History of the Internet

How does the internet work?

After watching many videos on the Kahn Academy. I have learned many things about the internet. Although there were some information which I previously knew, there was many new information about the internet which I just learned about. For instance:

• Information on the internet is measured in bits
• 8 bits together make one byte
• Kilobytes = 1000 bytes, Megabytes = 1000 kilobytes, 1 Gigabyte = 1000 megabytes
• Bits are sent by electricity, light, or radiowaves
• Every internet website has an ip address 
• Every ip address is original and unique from one another
• HTTP = Hypertext Transfer Protocol
• HTML = Hypertext Markup Language 
• Encryption- the scrambling or changing of a message to hide it
• Decryption- the process of unscrambling encrypted messages 
• Caesar's Cipher- one of the first well known encryption methods
