Chapter 13: Concurrency Flashcards
A process is a group of associated threads that execute in the same shared environment.
If false, why?
True.
A thread is the smallest unit of execution that can be scheduled by the operating system. If false, why?
True.
A single-threaded process contains exactly one thread, whereas a multi-threaded process supports more than one thread.
If false, why?
True.
A single process has shared memory between its threads.
If false, why?
True.
A task is a single unit of work performed by a thread.
If false, why?
True.
The property of executing multiple threads and processes at the same time is referred to as concurrency.
If false, why?
True.
Operating systems use a thread scheduler to determine which threads should be currently executing.
If false, why?
True
Local variables are shared among all threads within a process.
If false, why?
Local variables are stored on the stack and are thread-specific.
(False)
Static methods and variables are unique to each thread within a process.
If false, why?
Static methods and variables are shared among all threads in the same process.
(False)
A context switch occurs when a thread completes execution and terminates.
If false, why?
A context switch happens when a thread’s execution is paused to allow another thread to run.
(False)
A thread scheduler guarantees an equal amount of CPU time for every thread.
If false, why?
The scheduler may use different strategies, and priorities can affect execution time.
(False)
A thread cannot interrupt another thread, even if it has a higher priority.
If false, why?
A higher-priority thread can supersede a lower-priority thread in scheduling.
(False)
CPUs are directly connected to the OS thread scheduler.
If false, why?
The OS thread scheduler manages threads, but CPUs execute instructions independently.
(False)
A thread can execute multiple tasks at the same time.
If false, why?
A thread can only execute one task at a time but can switch between tasks.
(False)
