What Are the Disadvantages of Using Hubs?
Network hubs share all their bandwidth between every connected device. In a hypothetical situation, a 100-base hub has 100Mbps worth of bandwidth that it can share between four different computers that are sharing the connection. If one computer is sending a large file to another computer, it’s going to occupy all the bandwidth and give the other two computers slow network access. Network hubs are at a major disadvantage in this area against network switches that give each device its own dedicated bandwidth. For example, if two of eight computers connected to the same network switch are sending large files back and forth, the other six computers will still have full bandwidth available.
