How Browsers Work

The basic function of a browser is extremely simple. Any programmer with a good knowledge of Perl or Java can write a minimal but functional text-only browser in one day. The browser makes a TCP socket connection to a web server, usually on port 80, and requests a document using HTTP syntax. The browser receives an HTML document over the connection and then parses and displays it, indicating in some way that parts of the text are links to other documents or images. When the user selects one of the links, perhaps by clicking on it, the process starts all over again, with the browser requesting another document. In spite of the advances in HTML, HTTP, and Java, the basic functionality is exactly the same for all web browsers.
