Using the Internet: Making the Most of the Web’s Resources
The Internet
The largest computer network in the world. It is a network of
networks that connects billions of computer users globally.
The concept of the Internet was developed while the US was in the
midst of the Cold Ware with the Soviet Union.
o It was created to respond to these two concerns: establishing
a secure form of military communications and creating a
means by which all computers could communicate
The modern Internet evolved from an early US government-funded
“internetworking” project called the Advanced Research Projects
Agency Network (ARPANET). It began as a four-node networking
involving UCLA, Stanford, U of C and University of Utah
o First real communication occurred in late 1969 between the
computer at Stanford and the computer at UCLA
The World Wide Web (WWW or Web) is what we use to most but is
only one component of the Internet. It is the means to access
information over the Internet (hence beginning addresses with
www)
o What distinguishes the Web from the rest of the Internet is
the use of:
Common communication protocols that tenable different
computers to talk to each other and display information
in compatible formats
Special links that enable users to navigate from one
place to another on the web
o Tim Berners-Lee, a physicist at the European Organization for
Nuclear Research, in 1989 wanted a method for linking his
research documents so that other researchers could access
them. In conjunction with Robert Cailliau, they developed the
basic architecture of the Web and created the first Web
browser (or browser), software that enables a user to display
and interact with text and other media on the Web.
