Design Thinking Concept for Contiguous Memory Allocation

Design Thinking helps us understand and improve how contiguous memory allocation works by focusing on user (system) problems and practical solutions.

1. Empathize (Understand the Problem)
System users (processes) need memory quickly and efficiently. However, they face issues like external fragmentation and delays when large continuous memory is unavailable.
2. Define (Identify Core Issues)
Memory is divided into blocks, but free space becomes scattered.
Large processes cannot be allocated despite enough total memory.
Compaction increases system overhead.
3. Ideate (Generate Solutions)
Introduce paging to avoid contiguous allocation.
Use segmentation for flexible memory usage.
Improve allocation strategies (Best Fit, First Fit).
Combine methods (e.g., paging + segmentation).
4. Prototype (Model the Solution)
Create a model where memory is divided into fixed-size pages instead of continuous blocks. Simulate how processes are allocated without needing contiguous space.
5. Test (Evaluate the Solution)
Check if fragmentation is reduced.
Measure system performance and speed.
Compare with contiguous allocation.
Conclusion
Using Design Thinking, we move from a simple but inefficient contiguous allocation system to more advanced techniques like paging, improving memory utilization and overall system performance.
