3. Cache L3

Cache L3 or Degree 3 cache is the kind of cache reminiscence which is positioned removed from the processor and has a decrease entry velocity than cache L1 and L2. Typecache, which is also referred to as predominant reminiscence, is answerable for storing information that’s not often accessed by theprocessor.

4. Cache Laborious Drive
