The document discusses the typical components of a CPU, including the arithmetic logic unit (ALU) which performs arithmetic and logical operations, the floating point unit (FPU) which handles decimal operations, and the control unit (CU) which controls and coordinates the other components by decoding and executing instructions. It also mentions registers for temporary data storage and cache memory for faster access to instructions. The document concludes by defining quantum computing as a technology that applies quantum physics principles to use qubits as simultaneous processors and memory.

3. Arithmetic/ Logic Unit (ALU)

There is electronic circuitry in arithmetic logic unit
which executes all arithmetic and logical operations.
Its function is obvious from its name. It performs
arithmetic calculations like as addition, subtraction,
multiplication and division as well as comparisons.
The unit can compare numbers, letters, or special
characters. There can be more than one Arithmetic
logic unit in a CPU.

4. Arithmetic/ Logic Unit (ALU)
and Floating Point Unit (FPU)
 (ALU) 
 The Part of CPU core
that performs logical
operations and integer
arithmetic problems.
 (FPU) 
 The Part of CPU core
that performs decimal
arithmetic problems.

5. Control Unit (CU)
 There is circuitry in the control unit which uses
electrical signals to instruct the whole computer
system for carrying out or executing, already stored
program instructions. Its name clearly shows that it
controls and co-ordinates computer components. It
extracts instructions from memory and decodes and
executes them. In fact it regulates the flow of
information through the processor. In short, it can be
said ,this component receives, decodes, stores
results and manages execution of data that flows
through the CPU.

6. Control Unit (CU)
 The Part of a CPU core that coordinates its
operations.

8. Registers & Cache Memory

Registers are temporary storage areas which
are responsible for holding the data that is to
be processed. They store the instructions and
data in a processor also physical addresses.
This data is further used by Control Unit.
 Internal Cache Memory is used to store
instruction as handheld rather than storing on
RAM. There are Levels in Cache Memory to
Store instructions.

10. Quantum Computing
 A technology that applies the principles of Quantum
Physics and Quantum Mechanics to computers to
direct atoms or nuclei to work together as Quantum
bits (qubits), which functions simultaneously as the
computer’s processor and memory.
