WWW is one application that runs on the internet, and allows us to access data via web servers Email, ftp (file transfer protocol), usenet (news groups, now largely replaced by forums) are the other aspect URL: protocol://machinename.domain_name IP Address: 4 numbers between 0-255 each. How many IP addresses possible? 255*255*255*255 = 4.22 billion We are running out of them. Estimated time: 2011. Need to switch to IPV6, has 2 X 10^128 addresses.
