1. hertz (hertz):

Hertz is the basic unit of computer operation speed, indicating the number of cycles per second. 1 Hz is equal to 1 operation per second. For example, 1GHz stands for a period of one billion times per second.

2. kilohertz:

Kilohertz represents a period of 1000 times per second. In early computers, the speed of the processor is usually between tens of KHz and hundreds of KHz.

3. Megahertz (MHz):

Megahertz means one million cycles per second. In modern computers, the speed of the processor is usually between several hundred MHz and several thousand MHz.

4.GHz (gigahertz):

Gerhertz stands for a period of one billion times per second. This is a common speed unit of modern computer processors, especially the processors of personal computers (PCs) and servers are usually in GHz.

5.TFLOPS (megabit per second floating-point operation):

TFLOPS refers to the number of floating-point operations that can be performed per second, and it is an important indicator to measure the high-performance computing power of a computer. One TFLOPS equals one trillion floating-point operations per second.

6.PFLOPS (floating point operations per second):

PFLOPS refers to one trillion floating-point operations that can be performed every second. This level of performance is usually used in supercomputers and scientific research fields.

7. Everest (Hz):

EFLOPS refers to one billion floating-point operations that can be performed every second. This level of performance is usually used for top supercomputers to deal with complex scientific and engineering problems.

8.ZFLOPS (GHz):

ZFLOPS means that you can perform 100 trillion floating-point operations per second. This level of computing power is usually only used for very large-scale scientific computing projects.
