, Computer Organization and
Architecture
• Computer Architecture is a blueprint for design and
implementation of a computer system.
• It refers to the overall design of a computer system, including
the hardware and software components that make up the
system and how they interact with each other.
• Computer architecture provides the functional details and
behavior of a computer system.
• Computer Architecture mainly deals with the functional
behavior of a computer system and covers the "What to do?"
part.
• In the designing process of a computer system, the computer
architecture is to be defined before the computer
organization.

, Computer Organization and
Architecture
• Computer Organization refers to the way in which the
hardware components of a computer system are arranged
and interconnected.
• It implements the provided computer architecture and covers
the "How to do?" part.
• Computer Organization is to be defined after the decision of
the computer architecture.
• It just provides information that how operational attributes of
a computer system are linked together and help in realizing
the architectural specification of the computer.
• It involves the design of the interconnections between the
various hardware components, as well as the design of the
memory and I/O systems. 3
