Questions:
1. How does the clock speed of a processor affect the number of instructions carried out?
2. Explain the relationship between bandwidth and the amount of information processed in one instruction.
3. Why is cache memory important for a processor?
4. What is the difference between a job scheduler and a process scheduler?
5. Describe the five different states a process can be in and what each state signifies.
6. What information does a process control block contain, and why is it important?
7. How does the concept of a linked list of PCBs help in managing processes efficiently?
Correct answers:
1. The quicker the clock speed, the more cycles are run, leading to more instructions being carried out.
2. The efficiency of a processor's architecture determines the actual amount of work the processor can perform.
3. Bandwidth determines how much information can be processed in one instruction, with wider bandwidth allowing for more data to be processed.
4. Cache memory on a processor allows for faster access to data compared to RAM, improving overall performance.
5. A job scheduler manages multiple processes within a job, while a process scheduler handles the execution of individual processes.
6. The five states a process can be in are hold, ready, run, wait, and finish, each representing a different stage in the process lifecycle.
7. An IO request page fault puts a job in a waiting state until the necessary resource is available for it to continue processing.
8. A process control block contains essential information about a job, including its current status, resource usage, and progress.
9. Process control blocks are used to organize processes by storing them in queues based on their status and resource needs.
10. Using a linked list of PCBs helps in efficiently managing processes by allowing for easy access and manipulation of process information.
