Ethereum Virtual Machine questions by five year old

[metalbean]

Hi guys,

Can someone explain to "a five year old" why EVM can be 256bit when Java Virtual Machine is only 32 bit. How can EVM  "calculate" or "compute" so much faster than other virtual machines?

There is a JIT interpreter in EVM, is it to convert from bytecode to machine code? How does contract ABI code and creation code fall into the puzzle?

Thanks!
