Question

A tape is 4000 feet long and has a
recording density of 1200 bpi. What is
its storage capacity

Answer 1

Answer:

Storage capacity is  the product of length and the data recording density.  Data recording density is measured in bytes per inch.According to the question,

Storage capacity= Length * data recording density

                              = 4000* 1200

                               = 4800000 bytes

                            As in decimal one Kb is equal to 1000 bytes

therefore, the storage capacity is 4800 Kb.
