Need explanation for meta tags

Need explanation for meta tags

#1

I have been studying html, css, javascript etc. for over a year now and I still am not clear on the meta tags. I also see comments that say they are to fix IE. I also see links that say they make the page compatible with iphone and android. Is there a comprehensive article that explains all these things? Also, is there a standard head snippet that should go at the head of my html file?
