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.
Like RAM, it is volatile memory , meaning all stored data is lost once the computer is powered off.
It is significantly faster than RAM, with access times often measured in nanoseconds.
It is physically located directly on the CPU chip or very close to it, reducing the distance data must travel.
A primary feature of is its extremely high speed , which allows it to act as a high-speed buffer between the CPU and the main memory (RAM). Key Characteristics
