As I was using the term, yes.

What I did use in the '80s! :-)  Still do, occasionally; I have a
10Mb-only hub - not switch - that I use when connecting certain older
hardware, hardware that has twisted-pair but is too impatient for
modern Ethernet autonegotiation and decides carrier is down.  (Some of
them can be taught to be more forgiving, but I suspect some can't, and
it's easier and simpler in many cases to just use the hub.  Most such
hardware can't do better than 10/half anyway, and I rarely want to run
significant levels of traffic from two such at once, so it doesn't
really impair anything in practice.)
