A web browser is an application that reads HTML documents, interprets them and displays them correctly on the screen.

We know various HTML tags make an HTML document. The web browser hides HTML tags but uses them to determine how to display the document on the screen.

The user inputs a Uniform Resource Locator (URL) into the address bar of the browser, such as https://resultuniversity.com/ and hit enter button.

The html document present at this web address is fetched by the browser using HTTP or HTTPs.

HTTP (Hypertext Transfer Protocol) is a set of rules for the transfer of the data between the browser and the web server. If the URL contains https, the connection is encrypted.

You can also fetch your HTML document from local storage, such as your desktop computer by typing document's file location in the address bar.

For example: file:///C:/Users/user/Desktop/myhtmlfile.html

When a user clicks back button, browser loads previously visited pages in sequence. When forward button is active and clicked, the browser loads the next page from the history of sites visited.
