A web browser, often referred to as a browser, is a software application that allows users to access and navigate the World Wide Web. It is an essential tool for accessing websites, online content, and web applications. Here are the details of web browsers:
Key Features and Components:
- User Interface: Web browsers have a graphical user interface (GUI) that includes navigation buttons (back, forward, reload), address bars, bookmarks, and tabs for managing multiple open web pages.
