18 Questions
In a Symmetric Multiprocessing (SMP) system, what is a key characteristic of the processors?
They are similar and have comparable capabilities
What is a benefit of multicore CPUs compared to multiple chips with single cores?
More efficient and consume less power
Which of the following levels of control does an integrated operating system provide in a Symmetric Multiprocessor?
Job, task, file, and data element levels
What type of design does the Intel Core i7-5960X use?
Quad-core design
Which of the following is true about processors in a Symmetric Multiprocessing (SMP) system?
They share main memory and can perform the same functions
What does a stand-alone computer system with Symmetric Multiprocessing (SMP) consist of?
Similar processors with comparable capabilities sharing main memory
What is the main advantage of using a priority scheme for interrupt handling?
Allows for handling interrupts based on their importance
In the context of interrupt handling, what does 'nested interrupts' refer to?
One interrupt occurring during the handling of another interrupt
Which type of interrupt is generated by an I/O controller to signal errors or successful completion?
I/O Generated
What is the key disadvantage of disabling interrupts during interrupt processing?
Interrupts remain pending until processor enables them
How does a priority scheme impact the order of interrupt handling?
Prioritizes higher-priority interrupts over lower-priority ones
Why is it important to consider priority levels when dealing with multiple interrupts?
To manage which interrupts are handled first based on importance
Which of the following statements best describes the trade-off in the storage device hierarchy?
Decreasing cost per bit, increasing capacity, and decreasing access time
What is the primary purpose of caching in a computer system?
To improve the performance of the system by temporarily storing frequently accessed data in faster storage
Which of the following I/O techniques allows the processor to continue executing other instructions while the I/O operation is being performed?
Direct memory access (DMA)
What is the main advantage of using a cache in a computer system?
Improved performance by reducing the average access time to frequently used data
Which of the following statements is true about the relationship between cache and main memory?
Cache is used to temporarily store copies of data from main memory
What is the primary purpose of the different levels of the storage device hierarchy?
To improve the performance of the system by providing different levels of speed and cost trade-offs
Test your knowledge on Symmetric Multiprocessing (SMP) in Operating Systems, focusing on the characteristics of stand-alone computer systems with multiple similar processors sharing main memory and I/O devices. Learn about processor scheduling, task allocation, and internal connection schemes.
