I'm a beginner programmer and i know PHP, HTML, CSS, MySql, jQuery, BootStrap and have little knowledge on Web hosting. I'm trying to develop a website which will run as an OS(i.e. run Linux from the server) inside the browser. And whenever a user signs up, they are allotted with a username and password through which they can access their system(my website, their account). So, what are the things i should learn more or how can i implement it? Any help is appreciable.
