A web portal is:\nA Web portal is a site on the World Wide Web that typically provides personalized capabilities to its visitors, providing a pathway to other content. It is designed to use distributed applications, different numbers and types of middleware and hardware to provide services from a number of different sources. In addition, business portals are designed to share collaboration in workplaces. A further business-driven requirement of portals is that the content be able to work on multiple platforms such as personal computers, personal digital assistants (PDAs), and cell phones.\n\nA search engine is:\nA search engine or search service is a document retrieval system designed to help find information stored on a computer system, such as on the World Wide Web, inside a corporate or proprietary network, or in a personal computer. The search engine allows one to ask for content meeting specific criteria (typically those containing a given word or phrase) and retrieves a list of items that match those criteria.

Google and Yahoo are good. They both have different things that are difficult to compare. Google has the page rank fuction that helps if you're interested in web page publishing/pageviews and it is custimisitable. Yahoo toolbar seems easier to operate with, and has more functions too add. They both have antispyware protection.But still, I don't like too much toolbars in my browser...

A reference library told me that not all websites appear on all search engines or in the same order. I can't tell you why, except it helps to sometimes use more than one search engine.

Taking a big step back, a Web server serves pages for viewing in a Web browser, while an application server provides methods that client applications can call. A little more precisely, you can say that:\n\n    A Web server exclusively handles HTTP requests, whereas an application server serves business logic to application programs through any number of protocols.

Good question!...k lets me explain you the concept\nfirst : the concept in everysearch engine is that ..if you type any word in the searchengine (ex:google,yahoo)...search engine works by cataloging information contained on websites throughout the entire world wide web.search engine cannot catalogue specific information it uses ROBOTS AND SPIDERS(dont get confuesd with these concepts because ROBOTS AND SPIDERS are the softwares used in the search engine to fetch the information u want).....if u entering a word in the search engine (the softwares ROBOTS AND SPIDERS)will look after the word u search in three tags(TITLEtag,METAtag and ALT tag..i think you are familiar with These HTML tag)\n...are u satisfied with my answer

Information from Google:\n\nYour pages use frames. Google supports frames to the extent that we can. Frames tend to cause problems with search engines, bookmarks, emailing links and so on, because frames don't fit the conceptual model of the web (every page corresponds to a single URL). If a user's query matches the page as a whole, Google returns the frame set. If a user's query matches an individual frame on the page, Google returns the URL for that frame. The page is not displayed in a frame because there may be no frame set corresponding to that URL.\n\nIf you're concerned with the description of your site as seen by search engines, please read "Search Engines and Frames." It describes the "NoFrames" tag, which is used to provide alternative content. If, instead of providing alternative content, you use wording such as "This site requires the use of frames" or "Upgrade your browser," you're excluding both search engines and individuals whose browsers don't support frames. (For example, audio web browsers, such as those used in automobiles and by the visually impaired, typically do not deal with frames, which are a visual mechanism.) You can read about "NoFrames" in the HTML standard here.\n\n\nInformation from Yahoo:\n\nYahoo! Slurp (Yahoo's web crawler) has support for frames and makes an effort to crawl complex URLs such as those generated by forms, content generation systems, and dynamic page generation software.

A search engine or search service is a document retrieval system designed to help find information stored on a computer system, such as on the World Wide Web, inside a corporate or proprietary network, or in a personal computer. The search engine allows one to ask for content meeting specific criteria (typically those containing a given word or phrase) and retrieves a list of items that match those criteria. This list is often sorted with respect to some measure of relevance of the results. Search engines use regularly updated indexes to operate quickly and efficiently. Without further qualification, search engine usually refers to a Web search engine, which searches for information on the public Web. Other kinds of search engine are enterprise search engines, which search on intranets, personal search engines, which search individual personal computers, and mobile search engines. Different selection and relevance criteria may apply in different environments, or for different uses.\n\nSome search engines also mine data available in newsgroups, large databases, or open directories like DMOZ.org. Unlike Web directories, which are maintained by human editors, search engines operate algorithmically. Most websites which call themselves search engines are actually front ends to search engines owned by other companies

Search engines use very powerful or robust program codes which are called crawlers (or spiders), which crawl through the internet looking for new websites, if they find any, then they automatically catch the link to that site and include it in the storage directory. More powerful the crawler, better is the search engine.

I suppose what you called Search Engine Registration is the form provided by search engines to submit your URL.  Well, it's worth to try, but it can took months to get your website on search engines, especially Google and Yahoo. Good news is Google now has a service called Google Sitemaps. With that you can get listed in Google under 3 days. Check my sources, there is an article I wrote about it.\n\nSetting Keywords & Description should be done before you submit it to search engines. No, keyword & description is not important anymore to get your website on search engine. Now search engines like Google is more interested in how many websites out there on the Internet which has a link to your website. To know more about it you can download my free ebook about search engine optimization.\n\nThe difference between search engines and directory registration is that directory registration is reviewed by real human, while search engines is by machine.\n\nYou can focus only on Google and Yahoo, but Yahoo is harder to beat. And don't believe those paid services telling you they can submit on 1000+ search engines. Frankly, there are only about 200 of them, I suppose. The other may just a website full of links and can get your website blacklisted from the real search engines.

I prefer Google. It's faster, returns more relevant hits, and provides more options.

Web Portal:\nWeb portals are sites on the World Wide Web that typically provide personalized capabilities to their visitors. They are designed to use distributed applications, different numbers and types of middleware and hardware to provide services from a number of different sources. In addition, business portals are designed to share collaboration in workplaces. A further business-driven requirement of portals is that the content be able to work on multiple platforms such as personal computers, personal digital assistants (PDAs), and cell phones.\n\nWeb site:\nA website may be the work of an individual, a business or other organization and is typically dedicated to some particular topic or purpose. Any website can contain a hyperlink to any other website, so the distinction between individual sites, as perceived by the user, may sometimes be blurred.

Its better to take the time and go to each individual search engine and do it yourself than to use a quick submit website. That way you can be sure that it goes through for each search engine (Some search engines do not allow automated programs to submit URLs). And its free.

It depends on the search engine and it depends on the directory.\n\nA search engine will try to present you with the most relevant pages for the keywords you enter.  Unfortunately they don't always succeed.  Search engines will generally return you a greater variety of results.\n\nA good directory on the other hand won't try to return results from the entire internet.  It should instead be trying to get you the best results from the sites that it has in it.  And to get into the directory the site will normally have been reviewed by a human to make sure that it is what it says it is.\n\nSo when I'm searching if I just need any resource on a particular keyword then I'll be in a search engine.  If I'm looking for good sites in a particular category I'll probably be looking for it in a directory.\n\nThe key differences:\nSearch engines are automated and can be fooled.  Directories should be hand-edited and are hard to fool.  Search engines generally examine and return pages.  Directories look at sites.  Search engines can update within hours for new content.  Directories typically take days or months.  Search engines are usually simpler to use as you don't need to understand a directory structure.  Search engines are typically larger, directories tend to produce higher quality results, but have much reduced coverage.
