What do you mean by Computer Architecture and Computer Organization?
Computer architecture and computer organization are related but distinct concepts in
the field of computer science.
Computer Architecture is a functional description of requirements and design
implementation for the various parts of a computer. It deals with the functional
behavior of computer systems. It comes before the computer organization while
designing a computer.
Computer architecture refers to the design of the internal workings of a
computer system, including the CPU, memory, and other hardware components.
It involves decisions about the organization of the hardware, such as the
instruction set architecture, the data path design, and the control unit design.
Computer architecture is concerned with optimizing the performance of a
computer system and ensuring that it can execute instructions quickly and
efficiently.
Computer Organization refers to the operational units and their interconnections that
implement the architecture specification. It deals with how the components of a
computer system are arranged and how they interact to perform the required
operations.
Computer Organization comes after the decision of Computer Architecture first.
Computer Organization is how operational attributes are linked together and
contribute to realizing the architectural specification. Computer Organization
deals with a structural relationship.
The organization describes how it does it.
Computer organization is concerned with the physical implementation of the
architecture design and includes decisions about the interconnection and
, communication between components, such as the bus structure, memory
hierarchy, and input/output systems.
In summary, computer architecture is focused on the design of the internal workings
of a computer system, while computer organization is focused on the implementation
of that design. Computer architecture is concerned with the high-
level design decisions, while computer organization deals with the low-level
implementation details.
