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 Virtual hosting
Virtual hosting is affordable for individual people's Web sites (vanity pages) and small businesses because this technology allows many sites to share the same server (there could be hundreds or thousands of them). The important thing is that no one else has access to your directories. However, unlike dedicated hosting, virtual hosting tends to have more traffic (from the co-located sites) and therefore less bandwidth per site and slower downloads.
