A text-based web browser is a type of computer program that allows you to visit websites and see their content, but instead of using pictures and fancy graphics, it only uses words and symbols to show you what's on the webpage. Think of it like a book that only has words on a page, but you can click on links to go to other pages in the book. The browser uses special codes called HTML to show the words and symbols in a way that makes sense, and it also has special commands that you can type to do things like scroll up and down the page or search for specific words. Overall, it's like a simpler version of regular web browsing that doesn't need as much fancy technology to work.
