I am a newbie in WordPress not totally but 6 months. I am confused with MULTISITE. I want to know that what is it, correct me if I wrong => is it a way to create a multi purpose site/theme easily means in default WordPress we can create a blog or a business site etc, but by using multisite functions that WordPress provide, I think it that we can create a multipurpose website easily again correct me if I wrong. Or is it used for something else if it is
- then what is that,
- what is the role of multisite functions,
- what the can do (means what they can provide so that I can make my site/theme better),
- are they useful for developers (means did I have to make my site/theme using these functions),
- we can make secure site/theme,
- the beginners need to also learn about multisite functions
