14 Questions
What is the main advantage of using a Switch over shared CSMA/CD communication?
Elimination of collisions
Why does a Switch open the door for full-duplex communication?
Due to the absence of collisions
What is the composition of the CAM Table in a Switch?
Memory storing MAC Addresses
How long does it typically take for a Switch to learn every MAC address of devices connected to it?
15-30 seconds
What distinguishes the MAC address learning process between a Switch and a Bridge?
Hardware composition vs software-based learning
What is the primary purpose of the Logical Link Control (LLC) layer in Ethernet?
To identify the network layer protocol being used in the frame
Which communication method is used when an Ethernet frame is sent to a specific destination on the network?
Unicast
What is the primary reason for the emergence of LAN switches in Ethernet networks?
To segment the network into smaller collision domains
In the context of network speeds, what does the term 'Mbps' refer to?
Megabits per second
Which Ethernet technology emerged in 2007, offering a maximum speed of 100,000 Mbps?
100 Gigabit Ethernet
What is the primary mechanism used by Ethernet to handle potential collisions on a shared medium?
Carrier sense multiple access with collision detection (CSMA/CD)
What is the purpose of the CSMA/CD protocol?
To provide a way for devices to detect and recover from collisions on the network
What is the main problem with using a hub in a shared CSMA/CD Ethernet network?
Hubs create a single collision domain, meaning that all devices connected to the hub share the same network bandwidth
How do bridges help to address the problem of shared CSMA/CD communication?
Bridges learn MAC addresses and effectively split the network into two collision domains, reducing the likelihood of collisions
