P2L2 - part 1

What are the two components of a single-threaded process?

• Address space and execution context

• Code and data

• Heap and CPU registers

• Stack and virtual memory

What is the benefit of multithreading in terms of program execution?

• Threads can work in parallel on different components of the program's workload

• Threads can share the same address space

• Threads can specialize in different tasks

• Threads can store more information in the processor cache

Why is a multithreaded application more likely to fit in memory compared to a multiprocess application?

• Multithreaded applications require only one address space

• Multithreaded applications have smaller memory requirements

• Multithreaded applications have faster disk swaps

• Multithreaded applications have better inter process communication

What is the purpose of mutual exclusion in multithreading?

• To allow threads to operate on data in an exclusive manner

• To synchronize the execution of multiple threads

• To prevent data races and inconsistencies

• To improve the performance of multithreaded applications

What is a mutex?

• A lock that provides exclusive access to a shared resource

• A mechanism for inter thread communication

• A construct used to create threads

• A data structure representing a thread

What is the critical section in multithreading?

• The portion of code protected by a mutex

• The section of code where threads are created

• The section of code where threads are joined

• The section of code where threads are blocked

How can a mutex be unlocked?

• By reaching the end of a clause following a lock statement

• By explicitly calling an unlock function

• By releasing the mutex owner

• By unblocking all the threads

What is the purpose of thread creation?

• To represent a thread with its own execution context

• To create a new address space for each process

• To synchronize multiple threads

• To allocate memory for a multithreaded application

What is the purpose of the join mechanism in multithreading?

• To block the parent thread until the child thread finishes processing

• To allocate resources for the child thread

• To communicate the status of the child thread to the parent thread

• To deallocate resources associated with the child thread

What is an example of a synchronization mechanism in multithreading?

• Mutex

• Condition variable

• Thread ID

• Program counter
