Network Ethernet bridging

Collision Domains

Switched Ethernet
![Page 15: CIT 307 Online Data Communications Local Area Networks Module 12 Kevin Siminski, Instructor.](https://reader035.fdocuments.net/reader035/viewer/2022062805/5697bff61a28abf838cbe218/html5/thumbnails/15.jpg)
Full Duplex switched Ethernet
![Page 16: CIT 307 Online Data Communications Local Area Networks Module 12 Kevin Siminski, Instructor.](https://reader035.fdocuments.net/reader035/viewer/2022062805/5697bff61a28abf838cbe218/html5/thumbnails/16.jpg)
Hub versus Switched Ethernet
Hub– Large collisions domains– Shared bandwidth for domains– 10Mb network realistically capable of support 5-6Mb
maximum Switched
– Collision domains are dedicated– Dedicated bandwidth– 100Mb network can achieve line rate– Majority of the devices today being implemented are based
on switched ethernet

Gigabit Ethernet

Gigabit Implementation
![Page 19: CIT 307 Online Data Communications Local Area Networks Module 12 Kevin Siminski, Instructor.](https://reader035.fdocuments.net/reader035/viewer/2022062805/5697bff61a28abf838cbe218/html5/thumbnails/19.jpg)
Implementation in networks
Can use traditional CAT5 or CAT5e twisted pair cabling
Can use Fiber optic cable but it is typically more expensive
Becoming the new standard in ethernet– vendors like Intel are embedding the NIC on their
new motherboards
