Monocycles vs. Unicycles vs. Penny Farthings

Can someone explain the difference between a unicycle and a monocycle please?

I know I ride a unicycle, but I don’t know what a monocycle is.

A Penny Farthing has a large wheel and a small wheel (hence the name). Is a
Penny Farthing a monocycle (despite the 2 wheels)?

Has anyone here ridden a Penny Farthing? Are they much like riding a unicycle?
Are they hard to find?
