A _token contract_ is simply an Ethereum smart contract. "Sending tokens" actually means "calling a method on a smart contract that someone wrote and deployed".

At the end of the day, a token contract is not much more than a mapping of addresses to balances, plus some methods to add and subtract from those balances.
It is these balances that represent the _tokens_ themselves. Someone "has tokens" when their balance in the token contract is non-zero. That's it! These balances could be considered money, experience points in a game, deeds of ownership, or voting rights, and each of these tokens would be stored in different token contracts.
