The document discusses various types of HTML and web server controls including data controls for displaying data in tables, validation controls for checking user input, login controls for authentication, and web parts controls for customizing web pages. Web server controls enable visual representation of data and allow users to perform CRUD operations on a data source from the browser. Validation controls compare user entries to constant values for both browser and server-side checking. Login controls provide a GUI for signing in and out as well as changing passwords. Web parts controls allow customization of web page content, appearance, and behavior directly from the browser.
