What Is A Web Browser

    Browser is the application program which provides the means of viewing and interacting with all information in the world wide web. A Web browser, also known as Internet browser or just a browser, is a software application that allows individuals to access the World Wide Web. A web browser is a client-side program that uses HTTP (Hypertext Transfer Protocol) to make requests of web servers across the Internet on behalf of the browsers users. When the user requests a Web page from a specific Web site, a Web browser fetches the required content from a Web server, then displays the page on the users device.

    To render the information graphically on your device, web browsers have a user interface, also known as a front-end, in which you can click, scroll, and move through webpages and websites. The most common features of a web browser include the browser window itself (also called UI), the navigation and address bars, and options for viewing your history, settings, and other tools. Web browsers are used mainly to view and access websites online, and also for other content created using languages like Hypertext Markup Language (HTML) and Extensible Markup Language (XML).

    The primary purpose of an Internet browser is to convert code computers use to build websites into text, graphics, and other features of the webpages we are used to seeing today. When a web browser retrieves data from an Internet-connected server, it uses a piece of software called the rendering engine to convert this data into text and images. When the browser fetches data from a server, HTML converts that data to human-readable form, which is information displayed on a devices screen.

    When a browser visits the server to retrieve data, a Web address tells the browser where to search for each element described by HTML, which then tells the browser where to place it in a Web page. The browser gets back a file written in computer code, such as HTML or Javascript, which includes instructions for displaying the information on this page. Whenever we look something up online, the browser loads a webpage written in HTML, including text, links, images, and other elements such as style sheets and JavaScript functions.

    A web browser allows visiting websites and performing actions on them, such as signing in, viewing media, linking from one website to another, visiting a page from another, and printing, sending, and receiving emails, among many other actions. Internet browsers have evolved to become powerful tools that allow you to safely and quickly access the websites that you love. Many will use a web browser to access the world wide web these days, and it is seen almost as necessary for how many go about their everyday lives. It is interesting to note that while there is an emerging Internet of Things (IoT) phenomenon, with a wider variety of appliances connecting to the Internet, only mainstream devices such as cell phones and laptops are really using a designed web browser.

    The web browser is the most used preferred piece of technology in the average users toolbar, yet it is still evolving and developing to meet our modern Internet needs. Today, all of the popular web browsers are constantly fighting to dominate the internet, with Internet Explorer still holding Internet Explorers spot as the most used, and Mozilla Firefox just not too far behind. Microsofts Internet Explorer, which was the go-to browser at one time, has been discontinued, but developers are still maintaining Internet Explorer 11, which comes bundled with Windows 10.

    In 2015, Microsoft announced that Microsoft Edge will take over for Internet Explorer as the default browser in Windows 10, making Internet Explorer 11 the last release. Unlike Chrome, Safari, Internet Explorer, and Microsoft Edge, Firefox is an open-source browser created by members of the Mozilla Foundation community. In 1998, Netscape launched what became the Mozilla Foundation with the goal of creating a new browser using an open-source software model.

    After its launch, a number of browsers were invented that had different features such as Mozilla Firefox, Google Chrome, Safari, Opera, and others. Once Internet Explorer was integrated in Windows operating system, and since Windows started shipping as OEM software to other vendors, Internet Explorer rapidly replaced NetScape Communicator as the number one web browser, ending the first of so called Browser Wars. The first widely used and graphically friendly browser to contribute to popularizing the World Wide Web was NCSA Mosaic. There are a lot of different web browsers, but some of the more common ones include Google Chrome, Internet Explorer, Safari, Microsoft Edge, and Mozilla Firefox.

    Currently, Google Chrome is the most used browser worldwide, as well as considered to be among the fastest and safest. Created by Internet giant Google, Chrome is the most widely used browser in the United States, with Chrome computers and smartphone users viewing it as fast, secure, and reliable. One of the reasons why Firefox remains powerful may be that Firefox runs open-source software and has convenient tools for developers, making it easier for engineers and other web professionals to audit and upgrade their websites for improvements in security, privacy, and usability.

    All browser makers design their products to render images and videos as fast and as fluidly as possible, making it easier to get the most out of the Web. When you are browsing the world wide web, browser caches are data that it has downloaded, meaning that they save part or all of every page that you visit to your computer. The web browser pulls information from elsewhere on the Internet and displays it on your desktop or mobile device. Browsers work because each webpage, image, and video on the internet has its own unique Uniform Resource Locator (URL), which allows a browser to recognize a resource and pull it down from the webserver.
