Generations of Ethernet
Traditional Ethernet (802.3)

Categories of traditional ethernet
10Base5
10Base-T
10Base-FL
Network Ethernet bridging
Collision Domains
Switched Ethernet
Full Duplex switched Ethernet
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
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
1000Base-T implementation
