Computer Networks - Physical and Data Link Layer
You want to design a network where devices communicate using Ethernet frames but avoid collisions entirely. Which modern Ethernet technology should you choose?
You want to design a network where devices communicate using Ethernet frames but avoid collisions entirely. Which modern Ethernet technology should you choose?
hard📝 Application Q15 of 15
Step-by-Step Solution
Solution:
Step 1: Understand collision domains
Half-duplex Ethernet with hubs shares the medium, causing collisions; full-duplex with switches separates devices.Step 2: Evaluate options for collision avoidance
Full-duplex Ethernet with switches allows simultaneous send/receive without collisions. Wireless uses CSMA/CA, not Ethernet. Token Ring is a different protocol.Final Answer:
Full-duplex Ethernet with switches -> Option AQuick Check:
No collisions = Full-duplex + switches [OK]
Quick Trick: Switches + full-duplex avoid Ethernet collisions [OK]
Common Mistakes:
MISTAKES- Choosing hubs which cause collisions
- Confusing wireless CSMA/CA with Ethernet collision control
- Thinking Token Ring is Ethernet
