HTML and ASP are two very common languages in the Web programming world, both of which can generate Web pages. So what are the differences between them? This article will introduce to you the differences between HTML and ASP, so that everyone can have a simple understanding of HTML and ASP.
HTML
HTML stands for Hypertext Markup Language used for developing web pages and especially web design , is the simplest language for writing web pages. It is mainly written using HTML element tags, and is mainly composed of HTML elements, opening tags <> and closing tags >; the data between these tags is usually the content.
The main goal of HTML is to allow web browsers to parse and display content written between tags, and the purpose of these HTML tags is to describe the content of the page.
HTML can only write static pages, and website content cannot be managed using HTML. In order to implement dynamic pages, in addition to using HTML and CSS, you also need other things, such as: php.
In the picture above: The PHP script processes the data saved on the server, and the processed data is reflected to the user and site administrator as an HTML template.
ASP
ASP stands for Active Server Pages, often called Classic ASP or ASP Classic; it is a server A side-side scripting environment designed for dynamically generated web pages.
ASP is mainly used to create and run dynamic interactive Web server applications. It can combine HTML pages, script commands and COM components to create interactive web pages and powerful web-based applications; making it easier to develop and modify said web applications.
The difference between HTML and ASP
1. The essential difference
HTML is a client-side language that allows web browsers to parse and display content written between tags, allowing images and objects to be embedded into web pages.
ASP is a server-side language, which means that the code written will be sent to the server and some code will be returned based on the operation requested. It can use any scripting language to embed programming and server-side instructions into HTML web pages.
2. The difference between Web pages
HTML is mainly used to create static web pages; while ASP is used to design user interactive pages or dynamic pages
3. Differences in case
HTML is not case-sensitive; ASP is case-sensitive.
4. Differences in database connections
HTML itself cannot be connected to the database and requires the help of other languages. However, an ASP or ASP.NET page can connect to a database in order to derive its content.
5. Differences in browser requests
When the browser requests an HTML file, the server will return the file.
However, when the browser requests an ASP file, it will pass the request to the ASP engine; then, the ASP engine reads the file line by line and executes the script line by line. Finally, the ASP file is returned to the browser in plain HTML format.
