All this means that every computer has a specific number that only that computer has. No two computers share the same number. (There is a technical way to get around that, but I am not going to bog down in that kind of techie stuff here!)
A router uses the identity numbers (IP-addresses) to figure out the shortest route from here to there.
If the Internet keeps growing at the present alarming rate then there will be a problem soon with the IP-addresses running out. (there are only just so many combinations of 0-255 in 4 fields). The techies are hard at work fixing that problem - do not ask me how...
