What is the main difference between 'write-through' and 'write-back' caching strategies?
- Write-through and write-back are terms used interchangeably.
- Write-through and write-back caching strategies are essentially the same.
- Write-through involves writing data to both the cache and the underlying storage immediately, while write-back involves writing to the cache first and updating the underlying storage at a later time.
- Write-through involves writing data to the cache only, while write-back involves writing data to both the cache and the underlying storage simultaneously.
The main difference is that 'write-through' immediately updates both the cache and the underlying storage, while 'write-back' involves updating the cache first and delaying the update to the underlying storage.
