Caching

According to the article, HashCache, Vivek Pai, a computer scientist at Princeton University has a new method for storing Web content because in some countries, users can only afford low-bandwidth connection or an equivalent fraction of dial-up connection. This method is called HashCache, a better way to cut the cost (less expensive). According to the article, “hashcache is a high efficient method of caching-storing frequently accessed Web content on a logical hard drive instead of using precious bandwidth to retrieve the same information repeatedly”. This caching technology requires a large hard disk and a lot of RAM (random access memory) to store all data content. Other caching systems uses hash function. According to Pai’s technology, “he uses novel hash function: the number that the function produces defines the spot on the disk where the corresponding Web object can be found”. HashCache is still being tested because it is an early stage of development.
