The advent of the Internet may be one of the most important technological developments in recent years . Never before have so many people had access to so many different sources of information . For all of the Internet's advantages , however , people are currently becoming aware of some of its drawbacks and are looking for creative solutions . Among the current problems , which include a general lack of reliability and numerous security concerns , the most crucial is speed .

First of all , the Internet has grown very quickly . In 1990 , only a few academics had ever heard of the Internet . In 1996 , over 50 million people used it . Every year , the number of people with access to the Internet doubles . The rapid growth has been a problem . The computer systems which run the Internet have not been able to keep up with the demand . Also , sometimes , a request for information must pass through many routing computers before the information can be obtained . A request for information made in Paris might have to go through computers in New York , Los Angeles and Tokyo in order to obtain the required information . Consequently , the service is often slow and unpredictable. Service also tends to be worse when the Internet is busiest - during the business day of the Western Hemisphere - which is also when companies need its service the most.

Some people are trying to harness the power of networked computers in such a way as to avoid this problem . In 1995 , a group of American universities banded together to form what has come to be known as Internet II . Internet II is a smaller , more specialized system intended for academic use . Since it is more specialized , fewer users are allowed access. Consequently , the time required to receive information has decreased . Businesses are beginning to explore a possible analogue to the Internet II . Many businesses are creating their own " Intranets " . These are systems that can only be used by the members of the same company . In theory , fewer users should translate into a faster system . Intranets are very useful for large national and international companies whose branches need to share information . Another benefit of an Intranet is an increased amount of security . Since only company employees have access to the information on the Intranet , their information is protected from competitors . While there is little doubt that the Internet will eventually be a fast and reliable service , industry and the academic community have taken their own steps toward making more practical global networks .
