Internet vs. World
Wide Web
Before we can talk about the Web, you must first understand something about how it all ties together
through the "Internet" (inter-network).
The Internet can be likened to a gigantic international electronic plumbing system.
One or more computers are joined together into a group called a "Network", like
parents and children joined as a family. The Internet is a group of computer
groups speaking to each other or, a network of networks that link computers
to computers by sharing information. Information is transferred through common
protocols two of which are TCP/IP.
Each computer runs software to give information (serve) and/or to view information.
The Internet is the channel through which this takes place. This information
that is served or viewed is stored in files or documents on individual computers
around the world. Computers on the Internet use the following services:
1 Email (electronic mail)
2 FTP (file transfer protocol to send/receive complex files)
3 WWW (world wide web – via browsers and the HTML language)
4 Telnet (permits your computer to log into another computer)
5 Gopher (an early text method for viewing documents)
The WWW is a service on the Internet that allows
you to view, show or act on information stored on individual computers. When
you use a browser to view web pages (like Internet Explorer) you are viewing
documents on the World Wide Web. The World Wide Web functions through
a programming language called HTML. The HTML and other programming embedded
within a page creates web links that allows you to do things on the web
such as search, view, communicate or buy and sell products and services.
It is the grouping of the individual web links, text and images that make up
your e-commerce system.
Where do all these links, text and images live? The answer to that is the Web Site, which is our next
section in this ecommerce tutorial.
