1. • Processor

2. Definition of
Processor
• Known as the
Central
Processing Unit
(CPU)
• A processor or ‘microprocessor’ is a microchip implanted
in CPU’s hard drive that processes instruction sent to it by
the computer and software

3. Function
• Interprets and carries out the basic instructions that operate the
computer
• Used to direct the operation of all other hardware devices and
execute application instruction. Processors carry out these
functions by processing digital information, receiving data and
providing data

6. • A control unit is circuitry that directs operations within
the computer's processor by directing the input and
output of a computer system. The processor then
controls how the rest of the computer operates (giving
directions to the other parts and systems).
• A control unit works by gathering input through a
series of commands it receives from instructions in a
running programs and then outputs those commands
into control signals that the computer and other
hardware attached to the computer carry out.

7. Short for Arithmetic Logic Unit, ALU is one of the
many components within a computer processor. The
ALU performs mathematical, logical, and decision
operations in a computer and is the final processing
performed by the processor. After the information
has been processed by the ALU, it is sent to the
computer memory.

8. • Components of
processor that direct
and coordinates most of
the operation in the
computer
• It interprets issued by
program and the initiate
the appropriate action to
carry out the instruction.

Arithmetic Logic
Unit
• Performs arithmetic,
comparisons, and
logical operations.
• Arithmetic operations
include additions,
subtractions,
multiplication, and
division.
• Logic operation involve
comparing data either
more than, less than or
equal.

Cycle
Fetching
Process of obtaining
program instruction or
data item from memory
Decoding
Process of translating
the instructions into
the signals the
computer can execute.
Executing
Process of carrying out
of commands. Performs
the request instruction
such as adding two
number or deciding
which one of the is
larger
Storing
Store the result to an
internal register ( a
temporary storage
location or to memory)
