Stands for the "World Wide Web."
The World Wide Web is a subset of the Internet consisting of websites and webpages that are accessible via a web browser. It is also known simply as "the Web." While the terms "the Internet" and "the Web" are often used interchangeably, it is important to note that the Web is a collection of sites, documents, and resources that you can browse; the Internet is the network itself that also carries other types of data and traffic like SSH connections, FTP file transfers, online gaming, and email.
You can browse websites and other resources using a web browser. Early web browsers like Mosaic could only display text, while modern web browsers can display images, videos, and interactive elements. You can navigate to websites directly by entering a URL into your browser, or you can use a search engine to find what you are looking for. The Web can also help you access web applications, which are similar to desktop applications but run on a remote server and are controlled through the browser.
