What is the main difference between multitasking and multiprocessing?
- Multitasking involves executing tasks sequentially, while multiprocessing involves executing tasks simultaneously (correct)
- Multitasking and multiprocessing both provide true parallel processing
- Multitasking involves executing tasks simultaneously on multiple processors
- Multitasking and multiprocessing both involve executing tasks on multiple processors
What is the primary advantage of multiprocessing over multitasking?
What is the primary advantage of multiprocessing over multitasking?
- Multiprocessing reduces the need for efficient sharing of a single processor among multiple tasks
- Multiprocessing allows tasks to be executed sequentially on a single processor
- Multiprocessing involves executing tasks independently but not simultaneously
- Multiprocessing provides true parallel processing, potentially improving overall system performance (correct)
What is the outcome of multitasking on a single processor?
What is the outcome of multitasking on a single processor?
- No difference from multiprocessing
- Execution of tasks independently on separate processors
- The illusion of parallelism with only one task actively running at any given moment (correct)
- True parallel processing with multiple tasks running simultaneously

Study Notes
Multitasking vs. Multiprocessing
- Multitasking involves executing multiple tasks simultaneously on a single processor through time-slicing.
- Multiprocessing uses multiple processors to run tasks in parallel, enabling simultaneous execution.
Advantages of Multiprocessing
- Primary advantage is true parallel processing, which enhances performance by dividing workloads across multiple CPUs.
Outcome of Multitasking on a Single Processor
- Results in the illusion of simultaneous task execution, with each task receiving a small time slice, leading to context switching.
True Parallel Processing in Multiprocessing
- Achieves true parallel processing by utilizing multiple processors, allowing tasks to run concurrently without competing for the same CPU.
Application Programs
- Designed to perform a specific task or set of tasks for the user, enhancing productivity and functionality.
Example of Application Software
- Common examples include word processors, spreadsheets, and web browsers that facilitate specific user activities.
Meaning of 'App'
- Typically refers to a software application, often used in the context of mobile devices, simplifying user interaction and tasks.
Collective noun 'Application Software'
- Refers to a group of software designed to help users perform tasks such as editing documents or analyzing data.
Coding of Applications
- Applications may be coded in various programming languages, allowing developers to create functionality tailored to user needs.
