To form a network with other nodes and add nodes to expand the connection, it is required to increase the nodes in a hierarchical format where the hub acts as a linking device in half-duplex mode for transmission and further receiving the data. There are certain multiple LAN cables that are connected to the hub with the help of some connector like RJ45, which acts as a mediator and has a connection with a range of wire approximately 100 m lengths.In contrast, the switch acts as an active hub which provides a lot of boost for generation and amplification of signal for establishing any successful connection.The Ethernet hub is considered quite a passive hub when it comes to boosting the signal and establishes a connection with other devices using the generation of the signal significantly.The ethernet hubs are still able to handle the port forwarding, but it cannot support the switching protocol while it is completely opposite in the case of the switch where the switch uses a switching loop which is useful in deploying and checking spanning tree protocol that helps in making the surrounding loop-free.The most important key difference between the ethernet hubs is it operates on physical layer whereas the switch operates on datalink layer of OSI.In ethernet hub, the number of ports for connection is very less compared to switch, which can support many numbers of ports as compared to ethernet hub thus useful.An ethernet hub makes use of a single collision in the domain, whereas the switch supports for different ports and different domains for collision because of which ethernet hub experiences more different domain collision.On the other hand, there is no concept of filtering when it comes to ether hub for forwarding but forwards one frame to each port uniquely. The switch supports filtering only for frames so that they are present only in particularly dedicated devices, especially for forwarded frames with the transfer of packets and bits.

Spanning tree implementation is not at all supported by the Ethernet hub, whereas it is supported by the multiple spanning tree in case of a switch.

The transmission mode used in the ethernet hub is half-duplex, whereas the switch, on the other hand, transmits data in bits in full-duplex.Whereas switch with a dedicated bandwidth is shared with other sets of ports. Ethernet hub has the capability to share bandwidth between the ports.
