How the internet works. First of all, we have to understand what a web page is. A web page is a document that contains links that lead to other documents. It's a basic characteristic of web pages. Also, it has special words for markup like an h for titles or a table, a thread, a body, etc for tables. These type of documents could be considered as simple text docs which could be interpreted by the browser in a nice way. Actually, you could write this one by yourself in any text editor and then open it in your favorite browser locally.
