Chapter 7 : Role of Multithreading in Multitasking Flashcards
What is process?
- Any program in execution
What is multitasking ?
- Refers to the ability of an operating system to manage the execution of multiple tasks simultaneously
What are the types of multitasking?
- Preemptive Multitasking
- Cooperative Multitasking
What is Preemptive Multitasking?
- The operating system decides when to switch between tasks
What is Cooperative Multitasking?
- Each task decides when to give up control of the CPU
What is Multithreading?
- Concurrent execution of multiple threads within a single process
What is a threads in Multithreading?
- Each threads perform a specific task independently while sharing the process’s resource
List out 3 points Multithreading enhances Multitasking
- Efficiency
- Responsiveness
- Parallelism
- No multithread , no multitasking
How does multithreading improves the efficiency?
- Allowing multiple tasks to run concurrently within a single process, reducing the need for context switching
Why does multithreading improves responsiveness?
- Making it easier to handle user inputs, background tasks, and processing simultaneously
Why does multithreading provide parallelism?
- Enables better use of CPU resources by allowing threads to be distributed across multiple
List out 3 the Advantages of Multithreading in Multitasking
- Reduced Overhead
- Resource Sharing
- Improved Application Performance
How does Multithreading reduce overhead?
- Threads shara the same memory space, reducing the overhead associated with interprocess communication and context switching
Why resource sharing in Multithreading is an advantages?
- Easier resource sharing among threads within the same process compared to separate processes
How does Multithreading improve the application performance?
- More efficient use of CPU time, especially in I/O - bound and computationally intensive task
List out the 3 disadvantages of Multithreading in Multitasking
- Compatibility Issues
- Difficulty in ensuring different systems work together
- Network Integration
- Connecting different network for seamless communication, data security concerns
- Human Factors
- Resistance to change, need for ongoing training and support
List out 2 challenges of multithreading in multitasking
- Complexity in Synchronization
- Debugging Difficulties
How to prevent complexity in synchronization?
- Ensuring that threads don’t interfere with each other when accessing shared resources
How to prevent debugging difficulties?
- Multithreaded applications can be harder to debug due to potential issues like race conditions, deadlocks, and non-deterministic behevior
