Question

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

Answer 1

Answer:

Explanation:

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

recording density is 1200 bpi

= 1200 bits per inch

= 1200*12  bits per feet

= 14400 bits per feet

Tape is 4000 feet long

Storage capacity = 4000 * 14400 = 57600000 bits = 56250 kb

1 kb = 1024 bits

if we consider in question

recording density is 1200 Bpi

= 1200 bytes per inch

= 1200*12  bytes per feet

= 14400 bytes per feet

Tape is 4000 feet long

Storage capacity = 4000 * 14400 = 57600000 kb = 56250 kB

1 kB = 1024 bytes
