Browsers and HyperText Markup Language (HTML)

The Five Most Common Browsers
Internet Explorer (comes with every Windows installation since Windows 95) - Microsoft product

Safari (comes with the Mac OS, but available for Windows) - Apple product

Google Chrome - Google product

Mozilla Firefox (comes with Linux, but is available for just about everything else, including Smart Phones) - Open Source
Open Source means that the programming code is freely available to everyone under a non-commercial oriented license.
Anyone may use it free for non-commercial purposes, with very few restrictions.
Everyone is encouraged to contribute to the improvement of the code.
Open Source grew out of the "Gnu" open source free software initiative among colleges and universities in the 1980's.
Opera
An outgrowth of Mozilla, under the same free software concept.
Up and Coming: Smartphone Browers packaged with the Smartphone operating systems.
HyperText Mark-up Language (HTML)
"HyperText" is text designed for a computer Web Browser with click-able links in it to another web page or media presentation.

The concept of a "mark-up language" comes from the old "mark-up" symbols human editors would use when proofreading a writer's manuscript.

In the context of a computer language, mark-up's are embedded text inside special symbols where are not shown to the viewer of the web page.

Here is the HyperText file that creates this web page, at exactly the point when I was writing this line as I created this web page: this page under development.
