Why would network user connected via a hub experience network transmission problems with increasing number of user ?

A hub operates at the physical layer of the OSI model and uses a shared medium to transmit data to all connected devices. As the number of users connected to the hub increases, the amount of traffic on the network also increases. This can lead to network congestion and collisions, as multiple devices try to transmit data at the same time.

Additionally, hubs do not have the ability to segment network traffic or prioritize certain types of data. This means that all data packets are broadcast to all connected devices, regardless of whether they are the intended recipient. This can lead to inefficiencies and delays in transmitting data, especially as the number of users on the network grows.

Overall, a hub is not an ideal solution for networks with a large number of users, as it can lead to performance issues and network transmission problems as the network becomes more congested. Switches or routers are typically recommended for larger networks, as they can better manage and prioritize network traffic.
