Internet Protocol Mr. Paulk

What is a Protocol ? A protocol is a set of rules that govern how systems communicate. For networking they govern how data is transferred from one system to another.

WHAT IS Internet protocol? The Internet Protocol (IP) is the method or protocol by which data is sent from one computer to another on the Internet. Each computer (known as a host) on the Internet has at least one IP address that uniquely identifies it from all other computers on the Internet. 

Ip address? An IP address is a 32- bit number that identifies each sender or receiver of information that is sent Basically it Identifies you! It’s like your home address but for internet!

Putting it all together Think of the protocol like a sandwich or a cake!

Task! Lets try and put it in your own words… Directions: Take the next 10-15 minutes and think of your own “protocol”. Draw it out on a piece of paper like the sandwich example from the video. Make sure you label the application (The start) -> Transport-> Networking -> Datalink (The End)

How it all works… NETWORK FOURTH THIRD INTERNET SECOND TRANSPORT FIRST APPLICATION FOURTH NETWORK

HTTP HTTPS FTP NETWORKING TERMS MEANING IP TERM Encryption Internet Protocol -a digital media transport system that runs over standard IP networks HTTP Hypertext Transfer Protocol (HTTP) - the standard protocol for transferring hypertext documents “information” on the World Wide Web.
