Computer organization is an organization in which we organize all hardwares into a system where as architecture is explain about the functions of hardware devices

A computer's architecture is its abstract model and is the programmer's view in terms of instructions, addressing modes and registers. A computer's organization expresses the realization of the architecture. Architecture describes what the computer does and organization describes how it does it.

Architecture and organization are independent; you can change the organization of a computer without changing its architecture. For example, a 64-bit architecture can be internally organized as a true 64-bit machine or as a 16-bit machine that uses four cycles to handle 64-bit values.

The difference between architecture and organization is best illustrated by a non-computer example. Is the gear lever in a car part of its architecture or organization? The architecture of a car is simple; it transports you from A to B. The gear lever belongs to the car's organization because it implements the function of a car but is not part of that function (a car does not intrinsically need a gear lever).

1.The architecture indicates its hardware whereas the organization reveals its performance.
2.for designing a computer, its architecture is fixed first and then its organization is decided.

computer organization is concerned with the way the hardware components operate and the way they are connected together to form computer system while comp architecture is concerned with the structure and behavior of comp system as seen by the user. It includes information ,formats,instruction set and techniques for addressing memory

It deals with design aspects of computer that assembly programmer needs to know like instruction set(i.e. instructions supported), instruction format (i.e. how instruction will be specified), addressing modes, data types supported etc.

Architecture are those attributes visible to the programmer.
Organization is how features are implemented.
Control signals, interfaces, memory technology

Computer architecture is user visible containing instruction set, bytes required to store the input, I/o mechanisms and techniques of addressing mode.

Computer organization includes operational units and their interconnections.

Ex: Computer architecture decides whether there should be a multiply instruction and computer organization decides how to calculate it.

Computer Organization: This is implementation of Computer Architecture. It dear with operational feature of computer that how hardware are working by Computer Architecture and helps to programmer understand working model of hardware and enable them coding for accessing different method hardware and interrupt, control signal etc.

Computer Architecture: Deals with operational activity in different parts of hardware. Basically description of processor,buses, Memory etc, ISA of the processor. Data is representing in bits. Assembly language programming is closest to computer architecture.

Example: Designing an algorithm is computer architecture and coding is computer organization.

The architecture refers to the qualification/characteristics/attributes/specialty of any object (object may be a computer) which is desired from any component.
whereas Organization refers to that how the different components are interconnected together in order to make our object workable/usable. (Workable machine may be a computer or car or robot or biological objects may be human being).

Computer Architecture: Those attributes which are visible to programmer.
Computer Organization: Those attributes which refer to the components and its interconnection which realize the architecture.

Computer Architecture is just like the architecture of a building of an institution and the organization is how each and every component (like rooms, ladders, elevators, lavatories, corridor etc.) are managed to realize the functionality of the building, so that the institution as a whole depends on the functionalities of the components. Yes it is possible that Organization can be changed keeping the architecture intact, just imagine if the institution has sold the building and another new set up is installed by another institution with completely different work domain.

Computer architecture refers to those attributes of a system visible to a programmer or put another way those attribute that have a direct impact on the logical execution of a program. Eg Instruction set the number of bits used to represent various data types, I/o mechanism. On the other hand computer organisation refers to the operational units and their inter-connection that realize the architectural specifications eg., control signals and memory technology used.
