<human>:  How do 32-bit and 64-bit computing differ?
<bot>: 32-bit computing is a system where each variable is limited to a maximum of 32 bits. 64-bit computing is a system where each variable is limited to a maximum of 64 bits. This means that a 64-bit computer can store more data than a 32-bit computer. This is important for applications that require large amounts of data, such as video games and scientific simulations.
