disk caching
Explanation:
Hi,
Magnetic hard drives use disk caching to speed up performance. This method is quite ingenious because what it does is that in a section of memory in your pc, it keeps a copy of information that was previously accessed in the hard disk. So, next time if the same data is requested, the system can refer to cache to get quick access rather than going to the hard disk (which is slower).
