Concurrent Processing Quiz

What is the primary assumption made in this video about the viewer's knowledge?

• They know how to code in multiple languages.

• They understand basic programming concepts.

• They have a solid understanding of concurrent thinking.

• They are familiar with operating systems.

Which of the following best describes reactive programming?

• A technique to optimize memory usage.

• A way to interact with applications while other tasks run in the background.

• A method to execute tasks sequentially.

• A strategy to enhance security in applications.

How do web browsers utilize the concept of availability of services?

• By prioritizing video content over text.

• By serving parts of a webpage, like text and images, before video content.

• By delaying all tasks until the user is ready.

• By loading all content at once.

What is parallelism in the context of concurrent processing?

• A method to reduce memory usage.

• Running independent tasks simultaneously on multiple processors.

• Executing tasks one after another.

• A way to enhance user interface responsiveness.

What is one of the main reasons for using concurrent processing?

• To increase the number of tasks completed in a given time.

• To reduce the complexity of programming.

• To ensure tasks are executed in a specific order.

• To minimize the use of multiple processors.

What is a potential safety issue with concurrent processing?

• Tasks may execute too quickly.

• It can only be used in single-core systems.

• Concurrent tasks might corrupt the program's consistent state.

• It always requires more memory.

What does the concept of liveness in concurrent processing refer to?

• Ensuring tasks do not wait indefinitely for each other.

• Increasing the number of processors used.

• Maximizing the speed of task execution.

• Reducing the number of tasks in a system.

Why can threads be considered expensive in concurrent processing?

• They require less memory.

• They involve overheads like scheduling and context switching.

• They do not support multi-core systems.

• They are always slower than sequential processes.

What is a deadlock in the context of concurrent processing?

• A method to optimize task execution.

• A state where tasks wait indefinitely for each other.

• A situation where tasks execute too quickly.

• A strategy to enhance user interface design.
