2.1.5a Problem tackling

What does concurrency mean in the context of an application?

• An application is making progress on a single task.

• An application is making progress on more than one task at the same time.

• An application is paused while waiting for resources.

• An application is running in a single-threaded environment.

Which of the following is an example of a task that cannot be done concurrently in house construction?

• Laying the foundations for multiple houses.

• Ordering materials for later stages.

• Constructing the roof before the walls.

• Painting the walls after they are built.

What is the skill involved in thinking concurrently?

• Identifying tasks that can be done sequentially.

• Working out which parts of a program can be processed at the same time.

• Focusing on a single task until completion.

• Avoiding multitasking at all costs.

In the analogy of constructing a new housing estate, what is a task that can be done concurrently?

• Constructing the roof before the walls.

• Laying the foundations for multiple houses at once.

• Building the walls before laying the foundations.

• Installing windows before the walls are built.

Why is it important to determine which parts of a program are dependent on others?

• To ensure all tasks are done concurrently.

• To avoid unnecessary delays and ensure efficient progress.

• To focus on a single task at a time.

• To increase the complexity of the program.

Which of the following is NOT a benefit of thinking concurrently?

• Improved efficiency in task completion.

• Reduced waiting time for dependent tasks.

• Increased complexity in task management.

• Better resource utilisation.

What is a real-life example of a task that can be done concurrently with laying foundations in construction?

• Constructing the roof.

• Ordering materials for later stages.

• Painting the interior walls.

• Installing electrical wiring.

Which of the following is a key aspect of concurrency in programming?

• Ensuring all tasks are completed in a linear sequence.

• Identifying independent tasks that can be executed simultaneously.

• Avoiding the use of multiple threads.

• Focusing on a single task to avoid errors.

What is the main challenge when thinking concurrently in programming?

• Ensuring tasks are done one after the other.

• Identifying tasks that are dependent on each other.

• Avoiding the use of any concurrency.

• Ensuring all tasks are completed by a single processor.

In the context of the video, what is the purpose of using an analogy like constructing a housing estate?

• To confuse the audience with unrelated examples.

• To provide a clear and relatable example of concurrency.

• To demonstrate the complexity of programming.

• To show the importance of construction work.
