A web browser is an app with the primary function of retrieving information resources from the web, transforming them into human-readable content and displaying them on user’s devices.
The Browser Feature can be found in the Devices menu, and it’s one of the features that helps website owners strategize about UI/UX.
The most important thing about web browsers is that they transform pages that are delivered using Hypertext Transfer Protocol (HTTP/HTTPS), File Transfer Protocol (FTP), but also from email handlings (mailto:) and web files (file:), into content that otherwise would not have been readable by humans.
The first browser was created in 1990 and since then there has been a continuous evolution in this field, with more capabilities being progressively added to browsers.
As of the second quarter of this year, more than half of the world’s population has used a web browser.
These are the steps a browser takes in order to display content: After entering the URL, the browser will find the IP address for the domain name. Next, it will send an HTTP request to the server. After the server sends back a response, the browser will start rendering the page. The browser will also send additional requests for embedded objects (images, CSS) until the web page is fully loaded.
According to Wikipedia, here are some of the top browsers:
