Kilobytes Megabytes Gigabytes. The size of information in the computer is measured in kilobytes, megabytes, gigabytes, and terabytes. In this section, we'll look at common sizes you would see in real life, and work some arithmetic. Any thinking person today should have a rough idea of what KB, MB and GB are.
The maximum upper range of human hearing is about 20 kHz for children, declining to 15-17 kHz for middle-age adults. The top end of a dog's hearing range is about 45 kHz, while a cat's is 64 kHz.
They can hear higher-pitched sounds than either dogs or humans, detecting frequencies from 55 Hz up to 79 kHz (a range of 10.5 octaves) and dogs hear from 67 Hz to 44 kHz, which are both ranges of about 9 octaves.
