Study Notes

Network Devices Comparison

  • Router: Connects different networks. Handles routing data packets between networks, using intelligent routing algorithms. Operates at the Network Layer (Layer 3) and can segment networks. Manages and prioritizes network traffic using IP addresses for routing. Usually slower than switches due to routing overhead. Used for WAN connections and internet access.

  • Switch: Connects devices within the same network. Forwards data to specific devices using MAC addresses, learning MAC addresses. Operates at the Data Link Layer (Layer 2). Creates separate collision domains. Efficiently manages data flow to devices using MAC addresses for forwarding. Generally faster than routers due to direct data forwarding. Used for local area networks (LANs).

  • Hub: Connects multiple devices within a network. Broadcasts data to all devices. Unintelligent, no data filtering. Operates at the Physical Layer (Layer 1), and all devices share the same collision domain. No traffic management; can cause collisions. Does not use addressing. Slow, especially with many devices. Used for simple networks and legacy systems.
