Cache contains copies of data recently used by the processor and fetches several

bytes of data from memory in anticipation that the processor will access the next

sequential series of bytes.

card cage

system and storage backplanes.

be mounted in a carrier. Carriers can be inserted in modular shelves. Modular

shelves can be mounted in modular enclosures.

reader.

central processing unit (CPU)
