Subject & Observable Unicast vs Multicast

What is Unicast Consider one sender and many receivers in unicast each receiver gets it’s own separate copy of data. If 100 different receivers are listening they all get separate copy of data. What is Multicast Consider multiple receivers listening to a sender then all get the same data from the source sender. Observables are Unicast. Subject is Multicast.

I can add code illustrations to demonstrate this behavior.
