1. Overview of Apple Wide Web

The Internet isn’t just about data; it is an all-embracing association of humans who allotment information, interact, and communicate. From the point of appearance of its users, the Internet is a all-inclusive accumulating of resources–people, information, and multimedia.

The Internet is an inter-connected arrangement of networks, the Apple Wide Web is the “virtual” web bond these networks. Anniversary apparatus (or accumulation of machines – archetype ICIMOD computers affiliated to the net via V-SAT) on a arrangement has a altered “address” from which it can appeal and accept information. A Web “browser” is a applicant affairs that requests advice from added computers which briefly action as “servers” sending the advice aloft request. The Web has existed for a continued time, but its exponential use and advance began in 1995 if graphical Web browsers (like Netscape, Internet Explorer) became added popular. At ICIMOD, Internet Explorer is the broadly acclimated web browser. With these graphical web browsers, the Internet mainly web became “user friendly”, and humans began to advance and broadcast web sites and web pages. Hyperlink is the advantage of the web pages. Hyperlink is the aspect in a webpage that links to addition page/place in the aforementioned website or to an absolutely altered website. Typically, you bang on the hyperlink to chase the link.

There are billions of web sites on the net. With billions of web pages online, you could absorb a lifetime surfing the Web, afterward links from one page to another. Amusing perhaps, but not actual able if you are afterwards some specific information. One of the bigger problems we acquaintance is the adversity of award targeted/specific information. Breadth do you alpha from? Searching

Searching the Internet requires skill, luck and a little bit of art.

2. Before Starting the Search

The easiest way to acquisition advice is if you apperceive a web page Internet abode or URL (Uniform Resource Locator) such as ICIMOD home website. You can acquisition these addresses on business cards, email signatures, or newspapers. Artlessly blazon the URL in the browser’s abode box and hit the key. If you do not apperceive the URL, you’ll accept to acquisition it by analytic the Internet. In abounding cases, a simple seek on the name of an alignment aural a lot of seek engines will acknowledgment a absolute hit on their web site.

3. Accoutrement for Searching

There are abounding seek accoutrement available:

· Web Directories / Basal Library / Library Gateways

· Seek Engines / Meta-search engines

· Abysmal web databases

‘Web Directories’ (subject directory) are the repositories of advantageous web sites abiding into a hierarchical, subject-based structure. They crave humans to appearance the alone Web website and actuate its adjustment into a accountable allocation arrangement or taxonomy. Already done, assertive keywords associated with those sites can be acclimated for analytic the directory’s abstracts banks to acquisition Web sites of interest.

For searches that are calmly classified, such as vendors of sunglasses, the seek directories tend to accommodate the a lot of constant and well-clustered results. This advantage is about bound alone to those allocation areas already acclimated in the anatomy by that service. Yahoo, for example, has about 2,000 classifications (excluding what it calls ‘Regional’ ones, which are a duplication of the above allocation areas by geographic region) in its accepted taxonomy. The Accessible Agenda Project has about 590,000 categories and 5,142,051 sites. Some broadly acclimated web directories are:

Google™ Directory

Search engines basis anniversary plan aural all or allotment of documents. If you affectation a concern to a seek engine, it matches your concern works adjoin the annal it has in its databases to present a advertisement of accessible abstracts affair your request. Seek engines are best for searches in added difficult affair areas or those which abatement into the gray areas amid the accountable classifications acclimated by directories. But, seek engines are stupid, and can alone accord you what you ask for. You can sometimes get bags of abstracts analogous a query. Also, at best, even the bigger seek engines alone basis a baby atom of the Internet’s documents.

It is important to bethink that if you are application a seek engine, you are NOT analytic the absolute web as it exists at this moment. You are in actuality analytic a allocation of the web, captured in a anchored basis created at an beforehand date.

Popular seek engines currently are:

Google™

AltaVista

Meta-search engines do not clamber the web accumulation their own searchable databases. Instead, they seek the databases of assorted sets of alone seek engines simultaneously, from a individual website and application the aforementioned interface. Meta-searchers accommodate a quick way of award out which engines are retrieving the best after-effects for you in your search

It consists of pages which are not affiliated to by added pages, such as Dynamic Web pages. Dynamic Web pages are basically searchable databases that bear Web pages generated just in acknowledgment to a query.

4. Which Accoutrement You Should Use

If you’re analytic for accepted advice on accepted topics, use accountable (web) directories. You could aswell use in cases, breadth you do not apperceive any keywords accompanying to a subject

Use basal library/Library gateways if you are analytic for top superior advice sites on the Web. You can be adequately assertive that these sites accept been advised and evaluated by accountable specialists for their accurateness and content.

If you’re analytic for a altered or abstruse seek appellation or if you wish to accomplish an all-embracing assay of what’s out there in the Web on a specific subject, again use metasearch engines.

If you’re analytic for real-time advice or for dynamically alteration agreeable such as the latest news, buzz book listings, accessible airline flights, etc., again use abysmal databases (invisible or abysmal web.)

5. Building Your Seek Strategy

Your adeptness to acquisition the advice you seek on the Internet is a action of how absolute your queries are and how finer you use seek services. Poor queries acknowledgment poor results; acceptable queries acknowledgment abundant results. Seek after-effects are alone as acceptable as the concern you affectation and how you search. There is no argent bullet.

The advice professionals at the University of California at Berkeley acclaim a accelerating access to Web searching. Actuality is their stepwise arrangement of accomplish to follow, which we about endorse for alpha searchers:

1. ANALYZE your affair to adjudge breadth to begin

2. Pick the appropriate starting place

3. Learn as you go & VARY your access with what you learn

4. Don’t bog down in any action that doesn’t work

· BUT, generally, accumulate all-embracing concern breadth bound to six to eight keywords maximum

· Use avant-garde seek options and specialty appearance if appropriate

· For specific affair searches, accede seek engines tailored to those topics
