Ethernet Hub : What is it?
| Ethernet hubs, also called concentrators, connect computers in an Ethernet network using RJ-45 or twisted pair cables. They allow computers in the network to exchange data and share an Ethernet connection. They consist of two or more ports connecting each computer to a router or central network device, and indicator lights showing the connection status of each port. Most hubs also have recovery capabilities that detect connection problems, such as data collisions, and automatically disconnect the source port to isolate the problem. This makes them more efficient than coaxial Ethernet connections, where one faulty device can shut off the entire network. |

Kinds of Ethernet Hubs include the following: |
Passive Ethernet hubs
- Passive Ethernet hubs send data from one port to all other ports in the network.
- They are prone to data congestion and collision, which slows down the connection.
- They are ideal for small homes and offices using only a few computers.
Active Ethernet hubs
- Active Ethernet hubs reroute incoming data packets to specific destination ports, limiting the risk of collision to a single connection cable.
- They usually come with cache buffers, which save data packets for recovery in case of collisions.
- They have less data traffic and allow smoother connections than passive Ethernet hubs.

Number of ports: Choose an Ethernet hub that can connect all the stations in your network. Make sure there are enough ports to accommodate all computers. For small businesses, choose a model with more hubs than you currently need to allow for network expansion.
Security: Choose an Ethernet hub with a built-in firewall to keep harmful data from entering computers through the network. This is useful for large office and wireless networks, where there is heavier data traffic. Look for one that filters incoming data from common sources, such as email and peer-to-peer transfers. |
