What is a Web Browser? – History, Functions, Work, Types, and Website Cookies

A web browser is a tool on your computer or phone that helps you explore the internet. It is a window to different websites where you can watch videos, read news, or play games. When you type a website’s name or click on a link, the browser understands and shows you what’s on that website. It transforms the website’s unique code into pictures and text you can easily understand. Think of it as your guide to the internet world. You can also save your favourite websites, open multiple pages at once, and add extra tools to your browser for more fun things.

    History of the Web Browsers

    Web browsers have an interesting history that began in the early days of the Internet. The first web browser, WorldWideWeb (later renamed Nexus), was created by Sir Tim Berners-Lee in 1990, allowing users to view and edit text-based web pages.

    A significant breakthrough occurred in 1993 with the development of Mosaic by Marc Andreessen and Eric Bina. Mosaic was the first graphical web browser, introducing features like images and making the internet more user-friendly.

    In 1994, Netscape Navigator, the first widely-used commercial web browser, was released by Netscape Communications Corporation. It gained immense popularity, reaching around 90% market share.

    Microsoft entered the scene with Internet Explorer (IE) in the late 1990s, sparking a “browser war” with Netscape. Meanwhile, the Mozilla project released Firefox in the early 2000s, known for its speed and security features.

    Google introduced Chrome in 2008, praised for its speed and simple design, ushering in a new era in web browsing.

    Browsers like Mozilla Firefox, Microsoft Edge, Apple Safari, and Google Chrome compete for users today. They focus on improving speed, and security, and supporting new web technologies to enhance our internet experience. The history of web browsers is a narrative of continuous improvement and competition, shaping how we explore the vast World Wide Web.

    How does a Web Browser Work?

    A web browser acts as a special window that allows you to explore and interact with the internet. When you type a website or click on a link, the browser requests information from the internet. The website’s computer returns files containing all the text, pictures, and special features to your browser.

    Your browser serves as a translator, understanding the website’s language, which comprises HTML, CSS, and JavaScript. It assembles everything to display the webpage on your screen, and if there are buttons or interactive elements, that’s the work of JavaScript.

    To make things quicker, browsers remember parts of websites you’ve visited, like pictures, so they don’t have to fetch them again. They also use cookies, which are like small notes, to recall your preferences and settings.

    In straightforward terms, a web browser is a tool that helps you view and interact with things on the internet. It communicates with websites, understands their language, and puts everything together for you to see and use.
