Casting and its types in networking

This is a submission for DEV Computer Science Challenge v24.06.12: One Byte Explainer.

Explainer

Casting means sending data packets over a network.
Unicast is sending data to a single node in a network (one-one). Broadcast is sending data to all nodes in a network (one-all). Multicast is sending data to a group of nodes in a network (one-many).

Additional Context

I was learning about this from a youtube video and thought why not write this networking concept in this challenge?
