The operating temperature is the range of ambient temperature within which a power supply, or any other electrical equipment, operate in. This ranges from a minimum operating temperature, to a peak or maximum operating temperature, outside which, the power supply may fail.

The memory capacity is the amount of data a device can store at any given time in its memory.

A serial interface is a communication interface between two digital systems that transmits data as a series of voltage pulses down a wire. Essentially, the serial interface encodes the bits of a binary number by their "temporal" location on a wire rather than their "spatial" location within a set of wires.
