A central processing unit ( CPU ) , also called a central processor or
main processor, is the electronic circuitry within a computer that
executes instructions that make up a computer program. The CPU
Performs basic arithmetic , logic , controlling , and input/output
( I/O ) operations specified by the instructions in the program.

Cache- A CPU cache is a hardware cache used by the central processing unit
( CPU )of a computer to reduce the average cost ( time or energy ) to access
data from the main memory . A cache is a smaller , faster memory, closer to
a processor core, which stores copies of the data from frequently used main
memory locations.
Clock rate:- Most CPUs are synchronous circuits, which means they employ
a clock signal to pace their sequential operations. The clock signal is produced
by an external oscillator circuit that generates a consistent number of pulses
each second in the form of a periodic square wave. The frequency of the clock
pulses determines the rate at which a CPU executes instructions and ,
consequently, the faster the clock, the more instructions the CPU will execute
each second.

Voltage regulator module:- Many modern CPUs have a die-integrated power
managing module which regulates on- demand voltage supply to the CPU
circuitry allowing it to keep balance between performance and power consumption.
