When accessing a website, what is typically the name of the default file being viewed?

The default file typically named "index.html" serves as the standard landing page for many web servers. When you access a website without specifying a particular file name—such as by entering just the domain name—the server automatically looks for a file named "index.html" in the root directory. If this file is present, it is delivered to the user's browser to be displayed. The convention of using "index.html" began because it provides a standardized way for web servers to designate the default page for a directory.

Other potential names, like "homepage.html," "main.html," or "default.html," can be used as landing pages by specific server configurations or web applications, but they do not have the same universal recognition and expectation that "index.html" has. Thus, "index.html" remains the most common default file referenced in web development practices.
