What is a Bridge in Computer Network and how does it work?
Direct Answer
Explains the function of a network bridge in connecting segments and filtering traffic.
Why Interviewers Ask This
Bridges are foundational for segmenting networks. Interviewers assess your understanding of collision domains and MAC address learning.
How to Answer This Question
Define a bridge as a device connecting two LAN segments. Explain how it learns MAC addresses and forwards frames selectively. Contrast with hubs and switches. Mention its role in reducing collision domains and improving network performance.
Key Points to Cover
- Segment connection
- MAC address learning
- Collision domain reduction
- Filtering mechanism
Sample Answer
A bridge connects two or more network segments at the data link layer, forwarding frames based on MAC addresses. It learns which devices are on which segment and only forwards traffic destined for the other side. This re…
Common Mistakes to Avoid
- Confusing with routers
- Ignoring frame filtering
- Omitting collision domain concept
