Computer architecture and organization are two important concepts in computing. Architecture refers to the overall design of the computer, while organization refers to the way components are arranged to achieve the architecture. In other words, computer architecture defines the logical design of the machine, while computer organization provides the physical implementation of that design. Both concepts are important in understanding how computers work.
Computer architecture is the fundamental design of a computer system. It covers the circuitry and design of the system. Computer organization is the way in which the system’s components are put together and how they work together.
What is Computer Organization and Architecture?
Computer Organization and Architecture is the study of internal working, structuring, and implementation of a computer system. Architecture in the computer system, same as anywhere else, refers to the externally visual attributes of the system.
Computer architecture is the overall design of a computer system, while computer organisation is the way in which the architecture is implemented.
What is the difference between computer architecture and Computer Organization Quora
Computer organization mainly deals with how a particular hardware works in a computer. For example, how the ALU, CPU, and memory work together to perform tasks. Computer architecture, on the other hand, deals with how to design a circuit for such hardware. For example, how to design an ALU that can perform addition and subtraction, or how to design a CPU that can execute a set of instructions.
Computer organisation is a field which explains about structure and behaviour of digital computers. Its main objective is to make us understand the over all computer hardware structure and all its peripheral devices. It tells us how all the units in the system are arranged and interconnected to each other.
What is the example of computer architecture?
These are just a few examples of computer architectures. Each has its own strengths and weaknesses, so it’s important to choose the right one for your needs.
Computer architecture is the study of how computer components are connected together to form a computer system. Computer organization is the study of the structure and behaviour of a computer system as seen by the user. It acts as the interface between hardware and software.
What is the importance of computer architecture and organization?
The computer architecture is the blueprint for a family of computers. It defines the logical interface that programming languages and compilers target, and determines the mix of functional units the system is composed of and how they are interconnected.
Operating systems are responsible for managing all of the hardware and software resources of a computer. They provide a platform for application software to be executed. The architecture of an operating system defines how these components interact with each other.
What are the two types of computer architecture
CISC and RISC are two major approaches to processor architecture. CISC is a design philosophy that favors a large number of complex instructions over a smaller number of simple instructions. RISC, on the other hand, favors a smaller number of simple instructions over a larger number of complex instructions. There is no clear winner between the two approaches, as each has its own advantages and disadvantages.
There are various types of registers in a typical CPU architecture. Each type of register has a specific role to play in the functioning of the CPU.
The accumulator (AC) is a special register that is used for storing the intermediate results of arithmetic and logic operations.
The data registers (DR) are used for storing data that is to be processed by the CPU.
The address registers (AR) are used for storing the address of data in memory.
The program counter (PC) is a special register that stores the address of the next instruction to be executed by the CPU.
The memory data registers (MDR) are used for storing data that is to be read from or written to memory.
The index registers (IR) are used for storing the address of data in memory, with the help of which the CPU can access data at different locations in memory.
The memory buffer registers (MBR) are used for temporary storage of data that is to be read from or written to memory.
What are the basic concepts of computer organization?
There are three types of registers in computers:
1. The control register controls the operations of the computer.
2. The status register shows the current status of the computer.
3. The instruction register stores the present instruction being executed by the computer.
The computer organization is the study of the structure and behaviour of digital computers. The main objective of this subject is to understand the overall basic computer hardware structure, including the peripheral devices. In addition, this subject also covers the principles of operating systems, computer networks and security.
What are the four types of computer architecture
A computer architecture refers to the functionality and design of a computer system. There are four main types of computer architectures: Von-Neumann, Harvard, Instruction Set, and Microarchitecture.
Von-Neumann architecture is the standard architecture for computers. It is named after mathematician and physicist John von Neumann who first proposed it. This architecture uses a stored program concept where instructions and data are stored in the same memory.
Harvard architecture is a variation of the Von-Neumann architecture. It is named after Harvard University where it was first developed. In this architecture, data and instructions are stored in separate memory units. This allows for faster fetching of instructions as they are not blocked by data.
Instruction Set Architecture (ISA) is a type of computer architecture that provides a consistent interface between software and hardware. ISA defines all the operations that a computer can perform as well as the bit sizes and formats of data that can be processed.
Microarchitecture is the lowest level of computer architecture. It refers to the design of the individual components of a processor, such as the control unit, arithmetic logic unit, and registers.
System design is the process of designing a complete computer system, including both hardware
A computer system consists of three components: Central Processing Unit, Input devices and Output devices. Input devices provide data input to processor, which processes data and generates useful information that is displayed to the user through output devices. This is stored in computer’s memory.
What is the most common computer architecture?
Most modern computers use a Von Neumann architecture, with one memory space for both instructions (software) and data. In some systems, devices may be accessed through a separate address range (designated for I/O ports), which acts like memory-mapped I/O but has a distinct addressing scheme.
Operating system is a basic thing and it is necessary for accessing the computer hardware. It is the interface between user and computer hardware.
Conclusion
The main difference between computer architecture and computer organization is that computer architecture focuses on the overall design of the computer system, while computer organization focuses on the internal workings of the system.
Computer architecture refers to the design of a computer’s hardware, while computer organization pertains to the design of the software that controls the operation of the hardware.
