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.
So, dogs can hear sounds that human cannot, for example: bats: they use ecolocalization yelling sounds from 14 kHz to 100 kHz, so dogs hear them better than humans do. rats: they chat at ranges from 20 kHz to 50 kHz, so ratter dogs can perfectly hear them. frogs: they chat at 35 kHz, so dogs hear them too
