Shared and Switched Ethernet
🌐 Shared Ethernet In Shared Ethernet, all devices are connected to a single broadcast medium. This architecture typically uses Hubs, which transmit signals to all connected devices. Channel Sharing: Multiple devices share the same physical medium. If two devices attempt to transmit at the same time, collisions occur, causing network inefficiencies. Collision Domain: All devices within the hub are in the same collision domain, meaning they share the same bandwidth. Performance Considerations: Bandwidth Efficiency: Low due to collision overhead. Scalability Issues: As more devices are added, collision rates increase, further reducing throughput. Key Protocol: CSMA/CD Devices use Carrier Sense Multiple Access with Collision Detection (CSMA/CD) to avoid collisions. If a collision is detected, all devices involved retransmit their data after a random backoff period. ⚡ Switched Ethernet Switched Ethernet uses Ethernet switches instead of hubs, allowing devices to communicate without the risk of collisions. ...
