Logical Representation Vs Physical System
- A computer system can be represented in either a logical or physical form.
- Both useful are in understanding computer system theory.
Physical
- The actual hardware as seen in the real life
- Contains micro-electrons & physical mechanisms
- Power by electricity
- Very detailed & complex
- Difficult to fully understand without a working knowledge of electronics
Logical
- A basic model of computer system
- The model is built from a number of different blocks
- Each block performs a different task
- All blocks work together to process data into information
- Model is conceptual
