Hub function
Hub function
A simple network device that connects multiple wires/cables without any signal processing, just repeating the signal to every port except the originating one.
Switch function
Switch function
A network device that operates at the data link layer (Layer 2) using MAC addresses to forward data only to the intended recipient port.
Router function
Router function
A network device operating at the network layer (Layer 3) that determines the optimal path for data between networks using IP addresses.

Study Notes
Hubs, Switches, and Routers
- Hubs are simple network connectors, operating on the physical layer (Layer 1) of the OSI model.
- They broadcast signals to all connected devices.
- Hubs are less expensive than switches and routers.
- Original hubs had a speed of 10 Mbps; modern internet hubs are 100 Mbps.
- Hubs are used in Local Area Networks (LANs).
Switches
- Switches operate at the data link layer (Layer 2) of the OSI model.
- They use MAC addresses to transmit data only to the intended recipient.
- They are more sophisticated and expensive than hubs.
- Maximum speeds vary from 10Mbps to 100 Mbps.
- Switches are also used in LANs.
Routers
- Routers operate at the network layer (Layer 3) of the OSI model.
- They use IP addresses to determine the best path for data transmission.
- Routers are more sophisticated and more expensive than switches and hubs.
- They have greater speeds, from 1-10 Mbps wireless and up to 100 Mbps wired connections
- Routers are used in LANs, Metropolitan Area Networks (MANs), and Wide Area Networks (WANs).
