1. Difference between computer architecture and computer organization:
| Computer architecture | Computer organization |
| It includes emphasis on logical design, computer design and the system design | It includes emphasis on the system components, circuit design, logical design, structure of instructions, computer arithmetic, processor control, assembly language, programming methods and of performance enhancement |
| It is concerned with structure and behaviour of computer as seen by the user | Computer organization is concerned with the way the hardware components operate and the way they are connected together to form the computer system |
2. Explain the significance of layered architecture
Significance of layered architecture: In layered architecture, complex problems can be segmented into smaller and more manageable form. Each layer is specialized for specific functioning. Team development is possible because of logical segmentation. A team of programmers will build. The system and work has to be sub-divided of along clear boundaries.
3. Explain the various types of performance metrics.
Performance metrics include availability, response time, Channel capacity, latency, Completion time.
