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
It is typically organized into levels (L1, L2, L3), where L1 is the fastest and smallest, while L3 is larger and slightly slower but still much faster than main memory. Cache Memory in Computer Organization - GeeksforGeeks cache memory
It is significantly faster than RAM, with access times often measured in nanoseconds. A primary feature of is its extremely high
It is physically located directly on the CPU chip or very close to it, reducing the distance data must travel. It is physically located directly on the CPU
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.
