernet offering up to 1 Gbps (1000 Mbps) speeds.
- Full-Duplex Communication: Ethernet can simultaneously transmit and receive data on the same link, effectively doubling the potential bandwidth.
