Difference between Switch & Hub:
Switch:
- Switches functions at Layer 2 Data Link Layer
- Forward / Filter decision using MAC address
- Loop Avoidance
- Address Learning
- Break-up collision domains
- witches make separate collision domains however a single broadcast domain
Hub:
- Hub functions at Layer 1 Physical Layer
- No Filtering
- Hub makes single collision domain and single broad-cast domain
- Build forwarding to all ports whenever signal is arrived
- No Addressing
