I have just started learning about network topologies, but there are a lot of confusion about different types of network topologies i have learnt so far.

First of all, BUS topology. If i have like 100 PCs in the same wire connected using BUS topology, and the network connection speed is 100Mbps, then each PC will have a connection of 1Mbps, right ?

With the same scenario, if i connect those 100 PCs using STAR topology, then each PC will have a connection of 100Mbps ?

Then with the TREE topology, i divide the system into 10 sub-system (10 tree branches) , each branch has 10 PCs, then i will have other 10 small "BUS-topology" networks each one will have a connection of 10Mbps and therefore each PC will also have 10Mbps ?

And the last one is RING topology, 100 PCs, each PC will have 100Mbps connection ?
