A web browser is a software application that allows users to access and view websites on the internet. When a user requests a web page from a particular website, the browser retrieves its files from a web server and then displays the page on the users screen. The browser works as a compiler to render HTML, which is used to design a webpage. The purpose of a web browser is to fetch content from the World Wide Web or from local storage and display it on a users device. The information is transferred using the Hypertext Transfer Protocol (HTTP), which defines how text, images, and video are transmitted on the web. Some examples of web browsers include Google Chrome, Mozilla Firefox, Microsoft Edge, and Apple Safari. Its important to note that a web browser is not the same thing as a search engine, though the two are often confused. A search engine is a website that provides links to other websites, but to connect to a websites server and display its web pages, a user must have a web browser installed.
