What Vertical portal is
A portal that caters to consumers within a particular industry (sometimes called a "vertical industry"). Vertical portals, also called "vortals," use Internet technology to offer the same kind of personalization tools that portals do. Another kind of vortal caters solely to other businesses rather than to an industry's consumers. The B2C portal gave the B2B industry a model to work from, and now, most business-to-business sites bill themselves as portals. We like to define business-to-business sites as vertical portals because they deliver content and services focused on their particular niche. The term "portal" is getting muddied because although many sites call themselves portals they are, in fact, simply Web sites that use cookie and/or personalization technology (see: personalize).
The two essential components of a vertical portal are that it uses this kind of technology and caters to a specific industry. The two essential components of a regular portal are that it uses this kind of technology and provides a variety of news, media, and services.
The meaning of Java
Developed by Sun Microsystems, it is a programming language specifically designed for writing programs that can be safely downloaded through the Internet without fear of viruses or other harm to computers or files. Using small Java programs called applets, Web pages can include functions such as animations, calculators, and other fancy tricks. Java is a simple, robust, object-oriented, platform-independent, multi-threaded, dynamic, general-purpose programming environment. It is best used for creating applets and applications for intranets, the Internet, and any other complex, distributed network.
