____ are used only by the currently executing program.

The conductivity of ____________________ varies in response to the electrical inputs applied.

Low voltage circuits are less susceptible to damage from voltage surges and static electricity.

The control unit cannot execute instructions without assistance from the ALU.

A(n) ____ directs the CPU to route electrical signals representing data inputs through predefined processing circuits that implement the appropriate function.

A(n) ____________________ is a command to the CPU to perform a primitive processing function on specific data inputs.

In an electrical computer, ____________________ is performed by forcing electricity to flow through millions of electrical switches and wires.

In most CPUs, the ____ is the time required to fetch and execute the simplest instruction in the instruction set.

The term ____ describes instructions executed after the guess but before the final result is known with certainty.

Electronic ____________________ control electrical current flow in a circuit and are implemented as transistors.

The ____________________ of most materials increases as their temperature increases.

​The ____ section of the CPU performs all computation and comparison operations.

A ____ instruction copies data bits to storage locations and can copy data between any combination of registers and primary storage locations.

A ____ is a unit of data containing a fixed number of bytes or bits and can be loosely defined as the amount of data a CPU processes at one time.

Arithmetic SHIFT instructions are more complex when applied to twos complement values because the rightmost bit is a sign bit.

____ is a philosophy of processor design that deliberately includes complex instructions.

A CPU is a complex system of interconnected electrical switches.

____ states that the cost of fabrication facilities for the latest chip generation doubles every four years.

A(n) ____________________ SHIFT instruction performs multiplication or division.
