Välimuistitoiminnot
Välimuistitoiminnot, often referred to as caching, is a technique used in computing to store frequently accessed data in a temporary location, known as a cache. This temporary storage is typically faster to access than the original data source, which can significantly improve the performance and responsiveness of a system. When data is requested, the system first checks the cache. If the data is found there, it is called a cache hit, and the data can be retrieved quickly. If the data is not in the cache, it is called a cache miss, and the system must retrieve it from its original, slower source. After retrieval, this data may then be added to the cache for future use.
Caches can be implemented at various levels within a computer system. For example, CPU caches store frequently
