BLANK Law predicts that the number of transistors in a CPU will double about every two years.

moore’s

The CPU is located on the

motherboard

A CPU’s processing power is determined by the combination of the clock speed, the number of cores, and the amount of BLANK
memory.

CACHE

The BLANK of a CPU dictates how many instructions the CPU can process each second.

clock speed

The CPU is composed of two units, the control unit and the
.

arithmetic logic unit

The process the CPU performs for each program instruction is called the
.

machine cycle

BLANK is a feature of a CPU that allows it to begin to fetch the next instruction before it has finished executing the current one.

Hyperthreading

Running the CPU at a faster speed than the manufacturer recommends is called BLANK

overclocking

BLANK is the type of RAM memory used most often in today’s lower-end computers.

DDR

The CPU’s BLANK
memory is a form of RAM that gets data to the CPU for processing much faster than bringing the data in from the computer’s RAM.

cache

RAM is an example of BLANK
storage because when the power is turned off, RAM is cleared out.

volatile

The time it takes a storage device to locate stored data and make it available for processing is called BLANK
time.

A(n) BLANK
moves over the spinning platters to retrieve data from a hard disk.

read/write head

A stoppage of the hard drive that often results in data loss is called a(n)
