|Layer||Layer 1 device; Physical Layer||Layer 2 device; Data link Layer|
|Device type||Multiport repeater.
Pass all information received to all connected devices. It creates unnecessary traffic.
Pass information only those devices need it. It avoids unnecessary traffic.
|Network||Use for smaller network||Use for larger network|
|Function||Connect a network, computers join in central hub||Join multiple computers together within one local area network (LAN).|
|VLAN||There is no VLAN function.||VLAN can be created and security can be applied.|
|Broadcast||One.||One broadcast domain.
By default, do not breakup broadcast domain.
|Forwarding||Broadcast all connected devices.||By default, do not forward packets to other networks like routers.|
|Bandwidth||Provides less bandwidth.||Provides more bandwidth.|
Collision occurs commonly.
No collision occurs in full duplex switch.
|Duplex||Half duplex||Half / Full duplex|
|Ports||Up to 12 ports||Up to 48 ports|
|Speed||Up to 10 Mbps||Up to 10 Gbps|
- Layer 2 device; Data link Layer
- Allow to connect multiple devices and port can be manged. Vlan can create & security can be apply.
- Do not breakup broadcast domain by default
- Do not forward packets to other networks like routers
- Providing more bandwidth for LAN users
- Only ‘Switch’ frames from one port to another within the switched network
- Use hardware address to filter a network
- Many collision domain
- One broadcast domain
- Layer 1 device; Physical Layer
- To connect network, join through central hub
- 1 Collision domain
- 1 broadcast domain
- Never full duplex
- Multi-port repeater
