scientists to share information on military and

have to be connected.
– Step 1: Locate the internet service provider (ISP) or an
online service. (Internet Companies)
– Step 2: Once you find an ISP, you must install some
type of telecommunication software. This software
enables your computer to connect to another
computer.

Web browser in order to surf the Web. ( Microsoft’s
Internet Explorer or Netscape Navigator)
Browsing the Internet
• A Browser is the software program that you use
to retrieve documents from the World Wide Web
and to display them in a readable format.
• Mosaic was the Internet’s first browser, providing
a graphical interface to information on the Web.
– The browser sends a message to the Web server to
retrieve your requested Webpage.
– The browser renders the HTML code to display the
page. HTML (hypertext markup language) is the
language used to create documents for the Web.
