Threads and Processes Quiz

What is the key difference between a process and a thread?

• A process is a lightweight unit of execution, whereas a thread is a separate program.

• A process has its own memory space, while threads within a process share memory space.

• Threads are isolated, while processes share resources.

• Threads consume more system resources than processes.

Why are threads faster than processes?

• Threads run on a higher priority than processes.

• Threads do not require context switching.

• Threads share resources, reducing overhead.

• Threads use separate memory spaces, making execution quicker.

Which of the following is an example of a multithreaded application?

• A basic text editor that processes one file at a time.

• A web browser handling multiple open tabs independently.

• A calculator performing a single computation.

• A static website with no dynamic content.

How do threads improve CPU and memory utilization?

• By allowing multiple applications to run simultaneously.

• By reducing the number of running processes.

• By sharing resources within a process and enabling parallel execution.

• By limiting the number of processes that can run at a time.

What is an example of a multithreaded program in Windows 11?

• Microsoft Notepad

• Microsoft Edge handling multiple downloads

• A single-task script running in PowerShell

• A command-line program that executes one operation at a time

What is the main difference between user threads and kernel threads?

• User threads are managed by the operating system, while kernel threads are managed by applications.

• User threads run independently of processes, while kernel threads rely on processes.

• User threads are managed by user-level libraries, while kernel threads are managed by the OS.

• Kernel threads are created by the user, while user threads are created by the OS.

Which of the following is an example of a kernel thread?

• A Python script using the threading module.

• A background process running in a web browser.

• A Windows 11 system thread handling file operations.

• A script using JavaScript’s event loop.

Which threading model maps multiple user threads to a single kernel thread?

• One-to-One

• Many-to-One

• Many-to-Many

• Single-Threaded

Why is the One-to-One threading model commonly used in modern operating systems?

• It reduces the overhead of managing multiple threads.

• It improves performance by allowing each user thread to have a dedicated kernel thread.

• It prevents context switching between multiple threads.

• It eliminates the need for thread scheduling.

Which threading model is most suitable for high-performance computing?

• Many-to-One

• One-to-One

• Many-to-Many

• Single-Threaded
