5. External Cache
If the computer cannot find what it needs in
the Internal Cache, it looks in the external
cache. This is usually located on the
Motherboard. In some CPU chips the
External cache is built in.
Internal Cache
When the computer needs data it first
looks in the Internal cache. This is
located on the CPU chip and provides
the fastest way for the computer to get
data.
