Search Engines Search engines allow repparttar user to enter keywords relating to a topic and retrieve information about Internet sites containing those keywords. Many search engines compile a database spanning multiple Internet protocols, including HTTP, FTP, and Usenet. They may also search multimedia or other file types on what is known as repparttar 118489 “deep Web.” Some of repparttar 118490 most popular search engines are Google, MSN, Ask Jeeves and Alta Vista.

Technically, a search engine service consists of three parts, a spider, index and search engine mechanism. The spider is a program that combs repparttar 118491 Web from link to link, identifying and reading pages. The index is a database containing a copy of each Web page gathered by repparttar 118492 spider. And repparttar 118493 search engine mechanism is software that enables users to query repparttar 118494 index.

Here’s how search engines work: With most search engines, you fill out a form with your search terms and then ask that repparttar 118495 search proceed. The engine explores its index and generates a page with links to those resources containing some or all of your terms. These resources are usually presented in ranked order according to term relevancy.

Check for Accuracy and Reliability Since repparttar 118496 Internet is a self-publishing medium, anyone with repparttar 118497 necessary technical skills can place information on repparttar 118498 Web. Therefore, it’s important to evaluate repparttar 118499 accuracy and reliability of your research information. You should consider: •Who published repparttar 118500 information - A site maintained by a university or government organization is probably more reliable than one maintained by a private individual.

•The age of repparttar 118503 material - If you need current statistics, carefully check repparttar 118504 age of repparttar 118505 material you’ve found. A site dealing with historical information may not need updating as frequently as one related to news and current events.

•Why repparttar 118506 material exists - Many special interest groups have Web pages. And while this doesn't necessarily mean repparttar 118507 material is biased, it’s something you should consider. Think about whether they might have some reason, other than pure helpfulness, for posting information.

For repparttar 118508 most successful Internet research, try to cross-check repparttar 118509 information you find as much as possible.

One of repparttar

most important features relating to Internet trading field is e-commerce. Although e-commerce is poise to become one of repparttar 118488

key forums of future trade within this decade, unfortunately, Pakistan is way behind most of repparttar 118489

countries of repparttar 118490

region in Internet connections essential for conducting this mode of business. According to research 4.5 persons per 10,000 people in Pakistan use this facility compared with 45 in India (the ratio had increased over repparttar 118491

past few years). It was found that Singapore tops in repparttar 118492

use of Internet facility in Asia-Pacific where 2435 persons per 10,000 people avail this facility. The highest percent of people using Internet was in US where 4501 persons per 10,000 have access to Internet. A study of Internet use in Pakistan revealed that repparttar 118493

usage is mostly at individual level in main cities where families use this mode to maintain regular contacts with their relatives living abroad in repparttar 118494

west. It was found that, there was a limited use of Internet in repparttar 118495

country for e-commerce; this facility is availed mostly by repparttar 118496

big corporations and repparttar 118497

already established exporters, who with their limited knowledge of computer use this facility mostly to maintain quick contacts with their regular customer abroad. It basically requires a web-site builder, which host personalized, advertising free web-sites in a variety of layouts that supports customize logos and on-line chat capabilities. It is also noted that there were only 100 web-sites a decade ago, which have now grown to over 10 million. Pakistan’s share in these web-sites is negligible. Most of repparttar 118498

web-sites operating in Pakistan are not updated. The nation loses its credibility when most of its web-sites are out dated and provide stale information. Acquiring computers is not enough. It is regrettable that most of repparttar 118499

business concerns use computers as a typewriter and data bank. The computers in these offices are not even linked through a common server. Internet is considered as a luxury instead of necessity. This attitude has to be changed for accepting repparttar 118500

challenges of globalization. An Internet service provider said, repparttar 118501

per hour cost charged by repparttar 118502

ISP in Pakistan is not very high as it is declared by many entrepreneurs. It said repparttar 118503

cost looks higher when repparttar 118504

user indulge in surfing unwanted sites… while targeted surfing would not only bring huge benefits to repparttar 118505

users but also cut repparttar 118506

internet charges.
