Ques 9. Answer : cache memoy
Cache memory is a special type of RAM which is very vary fast as compared to the normal RAM or main memory. It is used to improve the performance of computer. What actually happens is that the CPU first checks the cache of the data is present in it, then it uses the data and since the cache memory is very fast, the process is completed in very less time. If the data is not found in cache, then CPU looks in the main memory.
