From there the processing results can be transferred to
an output device. The fourth storage section, the
PROGRAM STORAGE AREA, contains the program
statements transferred from an input device to process
the data. Please note that the four areas (input, working

These results are transferred from the output storage

output devices, separate from the CPU itself, are called
peripheral equipment. The CPU communicates with
