Doc (an abbreviation of document) is a file extension for word processing documents; it is associated mainly with Microsoft and their Microsoft Word application. Historically, it was used for documentation in plain-text format, particularly of programs or computer hardware, on a wide range of operating systems. Almost everyone would have used the doc file format, whenever you write a letter, do some work or generally write on your PC you will use the doc file format. It was in the 1990s that Microsoft chose the doc extension for their proprietary Microsoft Word processing formats. As PC technology has grown the original uses for the extension have become less important and have largely disappeared from the PC world.
Early versions of the doc file format contained mostly formatted text, however development of the format has allowed doc files to contain a wide variety of embedded objects such as charts and tables from other applications as well as media such as videos, images, sounds and diagrams. doc files can also contain mail merge information, which allows a word-processed template to be used in conjunction with a spreadsheet or database.

HTML5 is the fifth revision of the HTML standard, it's main aims are to improve the support for the all types of multimedia with the intention to keep it readable by both humans, computers and all devices. HTML5 has become the adopted standard following Apple CEO Steve Jobs very open letter entitled 'Thoughts on Flash' where he concludes that 'Flash is no longer necessary to watch video or consume any kind of web content' and that 'new open standards created in the mobile era, such as HTML5, will win'.
HTML5 introduces new elements that are not present in previous versions of HTML. It is now no longer based on SGML, it is designed to be backwards compatible with previous older versions of HTML. HTML5 specifies scripting APIs that can be used with both Javascript and the Document Object Model (DOM). There are also a number of new APIs to include: Canvas Element for 2D drawing, Timed Media playback, Document Editing, Drag and Drop, Web Storage amongst others. HTML5 attempts to make semantic replacements for uses of generic elements e.g. footer,audio and video rather than div,span or object.
