i have a question which is quite simple but yet complicated for me my question is why do we use void, if it does not return anything to the compiler? if it is used for normal display it can also be done by what is called Console.Write() or Consol.WriteLine() and if i do not use void with my method then my compiler throws me an error. if i return a value say integer then i write public int fun() display of the result can also be done here then why is it so necessary to use void with a function and why so compiler throw us an error if v don't use void return type?

These questions were asked me in a technical interview: •If we deploy an application on multiple server (like database server, web server) then, each request should be redirected to proper server, then how you will handle it in your code? •How security pinholes will be handled in an application? •What things should be considered while writing a web application? •How will you do load/performance testing of web application? Which framework you will use for it? •How will you implement a cache for results which require a DB access? Please let me know how to write an web application considering all these points. I am not so much aware of architechural design of web application. Your guidelines will be helpful.
