About Java, JavaScript and ActiveX

Java

Java is a programming language that allows you to create animated and interactive Web pages. A Java program used in a Web page is called a Java applet.

How Java Works

Java applets are stored on a Web server. When a reader displays a Web page containing a Java applet, the applet transfers from the Web server to the reader’s computer and then runs. Some Java applets take a long time to transfer. Java applets can run on many different types of computer systems, such as Macintosh, Windows and Unix.

Web Browsers

Before viewing a Java applet on a Web page, a reader must have a Web browser that can run Java applets. Most new Web browser can run Java applet.

Reasons for using Java

Web Page Enhancements: Most people use Java applets to enhance their Web pages. Many applets are used to display moving text or simple animation.

Interactive Web Pages: People often include Java applets in their Web pages to allow readers to interact with each other on the Web. Some Java applets allow readers to play games or chat with other people.

Programs: Java is also used to write complex programs such as word processing, spreadsheet and drawing programs. These types of Java applets are very large. Most people do not include this type of Java applet in their Web pages because the applets take too long to transfer.

JavaScript

JavaScript is a programming language that is mainly used for Web page enhancements, such as displaying scrolling messages and fading-in Web pages. Although the names are similar, JavaScript and Java have very little in common. JavaScript is easier to learn than Java.

How JavaScript Works

JavaScript instructions are placed in the HTML document.

Web Browser

Before viewing JavaScript on a Web page, a reader must have a Web browser that can run JavaScript instructions. Most new browsers can run JavaScript.

ActiveX

ActiveX is a newer technology developed by Microsoft to help improve your Web pages.

Reasons for Using ActiveX

ActiveX is commonly used in Web pages to add pop-up menus that instantly display a list of options. ActiveX is also used to include animated images and information from popular programs, such as Microsoft Word or Microsoft Excel, in Web pages.

Web Browsers

Before viewing a Web page that includes ActiveX features, a reader must have a Web browser that supports ActiveX. Microsoft Internet Explorer has built-in support for ActiveX. Some Web browsers, including Netscape Navigator, currently do not have built-in support.
