What is a Web Browser

A Web browser is a software application that can be used to connect with, navigate, and display information on the World Wide Web.

These browsers may assist in downloading and uploading files, debugging programs and displaying multimedia content in addition to simply rendering HTML pages.

Some “Web browsers” are specifically designed for accessing particular types of information such as video or multilingual content.

The invention of the World Wide Web in 1990 by Sir Tim Berners-Lee spurred the browsers to access and display information across the Internet.

Since then, web browsers have become an integral part of the daily life on both desktop computers and mobile devices connected to Internet – especially since Mosaic was released (1993) which later became Netscape Navigator (1994), Internet Explorer (1995) and finally Google Chrome (2008).

How a Web Browser work?

A web browser is a software program for retrieving, presenting, and traversing information resources on the World Wide Web. An information resource is identified by a Uniform Resource Identifier (URI) and may be a web page, image, video or other piece of content. Hyperlinks present in resources enable users easily to navigate their browsers to related resources.

Browsers are able to render HTML text and display pictures and other multimedia Web content onto a screen. They may also have the ability to store bookmarked pages in a cookie file or add other bookmarks, tags or favorites.

The major web browsers are Firefox, Chrome, Safari, Internet Explorer and Edge. As of February 2018 Firefox is the most popular browser with 55% of users globally.

More recent statistics show that the most popular browser is Google Chrome with 62.23% of users globally.

Browsers are making use of accelerate page loading through rendering web pages progressively as well as prefetching Web resources in the background for faster browsing.

A significant difference between browsers lies in their support for HTML, XML, and cascading stylesheets (CSS). The majority of browsers today have steadily improving support for HTML5, CSS and other web standards.

History of Web Browsers

The first web browser was called WorldWideWeb, made by a British scientist. The first widely available browser was Mosaic, a revolutionary program with a graphical interface and built-in email so people could browse the internet without knowing about html. Mosaic was invented in 1994 by a student at the University of Illinois named Marc Andreessen.

In 1995, Andreessen brought his invention to the company Netscape Communications Corporation, who released it as Netscape Navigator.

In 1996 Internet Explorer was introduced under Microsoft’s Windows operating system and then came Mozilla Firefox in 2003. Google Chrome came out in 2008 and Apple Safari is from 2007. In the present day, the world’s most used web browser is Google Chrome.

Common Features of Web Browsers

  • Email clients.
  • Make your browser’s extensions and addons.
  • Search the internet anonymously.
  • You own the data you store on your browser.

Functions of Web Browser

The browser has a number of functionalities which are required for the web browsing to be its full potential. These functions include the following:

  • The ability to load, render and interact with hypertext-based content on the World Wide Web.
  • A local storage system so that it can save websites locally, allowing you to return to them at a future date.
  • The ability to execute scripts in various languages like JavaScript, ruby and java script.
  • The capability of using CSS styling files for formatting content.
  • A graphic rendering engine to render web graphics.
  • Support for HTML5 and CSS3 standards.
  • The ability of using scripts to access a number of APIs on the browser’s system, such as Geolocation or Speech Recognition.

Components of a Web Browser

A web browser is a software application for accessing a website to retrieve a multimedia, hypertext and/or hypermedia information. The components of a web browser are:

  • A graphical user interface (GUI) to display the web page you’re viewing. This includes text input boxes, buttons to load pages, scrollbars for scrolling down the page, and an address bar to type in the URL.
  • An HTML parser that interprets the HTML code from the page into something that you can see on your screen. It takes all of those tags and turns them into text and images.
  • JavaScript interpreter which reads different types of JavaScript scripts. These scripts may make a certain change or give a certain animation effect, such as scrolling text, adding/removing items from your cart, etc.
  • A set of routines to communicate with the server hosting the website. This may be for either downloading a page or submitting information to the web site (in which case it will download a new page). For a form submission, this takes the data you typed into a form, and makes a connection back to the web server so that it can send a request for another page.
  • A rendering engine to display all of this information in a graphical format. This takes the HTML and any associated scripts and draws them onto your screen as text, images, or multimedia.
