Java Multithreading and Parallel Programming Masterclass - Parallel Versus Concurrent Versus Asynchronous Versus Non-Blo

The video tutorial covers four key concepts in parallel programming: tasks, concurrency, parallelism, and asynchronous operations. It explains the importance of understanding task dependencies and how they affect program output. The tutorial distinguishes between concurrency and parallelism, highlighting their differences and real-world applications. It also delves into asynchronous and nonblocking operations, providing examples and clarifying their significance in programming.

What is the primary factor that affects the global output of a program when tasks are executed on a single CPU core?

• The speed of the CPU

• The number of tasks

• The type of tasks

• The order of task execution

How does concurrency improve system responsiveness?

• By increasing the number of CPU cores

• By reducing the number of tasks

• By executing tasks faster

• By allowing independent tasks to run in any order

Can concurrency exist without parallelism?

• Only in theoretical scenarios

• Only with multiple CPU cores

• Yes, on a single CPU core

• No, they are always together

What is required to achieve parallelism?

• A single CPU core

• Independent tasks

• Multiple CPU cores

• Dependent tasks

What is a key characteristic of asynchronous operations?

• They execute tasks in order

• They require multiple CPU cores

• They return a promise object

• They block the current thread

How do nonblocking operations differ from asynchronous operations?

• They rely on the programmer to retrieve results

• They are faster

• They block the thread

• They require more CPU cores

What is a common example of a nonblocking operation?

• Polling an API

• Executing tasks in parallel

• Using a single CPU core

• Thread synchronization
