The first chapter knowledge:
1.C / S (Client Client / Server) and B / S (Browser Browser / Server). Web application refers to B / S-mode program, and B / S is more widespread use.
2.Web three of the essence: ** HTML (HTML5) ** language information docking, URL (URL link) for web unique positioning, HTTP protocol and HTML web page URL information to share information.
3. refer to static pages edited all the information will not change pages (static refers to code static, not static visual effects , nothing to do with .gif .mp4 like) the disadvantage of not only human-computer interaction information can be handled unilaterally, and difficult to maintain. In contrast, dynamic pages refers to the database and the outside world, each load will be based on external factors while the relative degree of change (such as bilibili, Youtube, etc., if the dynamic new posting messages or data push will be the big news on the alert for the page ) dynamic web pages interactive, easy to maintain.
4.JavaWeb three knowledge points: HTML used to design static web pages, CSS for detailed information about setting display HTML, making static pages more beautiful, JS / JavaScript for dynamic web pages, to achieve a certain degree of user interaction (such as Grease Monkey plug-in scripts, and many chrome extensions). (JavaScript essentially nothing to do with Java, but Java because it was more fire got up this name Minato heat)
5. Static Web program consists of HTML, CSS, JS composition, dynamic Web applications from the JSP (JavaServer Pages, used to implement web client request and server response), JDBC (Java Database Connectivity, refers to the use of the Java language and database to achieve docking technology), JavaBean (one kind of Java components), Servlet (Server applet, like applets) and other technology components.
