A web browser, also known as an Internet browser, is a software application that allows users to access and view web sites on the internet. Web browsers are used to navigate the Internet, view web pages, and interact with web-based applications. Examples of popular web browsers include Google Chrome, Mozilla Firefox, Microsoft Edge, Safari, and Opera. Web browsers use protocols like HTTP, HTTPS, and FTP to request web pages from servers, render the content of those pages, and display them to the user.
