Why do you need asynchronous programming in C#?

Question

.NET

Hello. Recently, in an interview, I was asked why asynchronous programming in C# is needed at all. I understand it more or less, but I blunted and did not answer the question. Moreover, even now I do not understand how to correctly and beautifully answer it. Can anyone help?

Answer 1

Asynchrony is needed so that the main "process" of the program does not block the execution of instructions. And he transferred control to another independent thread / process until the previous one responds with success about the successful completion of the execution and the readiness to continue following the code / instructions.
Goals:
- speeding up the program
- execution without blocking effects (including in the user interface)
- multitasking + multithreading

Answer 2

In these publications, in my opinion, it is well written about asynchrony in general
