Answer 1

The parser corrects your mistakes, it will also display tags that don't exist and add quotes if they are missing from attributes etc...
But that varies from browser to browser that's why we follow the safe practices.

Answer 2

HTML files have to be read and converted to graphical output, the parser is breaking down the syntax and making html browser-readable.
