What is memory?
It is the computer's physical workspace that stores the instructions, programs and data needed to accomplish the tasks executed by the processor for some interval of time, even after electrical power to the computer is turned off.

What is an oscilloscope?
Oscilloscopes are test instruments that display electronic signals (either waves or pulses) on a screen. It creates its own time base against which signals can be measured, and displayed frames can be frozen for visual inspection. It is sometimes abbreviated as CRO, for cathode-ray oscilloscope, or commonly called scope or O-scope.
