Information Retrieval System
Information
can be sent from any computer to any others 24 hours a day. There are various types
of resources available for information retrieval.
One
major resource is web sites or home pages of organization or individuals like www.bbc.co.uk. Another resource that can be
used for information retrieval is search engines. www.google.com is a very popular search
engine. You can also find books and reports and repositories of S/W
applications and so much more.
Who pay for it?
Who
pay for the internet? Do you have to pay for the internet access?
There
are no owners for the internet. However, these networks should be developed and
maintained by the providers (ISP/IAP). Therefore those who provide network connectivity
(internet service providers) have to change individuals/organizations when they
want access the internet through their networks.
Generally,
there are two type of fees one for access time and the other one for internet connectivity.
Access
time is usually based on local telephone charges (e.g. Dial up connection) or a
fixed amount irrespective of access time (e.g. ADSL Connection).
In
some countries, internet connection can be obtained through cable TV network.
At
the same time, an individual or organization can obtain a dedicated direct
connection to the internet (e.g. Leased line) if they wont to have very high
speed connection and the charges for such connection usually high.
