Exam 2: Hardware and Software

Because of the electromechanical processes involved in using primary storage,it is considerably slower than secondary storage.

Each central processing unit (CPU)produces a series of electronic pulses at a predetermined rate,called the ______,which affects machine cycle time.

_____ is a storage technology for less frequently needed data so that it appears to be stored entirely on tape cartridges,although some parts may be stored on faster hard disks.

The _____ is the part of the central processing unit (CPU)that sequentially accesses program instructions,decodes them,and coordinates the flow of data in and out of the arithmetic/logic unit (ALU).

RAM stands for random access memory,a form of memory that holds its contents even if the current is turned off or disrupted.
