Question

Explain the following connectivity device: 

Hub

Answer 1

1. Some networks, such as ARCNET-based star topologies, utilise device hubs.
2. Hubs are connecting devices that allow network traffic to be centralized through a single connecting point by joining cables without the need for soldering.
3. It sends signals to the other network components and controls the network's cabling.
   A network connected to a hub is seen in the figure.
   
4. Hubs are of three types:
   1. Active hub
   2. Passive hub
   3. Switching hub
5. The active hub connects the network and improves signals besides dividing and retransmitting them. This hub has electronic circuits. 
6. A passive hub splits and transmits signals but cannot enhance them. This has no electronic components.
7. Switching hubs swiftly route signals between hub ports. It can replace a router.
