18 Questions
What type of memory is main memory usually implemented in?
Dynamic random-access memory (DRAM)
Why is it not possible for programs and data to permanently reside in main memory?
Main memory is too small to store all needed programs and data permanently.
What is the main requirement for secondary storage in computer systems?
To hold large quantities of data permanently
What does ROM stand for in computer systems?
Read Only Memory
Which technology is commonly used for implementing main memory in computers?
DRAM
Why do most computer systems provide secondary storage as an extension of main memory?
Because secondary storage can hold large quantities of data permanently
What is the responsibility of the operating system in connection with process management?
Creating and deleting both user and system processes
Which activity is NOT part of memory management carried out by the operating system?
Optimizing cache hit ratio
What is the main function of the main memory in a computer system?
Storing program instructions and data that the CPU can access directly
Which responsibility falls under memory management performed by the operating system?
Deciding which parts of memory are currently being used by the user
What is the role of the operating system in process communication?
Providing mechanisms for process synchronization
In a computer system, what is the purpose of keeping several programs in memory?
To improve CPU utilization and speed of response to users
What is the purpose of cache coherency in a multiprocessor environment?
To ensure that a copy of data exists in multiple caches simultaneously
What is the sequence of copying an integer A from a magnetic disk to the processing program?
Magnetic disk -> Main memory -> Cache -> Internal register
In a multiprocessor environment, why is maintaining cache coherency important?
To prevent data inconsistency among different caches
What is one of the purposes of an operating system according to the text?
To hide hardware specific details from users
Why are copies of data in a multiprocessor environment found in multiple caches?
To speed up data access by having duplicate copies
In the context of storage systems, what does hiding hardware peculiarities from users mean?
Shielding users from having to deal with low-level hardware details
