Network switches and hubs are fundamental components in wired networking infrastructure. While both devices connect multiple Ethernet devices, switches operate at Layer 2 (Data Link) of the OSI model with intelligent MAC address learning capabilities, while hubs function as basic Layer 1 (Physical) broadcast devices. Switches enable efficient point-to-point communication, reducing collisions compared to hubs. Their role in modern network architecture is critical for enterprise connectivity, data center operations, and industrial IoT deployments.
| Type | Functional Characteristics | Application Examples |
|---|---|---|
| Managed Switches | Support VLANs, QoS, SNMP monitoring, and port configuration | Enterprise core networks |
| Unmanaged Switches | Plug-and-play operation with fixed configurations | Small office/home networks |
| PoE Switches | Deliver power over Ethernet cables (IEEE 802.3af/at/bt) | IP camera systems |
| Core Switches | High-throughput backbone connectivity with redundant hardware | Data center aggregation |
| Access Switches | Edge network connectivity with basic security features | Corporate workstations |
| Active Hubs | Signal amplification with multi-port repeater functionality | Legacy industrial control systems |
| Passive Hubs | Simple physical layer connections without signal regeneration | Temporary network troubleshooting |
Typical switch architecture includes:
Hubs feature simpler construction:
| Parameter | Description | Importance |
|---|---|---|
| Port Density | Number of 10/100/1000 Mbps or 10/25/40/100 GbE ports | Determines scalability |
| Switching Capacity | Backplane bandwidth (bps) | Maximum data throughput potential |
| MAC Address Table Size | Number of supported device entries | Affects network scale and performance |
| Latency | Store-and-forward delay ( s) | Critical for real-time applications |
| PoE Budget | Total power delivery capacity (W) | Limits connected device count |
| Redundancy Protocols | STP/RSTP/MSTP support | Network fault tolerance |
