Internet History & How the internet works

         Welllll, I totally missed the day on the history of the internet...so I'll Google some info on the history of the internet beginning with the  ARPANET. What I know about the  ARPANET is that it was the " eve" of internet. The very beginning of what became our Internet Explorer, Mozilla Fire Fox and what ever else internet browsers there are. It was started as a military program. The ARPANET was originally created by the IPTO under the sponsorship of DARPA and conceived and planned by Lick Licklider, Lawrence Roberts, and others. So yeah... 
        Some other random stuff I know about the history of the internet is that the TCP/IP has served us well since it was born in 1981, but for some time now it has been clear that the IP part has a limitation that makes continued growth of the Internet for decades to come problematic. In order to accommodate a large number of hosts but not waste too much space in the IP packet on overhead, the TCP/IP designers settled on an address size of 32 bits. With 32 bits, it's possible to express 4,294,967,296 different values. Over half a billion of those are unusable as addresses for various reasons, giving us a total of 3.7 billion possible addresses for hosts on the Internet. As of January 1, 2007, 2.4 billion of those were in (some kind of) use. 1.3 billion were still available and about 170 million new addresses are given out each year. So at this rate, 7.5 years from now, we'll be clean out of IP addresses; faster if the number of addresses used per year goes up. We are literally running our of IP addresses for the world. which means the internet is getting full. 

        I also learned that if under " my documents" the hit the " alt" key go under " tools" then go under " Folder options" Click it then go under the tab " view" then go under and look for the box that is checked " Hide Extensions for known file types" and un check that box. Or make sure that is un checked, and hit Apply. and exit. Create an note pad and type something like " This is a new website" and then hit " save as" and then it will have a ".txt" change the ".txt" to ".html" and hit save. Open up your web browser. And drag and drop your document on to your web page. You have created a website.
