What is the difference between write-back caching and write-through caching?

What is the difference between write-back caching and write-through caching?

Write-back caching stores data in the cache and writes it to the main memory later, while write-through caching writes data to both simultaneously.

What are the advantages of using write-back caching?

Write-back caching can improve performance by reducing the number of write operations to the main memory, which can be slower.

Are there any downsides to write-back caching?

Yes, if the system crashes before the data is written back to memory, it can lead to data loss.

When should I use write-through caching instead?

Use write-through caching when data integrity is critical, as it ensures that data is always written to memory immediately.
