Computer Architecture and Operating Systems

1. Explain the operation and basic parts of the processor and the computer.
2. Explain how to fetch, decode and execute instructions in the processor.
3. Explain the basic algorithms in assembler.
4. Explain the reasons for the division of the operating system on the layers and subsystems.
5. Explain the operation of basic operating system components (subsystems).
6. Apply actions for operating system maintainance.
