What is the difference between Multitasking and Multiprocessing Operating Systems?
This question distinguishes between executing multiple tasks and running multiple processes simultaneously. It tests fundamental OS architecture knowledge.
Why Interviewers Ask This
Understanding the distinction helps interviewers assess your foundational knowledge of how modern computers manage workloads. While often used interchangeably, they refer to different implementation levels regarding CPU usage and hardware utilization. This is crucial for optimizing backend services on Flipkart's infrastructure.
How to Answer This Question
Define multitasking as rapid context switching on a single core. Define multiprocessing as true parallel execution on multiple cores. Highlight the role of the kernel in managing both. Mention how modern OSs combine both approaches for efficiency.
Key Points to Cover
- Single vs multiple CPU cores
- Context switching definition
- Parallelism vs concurrency
- Kernel management roles
Sample Answer
Multitasking involves a single CPU rapidly switching between tasks to create the illusion of simultaneous execution. Multiprocessing, however, uses multiple processors or cores to execute actual parallel tasks. Modern op…
Common Mistakes to Avoid
- Treating them as identical
- Ignoring hardware requirements
- Not mentioning context switching
