A browser is a software application that allows users to access and navigate the internet. It interprets and displays web pages, enabling users to view text, images, and videos. Popular browsers include Google Chrome, Mozilla Firefox, and Microsoft Edge. Browsers also support various features like bookmarks, tabs, and extensions to enhance the user experience. When using a browser, users can enter a web address, known as a URL, to visit specific sites. Browsers communicate with web servers to retrieve content and display it on the user's device. They also provide tools for privacy and security, such as incognito mode and pop-up blockers.
