Due to Coronovirus (COVID19) applications are being converted to UDP to avoid Handshakes..!! This kind of jokes we are reading on social media.
Let's try to understand it.
How anyone can be effected with this virus ???? Simply by accepting it from others.
How TCP Works
TCP is how most of the web works. It's a web page like blog page sending and receiving data. It's 2 way protocol, there's handshake involved.
You request for data and that request is recognized and you get back data package.
So it's 2 way communication.
How UDP Works
UDP is opposite of TCP. It's like there's stream of data you are accepting without recognizing like live streaming. You are just accepting accepting accepting......
This is how it relates with Coronovirus.
