File categoryDocument file
Stands forHypertext to Markup Language
DeveloperWorld Wide Web Consortium and WHATWG
OverviewThis extension is predominantly used to design web pages which are displayed by different browsers such as Safari, Internet Explorer, Mozilla Firefox and Google; etc. Web browsers get the HTML document from a web server and in return, generate the document into multimedia web pages on a user's device. The source code can be viewed by choosing an option ‘View page source' (appears on right-click) from a web page or by using a shortcut that is ‘Ctrl + U'. In actual words, this format directs the browser on how to exhibit the words and images of a web page to the user. It may include images, audio, video and scripts as well.
Technical descriptionIt helps to create a structured document where semantics are used to display text such as paragraphs, headings, hyperlinks, tables and quotes; etc. The building blocks of HTML pages are their elements which are designed by tags using angle brackets. For example, <img /> and <input /> tags help to submit content into the page, <p> tag provides information about the document text, . Apart from this, the technologies that support this format are CSS (Cascading Style Sheets) and JavaScript, which is a scripting language. Here is a list of few basic elements or tags. <head> for metadata, <body> defines the body of the webpage, <h1> text header for creating a text title, <p> specify a paragraph, <img> to embed an image, <ul> to indicate an unordered list with no numerical order or bullet list and <div> used to define sections or divisions.

Stands forOpenDocument Text
DeveloperSun Microsystems
OverviewAnother name for ODT is Open document format for office applications i.e. ODF. It is a Zip compressed Extensible Markup Language (XML) based open format. It is a substitute for Microsoft’s office and used for creating spreadsheets, charts, presentation and other word processing documents. As it is an open software that is why there is no need to get a license, it is free of cost. A number of files and directories that have binary content can be compressed using ZIP's lossless compression and which in result lessens the size of the file. In opendocument, there is one advantage of the separation of concerns which means, there can be distinct sections that address information separately of varied type. It may include content, styles, metadata and application settings as well.
Technical descriptionBased on the Sun Microsystems specification for OpenOffice.org, it was created by a technical committee under the OASIS (Organization for the advancement of structured information standards) association. However, the original developer was StarOffice which intended to provide open software for office documents. It was also released under the ISO/IEC international standard ISO/IEC 26300:2006 standard. Furthermore, there are many extensions that are used in Opendocument. This includes .odt and .fodt for word processing documents, .ods and .fods for spreadsheets, .odp and .fodp for presentations, .odg and .fodg for graphics and finally .odf for formulae in mathematics. Besides this, this format is available both as free and proprietary software. AbiWord, Adobe Buzzword, Microsoft office-2003, 2007, 2010, 2013, 2016 and 2019, LibreOffice; etc are few examples of softwares that either fully or partially support this format.
