TCP\IP, WHICH IS THE TRANSMISSION CONTROL PROTOCOL\INTERNET PROTOCOL. IT IS THE BASIC CONTROL SYSTEM, OF THE INTERNET AND IT IS REALLY ONE OR TWO SYSTEMS, IN THE COMPUTER WORLD PROTOCOL IS THE STANDARD WAY OF DOING THINGS-AN TRIED AND TRUSTED METHOD THAT EVERYONE FOLLOWS TO SEE THINGS HAPPEN PROPERLY.
INTERNET PROTOCOL (IP) IS SIMPLY THE ADDRESS SYSTEM OF THE INTERNET.

ALL MACHINES ON THE INTERNET- YOURS, MINE, AND EVERYONE ELSE'S-ARE IDENTIFIED BY THE INTERNET PROTOCOL(IP) ADDRESS, WHICH TAKES THE FORM OF A SERIES OF DIGITS SEPARATED BY DOTS OR COLUMNS.
IF ALL MACHINES HAVE NUMERIC ADDRESSES, EACH MACHINE KNOWS EXACTLY HOW EACH OTHER MACHINE INTERACTS.
WHEN IT COMES TO WEBSITES, WE USUALLY REFER TO THEM BY EASILY IDENTIFIABLE NAMES INSTEAD OF THEIR ORIGINAL IP ADDRESSES - AND THERE IS A RELATIVELY SIMPLE SYSTEM CALLED DNS (DOMAIN NAME SYSTEM) THAT STARTS THE COMPUTER. TO SEE THE IP ADDRESSES FOR ANY WEBSITE.
