What is write-back caching?

Can you explain what write-back caching is?

Sure! Write-back caching is a caching technique where data is written to the cache first and then to the main storage later.

What are the advantages of using write-back caching?

The main advantages include improved performance, as it reduces the number of write operations to the main storage, and it can also enhance data integrity.

Are there any downsides to write-back caching?

Yes, one downside is the risk of data loss if the system crashes before the data is written back to the main storage.

How does it differ from write-through caching?

In write-through caching, data is written to both the cache and the main storage simultaneously, ensuring data consistency but potentially reducing performance.
