How the Internet Works
                          
A few things that I remember learning from the videos that stood out to me were how many megabytes there are in a single song. There are also millions of IP addresses and there's a whole process to how IP addresses are made, and that people can steal them and hack into the websites with the URL's. I also saw how the data we receive is delivered from our phones to computers and other devices. I saw how people keep their websites secure, so how to prevent viruses because hackers can take over millions of computers worldwide.
