välimuistikäytännöt
Välimuistikäytännöt refers to the rules and strategies that govern how data is stored and retrieved from a cache memory. Cache memory is a small, fast type of memory used to speed up access to frequently used data. When a program requests data, the system first checks the cache. If the data is present (a cache hit), it can be retrieved very quickly. If the data is not in the cache (a cache miss), it must be fetched from the slower main memory, and then a copy is often placed in the cache for future use.
Different välimuistikäytännöt exist to optimize cache performance. A common strategy is the least recently used (LRU)
The choice of välimuistikäytäntö depends on the specific application and hardware. For instance, in web browsing,
