If you want to test your internet connection without relying on a Flash or Java applet, one of these HTML5 tools may suit your needs.
Internet speed test apps have been around for a long time. Most of us have visited SpeedTest.net, SpeakEasy.net/SpeedTest, or our ISP's speed test site at one time or another to check our bandwidth. However, most of those apps use Flash or Java applets to conduct the speed testing. In the modern world of various platforms, only one solution will work on them all: HTML5. HTML5 is supported on all modern browsers -- Microsoft Internet Explorer, Google Chrome, Mozilla Firefox, and Apple Safari, as well as many others - which means your system doesn't need another piece of software to test your internet connection.
