Threads in C# Quiz

What is a thread in C#?

• A thread is the smallest unit of execution within a process.

• A thread is a form of input in C#

• A thread is a type of data structure in C#

• A thread is a method for error handling in C#

How do you create a thread in C#?

• By using the Task class from the System.Threading namespace

• By using the Thread class from the System.Threading namespace

• By using the Process class from the System.Threading namespace

• By using the Timer class from the System.Threading namespace

Explain the process of starting a thread in C#.

• Create a new Thread object and pass the method to be executed as a parameter to the ThreadStart delegate. Then call the Start method on the Thread object to begin execution.

• Pass the method to be executed as a parameter to the ThreadRun delegate

• Call the Execute method on the Thread object

• Use the Run method to start the thread

What is synchronization in the context of threads in C#?

• Stopping all threads from accessing shared resources

• Coordination of multiple threads to ensure they do not interfere with each other while accessing shared resources

• Running multiple threads simultaneously without any coordination

• Allowing threads to interfere with each other while accessing shared resources

What are locks in C# and how are they used for synchronization?

• Locks in C# are used to ensure that only one thread can access a resource at a time, thus providing synchronization.

• Locks in C# are not necessary as the language automatically handles synchronization between threads.

• Locks in C# are used to speed up the execution of multiple threads accessing a resource simultaneously.

• Locks in C# are only used for debugging purposes and do not affect synchronization.

Explain the concept of thread safety in C#.

• Thread safety is not important in C# as the language automatically handles concurrent access to shared data.

• Thread safety ensures that shared data is accessed in a manner that prevents concurrent access from causing inconsistencies or corruption.

• Thread safety means allowing multiple threads to access shared data simultaneously without any issues.

• Thread safety only applies to single-threaded applications and has no relevance in multi-threaded environments.

What are the potential issues that can arise when working with multiple threads in C#?

• Memory leaks, buffer overflows, and stack corruption

• Infinite loops, syntax errors, and logic errors

• File not found errors, permission denied errors, and network connection errors

• Race conditions, deadlocks, and thread synchronization problems

How can you handle exceptions in a multi-threaded application in C#?

• By using try-catch blocks within each thread

• By terminating the entire application when an exception occurs

• By using if-else statements to handle exceptions

• By ignoring the exceptions and letting the threads continue running

Choose the correct statement about process-based multitasking.

• a) A feature that allows our computer to run two or more programs concurrently

• b) A program that acts as a small unit of code that can be dispatched by the scheduler

• c) Only A program that acts as a small unit of code that can be dispatched by the scheduler

• d) Both A feature that allows our computer to run two or more programs concurrently & A program that acts as a small unit of code that can be dispatched by the scheduler

Choose the statements which indicate the differences between the thread based multitasking and process based multitasking.

• a) Process-based multitasking handles the concurrent execution of programs

• b) Process-based multitasking handles the concurrent execution of pieces of the same program

• c) Thread-based multitasking handles the concurrent execution of programs

• d) Thread-based multitasking deals with the concurrent execution of pieces of the same program
