Physical medium can store bits or qubits {information science} {information theory, mathematics}. Physical media can transform, to input, process, or output information.
memory
Because information uses bits, two-states devices, such as on-off switches, can store information. Devices like switch series can store bit series. More switches can hold more bits.
memory: address
Switches have addresses, so processing can access them and use relations between them.
information
Information amount is alternative number.
transfer
On or off signal series can transmit information-bit series. Signals have sequence numbers, so processing can access them and use relations between them.
transfer: capacity
Carrier-wave frequency has number of on-off positions per second, which is information carrying capacity.
cross-section
Information channels have cross-sections, which can hold waves or carriers, with total channel capacity. Surface area limits information capacity. Information transfer always flows through surface, even from three-dimensional space region.
