Web Browsers

A Web browser is a software that interprets and process data and information transferred from the network or Internet into a human understandable and usable form.

A web browser would send a request to the address specified by the user to the designated server in that address, the server processes the request and determines what data or document to fetch back to the browser, after that, the browser would process the data and interpret it into a an understandable form.

Web servers usually deliver static websites from HTML, CSS and JavaScript assets to the browser, but some are meant to dynamically change, such as FANDOM, that needs to change its article's contents every time it is edited, or when a new page is created, or when a blog post is published.

 * The Chromium Project is an example of a mass development general browser software, it's source code is used by Google Chrome and the Edge browser.
 * Internet Explorer uses it's own proprietary interpretation and code, although this method is now frowned upon, since the compatibility with other browser interpretations could be questioned or not synced, and even not load at all.
 * Other open source browsers could be found in online repositories and code hosting, some are built on Chromium, and some are made from scratch.
