No, there are layer 1 hubs for Fast Ethernet, which were once a
reasonable alternative to switches for selected applications, until
switch prices came down. A Fast Ethernet hub does have collisions.
It is true that Fast Ethernet does not use (so far as I know) shared
cable such as 10Base5 or 10Base2.

It will not. Although if you have a 2500 series with two Ethernet
ports, there is a hack where you can combine the two with a Y-cable,
making one port transmit-only and one port receive-only, and connect
the joined end of the Y-cable to a full duplex switch port.
