A web browser is an app whose primary function is to retrieve information resources form the web, transform them into human-readable content and display them on user’s devices.
A web browser (or browser for short) is a software application used for accessing the Internet.
The purpose of a browser is to fetch data and information from the World Wide Web and display it on devices. There are dedicated browsers for different types of devices (mobile, desktop) and all major web browsers have mobile versions.
The Browser Feature in Visitor Analytics can be found in the Devices menu, and it’s one of the features that helps website owners strategize about UI/UX.
Why are browsers important?
The most important part 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 be readable by humans.
The first browser was created in 1990 and since then there is a continuous evolution in this field, with more capabilities being progressively added to the browsers.
As of the second quarter of 2019, more than half of the World’s population has used a web browser.
How do web browsers work?
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.
