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.
Humans can hear frequencies from about 20 hertz to 20 kilohertz, dogs from about 20 hertz to 40 kilohertz, and cats from about 30 hertz to 60 kilohertz. âCats are capable of hearing the very high pitch of high-frequency sounds â it would appear three times as high and ones that humans canât detect.umans can hear frequencies from about 20 hertz to 20 kilohertz, dogs from about 20 hertz to 40 kilohertz, and cats from about 30 hertz to 60 kilohertz. âCats are capable of hearing the very high pitch of high-frequency sounds â it would appear three times as high and ones that humans canât detect.
