An integrated circuit that contains all the functions of a central processing unit of a computer.
Microprocessor
Electric current that flows in only one direction.
Direct Current
A magnet is a material or object that produces a magnetic field.
Magnet
Sends data that has been computed by the processor.
Output Units
A material in which electrons are not able to move easily
Insulator
What are the two poles of a magnet?
North and South
A smaller, faster memory, located closer to a processor core, which stores copies of the data from frequently used main memory locations.
Cache
Electric current that reverses its direction of flow in a regular pattern.
Alternating Current
Like poles of a magnet _____ each other, while unlike poles ____ each other.
Repel, Attract
A small set of data holding places that are part of the computer processor.
Registers
A closed path that electrons can flow along.
Circuit
Data is written onto hard disk by converting strings of ____________ into an electrical current fed through an electro magnet.
Bits
A digital circuit used to perform arithmetic and logic operations.
Arthmetic Logic Unit or ALU
A material in which electrons are able to move easily.
Conductor
A form of magnetism which appears in small ferromagnetic or ferrimagnetic nanoparticles.
Superparamagnetic Effect
