What is multicast ? I heard people say multicast but why isn't there unicast ?
What is Multicast? Why Not Unicast?

AI Thread Summary
Multicast is a networking protocol that allows a single packet of information to be sent to multiple users simultaneously, contrasting with unicast, where separate packets are sent to each user. This efficiency is particularly beneficial in scenarios like live streaming, where a DJ might have many listeners; using multicast significantly reduces the required upload bandwidth. Despite its advantages, multicast has seen limited development and business adoption, which has slowed its integration into mainstream networking solutions.

Correction: There is unicast! You are using it right now ^_^!
Multicast is a networking term used to mean a protocol in which one packet of information can be send to multiple users instead of sending x packets to all x users (unicast). Suppose your DJing at home and have 30 people tuning in at 64kbps, that's something like 2MB/sec upload on your side, which is not realistic. But while using multicast, this isn't a problem. You just need to send it once. Unfortunately, I haven't seen much development or business incentive with multicast and that's why it's a bit slow to be adopted by companies.
Edit: Oh, lookie what I found on Wikipedia :P

i am a cse student and as a second year student i started building apps. by sing chatgpt i am getting frontend files and backend files but i fail to connect those files. how to learn it and when i asked my friend he said learn about api keys. should i learn that or learn something new
I've tried to intuit public key encryption but never quite managed.
But this seems to wrap it up in a bow.
This seems to be a very elegant way of transmitting a message publicly that only the sender and receiver can decipher.
Is this how PKE works?
No, it cant be. In the above case, the requester knows the target's "secret" key - because they have his ID, and therefore knows his birthdate.
I tried a web search "the loss of programming ", and found an article saying that all aspects of writing, developing, and testing software programs will one day all be handled through artificial intelligence. One must wonder then, who is responsible. WHO is responsible for any problems, bugs, deficiencies, or whatever malfunctions which the programs make their users endure? Things may work wrong however the "wrong" happens. AI needs to fix the problems for the users. Any way to...
