Dod/ARPA/NSF/TCP/IP/DNS/ftp/CERN

This article gave us another lil history and background of the Web starting off with the start of the internet thanks to DoD and ARPAnet, then lead us into TCP/IP (Internet Protoc-well everybody read it so I guess I don't need to explain it..back to what I was saying..) addresses and how they work. Which is basically a giant naming system of numbers, 32-bit numbers, that work with the different nodes of the internet to connect all of the different local networks to the actual Internet (a physical connection). Keep in mind, these numbers all must be unique..and before I even reached the next point in the paragraph I questioned whether or not we were running out of these IP numbers (yeah, I know, silly question), and sure enough, next paragraph it explained how in 1998, a new IP standard, IP6 was introduced..now the numbers can be up to 128-bit.

The article then gets into domain names, which is something I feel like I knew, but reading this, like, made so much more sense. So there are two to three or more domain names, all the domain names relate to the host, the domain that the host is a part of, and the type of organization that the host resides in. (You know, like .edu, .com. .gov...and so on and so forth.) Following the description of domain names, the article explains how important the DNS is, that's used to generate and convert domain names so that what we are sending over the internet can be transmitted over the internet.

Then to quickly wrap it up, the article introduces telnet, ftp and mailto, which basically were like the first protocols that allowed for the transmittal of messages, documents, and information over the internet. But because users had to know way to much about these protocols in order to use them good ol' Tim Bernes-Lee helped give birth to the Web, in 1991 (one year after I was born, wow, I'm older than the web!).

Oh, and I can't forget the second reading...which was a bunch of sizes and numbers of the web, Web Metrics...to be honest, I didn't fully read through every line of this reading, I more over skimmed through the numbers to gain an idea of some of these fine details of the web.
