A few of us at Google created WhatBrowser.org to help teach people about web browsers. We wanted to show people that they have a lot of choice in browsers, since we noticed that most people were using the browser their computers came with.
How do browsers and the web actually work? What is HTML5-or HTML, for that matter? What do terms like "cookies" or "cloud computing" even mean? More practically, how can we keep ourselves safe from security threats like viruses when we're online?
