Q. Explain about disk caching scheme?
The disk caching scheme can be used to speed up performance of disk drive system. A set (cache) of buffers is assigned to hold some disk blocks that have been recently accessed. In effect the cached blocks are in memory copies of disk blocks. If data in a cache buffer memory is modified only local copy is updated at that time. Therefore processing of data occurs using cached data avoiding need to frequently access disk itself.
