Differences between Computer Architecture and Computer Organization
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.
Architecture describes what the computer does.
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.
Organization describes how it does it.
Difference between Computer Architecture and Computer Organization:
|S.NO||Computer Architecture||Computer Organization|
|1.||Architecture describes what the computer does.||The Organization describes how it does it.|
|2.||Computer Architecture deals with the functional behavior of computer systems.||Computer Organization deals with a structural relationship.|
|3.||In the above figure, it’s clear that it deals with high-level design issues.||In the above figure, it’s also clear that it deals with low-level design issues.|
|4.||Architecture indicates its hardware.||Where Organization indicates its performance.|
|5.||For designing a computer, its architecture is fixed first.||For designing a computer, an organization is decided after its architecture.|
|6.||Computer Architecture is also called instruction set architecture.||Computer Organization is frequently called microarchitecture.|
|7.||Computer Architecture comprises logical functions such as instruction sets, registers, data types, and addressing modes.||Computer Organization consists of physical units like circuit designs, peripherals, and adders.|
|8.||Architecture coordinates between the hardware and software of the system.||Computer Organization handles the segments of the network in a system.|
