Give brief comparison of broadcast, unicastand multicast?

In broadcast the message is transmitted from one to all , in uni cast we have one to one transmission and in multicast we have transmission from one to many.

Explanation:

If we take the example of a simple messaging application it will be clear. If a message is exchanged between one person to another, then it is uni casting. If a person sends a message to all the persons in his contact list then it is broadcasting and  if a person sends messages to select persons in his contact list then it is multi casting. In multi casting management of the group is required regarding who can receive messages which is not required in broadcasting.

okay, so i know we just goofed around in that chat, but ive been like genuinly depressed, like medically depressed for almost 4 years now. i had my first panic attack when i was 8. i woke my mum up and told her i felt like i was in a dream. like i was a goldfish in a bowl, looking at all these things going on around me and feeling . tiny. wort hless. and i now am now 17 y/o. i still feel those emotions daily. life used to go by so quick.like every day i would wake up and just like want to go back to bed cause i always felt like i was in the wrong place. i guess looking back, i was in the wrong state of mind. i took a expensive like nice trip to whyoming with my grandfather and ha ted it. like idk why. i would have loved it now, but i found myself writing in a journal everyday because i would forget what happened the day before, couldnt remember what i ate for like the previous meal. just my memory left me for the week i was there. worst feeling ive ever experienced.
