Qubits Related to RAM?
This coincidence just shows that the function $n \mapsto 2^n$ shows up in many places. For example, an $n$ bit register can store up to $2^n$ different values. If wireless frequency is parametrized using $n$ bits, then there are up to $2^n$ possible frequencies (in fact, there are probably a bit less). If an IP address is $n$ bits, then there are at most $2^n$ possible IP addresses (in fact, there are fewer). If a cryptographic key is $n$ bits long, then there are $2^n$ possible keys. And so on.
