The Chinese name for computer hz is Hertz, hz is the basic unit of frequency; computer hz is the speed of computer running. The larger the number before hz, the faster the computer runs. On the contrary, the number before HZ The smaller the value, the slower the computer runs.

What does computer hz mean?

Hz, the Chinese name is Hertz, abbreviated as: Hertz, which is the basic unit of frequency. It commemorates the German physicist Heinrich who verified the existence of electromagnetic waves. Named after Heinrich Rudolf Hertz.

HZ is the standard unit of measurement for frequency: Hertz. The system clock in a computer is a typical pulse signal generator with a fairly accurate and stable frequency. HZ on the computer is Hertz, which is the unit of frequency and how fast the computer runs. The larger the number before HZ, the faster the computer runs; conversely, the smaller the number before HZ, the slower the computer runs. Therefore, the higher the HZ, the faster the computer.

Extended information:

Hz is the unit of frequency. Frequency refers to the number of times that electrical pulses, alternating current waveforms, electromagnetic waves, sound waves and mechanical vibration cycles are repeated in one second.

1Hz means one vibration per second, 60Hz means 60 vibrations per second.

Hz is a very small unit, usually preceded by k (thousands), M (millions), G (billions), T (trillions) and other orders of magnitude units.

KHz, kilohertz, is the frequency, which can also be said to be the sampling rate. It is generally 44.1KHz, because this is the standard for music CDs.

KHZ Kilohertz: Kilohertz, the abbreviation is kHZ or KHZ, which is the unit of alternating current (AC) or electromagnetic wave (EM) frequency, equal to 1000 Hertz (1000Hz). This unit is also used in the measurement and description of signal bandwidth.

AC signals with a frequency of 1kHZ are within the range of human hearing. If a signal of this frequency is applied to headphones or speakers, the tone that comes out will have a slope, and it will drop to the so-called "audio midrange". The wavelength of an EM signal with a frequency of 1kHz is 300 kilometers, which is approximately 190 miles. Standard amplitude modulation (AM) broadcast bandwidth is in the range of 535kHz to 1605kHz. Some EM transmissions are in the millions of kHz.
