Overview

This 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 description

It 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.

Overview

These files are commonly termed as ‘ping' and they store the raster files using lossless compression. It came into existence in order to replace the GIF file format as they both have the ability to show transparent backgrounds. Furthermore, it was an enhanced and improved version of Graphics Interchange format. It supports different types of photos. The first one is palette-based photographs that can either have palettes of 24-bit RGB or 32-bit RGBA colours. Second is grayscale images which may or may not have an alpha channel for transparency. Lastly, there is a full-colour non-palette which is based on RGB/RGBA pictures. There is one limitation of this type. It does not support animation like GIF. Besides this, it is non-patented which means there are no copyright limitations.

Technical description

The expanded features like 8- bit channel for transparency and 24- bit RGB support make PNG more popular. The files stores in this format allow the fading of colours from opaque to transparent which is not present in the preceding format. CMYK does not offer support to this extension as it was developed for transferring of files over the internet, not for professional-quality print graphics. It stores information like textual comments, integrity checks and encoded basic pixels in its extensible structure of chunks. It always starts with an 8-byte signature followed by a series of chunks. A chunk furthermore comprises of four parts- length (4 bytes), chunk type (4 bytes), chunk data (length bytes) and CRC- Cyclic redundancy checksum or code (4 bytes).
