Power supply

converts AC power from the wall outlet into the lower voltages of DC power required to power all components of the computer

AC/DC current

Direct current only flows in one direction. It is therefore a straight line above the zero line.

Alternating current changes direction meaning that the electrons flow in one direction and then the other direction. It changes direction every half cycle resulting in a sine graph like trace on the oscilloscope.

Bus

Connections between components, etched connections on circuit board; Expansion Bus- connects CPU to other components
