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.
Compared to humans, dogs and cats have a much different range of hearing. Humans can hear sounds in the 64 Hz (low sounds) to 23 kHz (high sounds) range. By comparison, a cat has a range of about 45 Hz to 64 kHz and a dog has a range of about 67 Hz to 45 KHz.
