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

What is the difference between write-back 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 the cache and main memory simultaneously.

What are the advantages of using write-back caching?

The main advantages of write-back caching include improved performance due to fewer writes to main memory and reduced latency.

Are there any downsides to write-back caching?

Yes, write-back caching can lead to data loss if there's a power failure before the data is written to main memory.

When should I use write-through caching instead?

Write-through caching is preferable when data integrity is critical, as it ensures that the main memory is always up-to-date.
