Internet and Web

Web services typically maintain three categories of data: shared data (accessible across all users/sessions), pre-session data (initialized before a session begins), and temporary data (exists only during a specific session or transaction).

Web services fundamentally combine XML for structured data representation with HTTP as the underlying transport protocol. While SOAP is commonly used with XML and HTTP, the core combination that makes web services work is XML (for message formatting) and HTTP (for message transport).

The AppletStub interface serves as the communication channel between an applet and its browser environment. It provides methods like getParameter(), getAppletContext(), and showStatus() that allow the applet to interact with the browser and retrieve contextual information.

In Java AWT, the Applet class directly extends Panel, making Panel its immediate superclass. The class hierarchy is: Applet -> Panel -> Container -> Component -> Object.

FontMetrics is a specialized class that provides font measurement data like ascent (distance from baseline to top of characters) and descent (distance from baseline to bottom). The Font class itself represents the font but doesn't provide these detailed metrics.

XML is the standard format for encoding and decoding data in web services, providing a structured way to represent information. SOAP (Simple Object Access Protocol) is the protocol used to transport this XML data between applications over networks. Together, they form the core of web service communication.

WSDL (Web Services Description Language) is an XML-based language that provides a standardized way to describe web services. It specifies the service's location, available operations, input/output parameters, and data types - essentially everything needed to interact with the service.

Net Etiquette are the rules that have developed as people have begun to communicate and interact on the Internet.

Domain names are used to identify one or more IP addresses. For example, the domain name microsoft.com represents about a dozen IP addresses. Domain names are used in URLs to identify particular web pages. For example, in the URL http://www.pcwebopedia.com/index.html, the domain name is pcwebopedia.com.
