Cache whose contents are duplicated in another cache level.

Additional cache level present in some architectures.

Larger processor cache often shared by multiple cores.

Processor cache generally larger and slower than L1.

Small, very fast processor cache close to execution units.

Very small cache level found in some processor architectures.

Fixed-size unit of data transferred between cache levels.
