Background
History
Definition of Net
The Internet is the publicly accessible
worldwide system of interconnected
computer networks that transmit data
by packet switching using a
standardized Internet Protocol (IP).
It is made up of thousands of smaller
commercial, academic, domestic and
government networks. It carries
various information and services, such
as electronic mail, online chat, and the
interlinked web pages and other
documents of the World Wide Web.
WWW domination
How big is the web?
• 56 billion static web pages are publiclyavailable on the World Wide Web.
• Another estimated 6 billion static pages are
available within private intranet sites
• 200+ billion database-driven pages are
available as dynamic database reports ("invisible
web" pages)
• Google.com indexes 9.75 billion web pages.
Deep Web
• The invisible web,, a vast repository of
information that search engines don't have
access to, such as databases
• Private networks, called intranets, that are not
actually hooked up to the Web
• Forms, like ColdFusion or CGI
• Password-protected sites, like a university
library
• Sites that intentionally, for various reasons,
keep their information from being indexed by
search engine spiders
