ROLE OF
CACHE
MEMORY
SUPERMARKET, SARI-SARI STORE, AND CONSUMER
ANALOGY
The memory stores the data and the microprocessor processes it. But getting the
data from the memory takes long time. That is why cache predicts the data that
the microprocessor needs and store it, making the data transfer a bit faster. On
the images above, the products from the supermarket, represents the data, the
customers is the microprocessor and the sari-sari store is the cache while
supermarket is the memory. The products that the customer needed might be or
might not be available on the sari-sari store. If the sari-sari store has the certain
product, then the customer doesn't need to go to supermarket anymore and can
easily access the product. Making the whole process of purchasing a lot faster.
