12 Questions
What is the purpose of an Operating System?
To manage and allocate hardware resources to different software applications
Which component of the operating system handles the management of processes and scheduling?
Kernel
What is the purpose of a Process Control Block (PCB) in an operating system?
To store the process-specific information for scheduling and resource management
What is the main purpose of using threads in concurrent programming?
To allow parallel execution of tasks within a single process
What is the significance of mutual exclusion in concurrent programming?
It ensures that only one thread can access a critical section at a time
What is the main difference between user-level threads and kernel-level threads?
User-level threads are created and managed by the kernel, whereas kernel-level threads are created and managed by user programs
What is the primary function of a Process Control Block (PCB) in an operating system?
Storing the program counter and other registers
In the context of operating systems, what is the main role of an interrupt?
To signal the occurrence of an event that needs immediate attention
Which component of the operating system is responsible for managing memory allocation for processes?
Kernel
What is the significance of context switching in a multitasking operating system?
It allows for the concurrent execution of multiple tasks on a single CPU
What distinguishes kernel-level threads from user-level threads in an operating system?
Kernel-level threads are managed by the operating system kernel, while user-level threads are managed by user applications
In concurrent programming, what effect does mutual exclusion have on shared resources?
It prevents multiple threads from accessing shared resources simultaneously to avoid inconsistency
This quiz covers the main topics, concepts, and important components of operating systems discussed in CPSC 457, particularly in Slide Set 1 and Slide Set 2. It includes information about administrative and introductory details, hardware, booting, interrupts, CPU, caches, memoization, I/O, kernel mode, user mode, interrupts vs. traps, kernel designs, and virtual machines.
