This question already has an answer here:

I'm trying to understand the technical details of Ethereum and one thing I can't find any info about is the data to be sent to a contract.

For example, I have a very simple coin flip betting contract on the testnet ethereum chain, and when I execute the "Bet and flip" function on the contract I get (in Mist) a prompt with this "data" that will be sent to the contract:

0x25d8dcf2

What exactly is the format of this data, and how do I make sense of what each byte means?
