How does the BC wallet work? What is stored in there?

[wingding]

Is it only the transactions that is stored? Or is there a particular number/code that has the value of a given amount of BTC?
I read about the so called 'brain wallet'. It means you memorize your money as sequence of number. But is that possible? What do you memorize?

And yes - I already read 'how does it work' at bitcoin.org, but still dont get it.

when ever you get xfererd or spend BTC it goes on block chain. YOu can always check what was spend/xfered/how many transactions by clicking on your "receive" address and google it. It will show everything that has been spent/received/transacations from that address

A wallet is generally a term for your personal collection of incoming payment addresses. The actual data stored in Bitcoin's wallet.dat also includes an address book of people you can pay and the names you've assigned to your addresses, and a separate record of just your transactions which speeds up the calculation of your balance.
