What is the Internet?
We know that one or more computers connected
together are called a network. The Internet is
tens of thousands of networks connected together
to share information. The computers connect to
host servers so that anyone may access the
information on the web pages. The Internet was
started by the United States Department of
Defense in 1969 so the workers could share and
communicate information around the world. Today
more than 100 million people are using the
Internet.
