Write-Through Cache

A write-through cache is a memory management technique used in computer systems that ensures data is written to both the cache (a fast storage area) and the main memory simultaneously. This means that whenever information is updated, it is instantly saved in both locations. This approach ensures data consistency, so if the system crashes, the data in the main memory is always up-to-date. However, it can be slower since writing to two places takes more time than just writing to the cache. Overall, it provides a balance between speed and reliability in data storage.
