välimuistiosumien
Välimuistiosuma, or cache hit in English, refers to a situation where requested data is found in a cache memory. Caches are small, fast memory components that store frequently accessed data to speed up subsequent requests. When a processor or application needs data, it first checks the cache. If the data is present in the cache, it's a cache hit, and the data can be retrieved very quickly. This significantly improves performance compared to fetching the data from slower main memory or storage.
The opposite of a cache hit is a cache miss, where the requested data is not found
