It just occurred to me that there are two very different kinds of caches which aren't really distinguished by terms:

- Cache, as in processor cache: total access mediation, i.e. all operations go through the cache. Cache bypass might be possible but rare in practice.

- Cache, as in application cache (e.g. redis/memcached/@lru_cache): thing were you put some result to recall later conditionally. Exactly the opposite of total access mediation: application needs to explicitly use cache.

The first one I'd call Zwischenspeicher. The second I'd call Ergebnisabrufspeicher.
