Mastering Operating Systems: Process Management Quiz
Test your knowledge on key concepts of operating systems, specifically focusing on process management. This quiz is designed to help you understand critical terms and principles that govern how processes operate within a uniprocessor system.
Whether you're a student or a professional, challenge yourself with questions covering:
- Concurrency
- Critical Sections
- Synchronization Mechanisms
- Processes and Threads
The management of multiple processes within a uniprocessor system is ___________.
Multiprogramming
Structured applications
Distributed processing
Multiprocessing
A situation in which a runnable process is overlooked indefinitely by the scheduler, although it is able to proceed, is ____________.
Mutual exclusion
Deadlock
Starvation
Livelock
The requirement that when one process is in a critical section that access shared resources, no other process may be in a critical section that accesses any of those shared resources is ____________.
Critical section
Livelock
Mutual exclusion
Atomic operation
A means for two processes to exchange information is with the use of ____________.
Spinlocks
Event flags
Condition variables
Messages
A semaphore that does not specify the order in which processes are removed from the queue is a _________ semaphore.
Weak
General
Strong
Binary
A ____________ occurs when multiple processes or threads read and write data items so that the final result depends on the order of execution of instructions in the multiple processes.
Atomic operation
Race condition
Livelock
Deadlock
A ___________ is an integer value used for signaling among processes.
Semaphore
Message
Mutex
Atomic operation
__________ is when the sequence of instruction is guaranteed to execute as a group, or not execute at all, having no visible effect on system state.
Critical section
[BMutual exclusion
Atomic operation
Starvation
___________ are memory words used as a synchronization mechanism.
Semaphores
Event flags
Counting semaphores
Mailboxes
The term _________ refers to a technique in which a process can do nothing until it gets permission to enter its critical section but continues to execute an instruction or set of instructions that tests the appropriate variable to gain entrance.
Spin waiting
General semaphore
Critical resource
Message passing
A _______ is a data type that is used to block a process or thread until a particular condition is true.
Deadlock
General semaphore
Condition variable
Mutex
A semaphore whose definition includes the policy that the process that has been blocked the longest is released from the queue first is called a __________ semaphore.
General
Strong
Weak
Counting
The __________ is a programming language construct that provides equivalent functionality to that of semaphores and is easier to control.
Atomic operation
Coroutine
Critical section
Monitor
Probably the most useful combination, ________ allows a process to send one or more messages to a variety of destinations as quickly as possible.
Blocking send, blocking receive
Nonblocking send, blocking receive
Nonblocking send, nonblocking receive
Blocking send, nonblocking receive
A ___________ relationship allows multiple server processes to provide concurrent service to multiple clients.
Many-to-many
Oner-to-many
Many-to-one
One-to-one
The central themes of operating system design are all concerned with the management of processes and threads.
True
False
It is possible in a single-processor system to not only interleave the execution of multiple processes but also overlap them
True
False
As an extension of the principles of modular design and structured programming, some applications can be effectively programmed as a set of concurrent processes.
True
False
Race condition is a situation in which two or more processes continuously change their states in response to changes in the other process(es) without doing any useful work.
True
False
The sharing of main memory among processes is useful to permit efficient and close interaction among processes because such sharing does not leads to many problems.
True
False
When processes cooperate by communication, the various processes participate in a common effort that links all of the processes.
True
False
Atomicity guarantees isolation from concurrent processes.
True
False
Concurrent processes do not come into conflict with each other when they are competing for the use of the same resource.
True
False
Two or more processes can cooperate by means of simple signals, such that a process can be forced to stop at a specified place until it has received a specific signal.
True
False
The fun
True
False
A process that is waiting for access to a critical section does not consume processor time.
True
False
The case of cooperation by sharing covers processes that interact with other processes without being explicitly aware of them.
True
False
It is possible for one process to lock the mutex and for another process to unlock it.
True
False
On of the most common problems faced in concurrent processing is the producer/consumer problem.
True
False
Processes need to be synchronized to enforce mutual exclusion.
True
False
