In this chapter

  • Figuring out where the Internet came from

  • Understanding the FTP protocol

  • Working with Internet email addresses and protocols

  • How HTTP and HTML make the Web work

Now that you are pretty well rooted in LAN technology and have had a chance to peruse some information on TCP/IP networking and WAN connectivity, it’s time to take a look at the biggest network in the world—the Internet. In Chapter 12, “TCP/IP Network Administration,” we took a look at IP addressing, DHCP, IP routing, and more importantly the Domain Name Service (DNS). Understanding how the TCP/IP protocol stack works and how services like DHCP and DNS work provides you with insight into how data moves on the Internet and how individual users connect to the Internet.
