Cache Memory -

It relies on the principle of locality , storing data that the processor is likely to need next or has recently used to minimize wait times.

It is physically located directly on the CPU chip or very close to it, reducing the distance data must travel. cache memory

It is significantly faster than RAM, with access times often measured in nanoseconds. It relies on the principle of locality ,

Like RAM, it is volatile memory , meaning all stored data is lost once the computer is powered off. it is volatile memory
