1. Hz:

Hertz is the most basic unit to measure the speed of computer operation, indicating how many periodic operations can be performed per second. For example, 1 Hz means that 1 operation can be performed per second. In computers, hertz is usually used to indicate the clock frequency of CPU, that is, how many clock cycles the CPU can execute per second.

2. gigahertz (GHz):

Gigahertz is 1000 times that of Hertz, which means that one billion operations can be performed every second. In the computer field, especially the clock frequency of the processor, it is often in GHz. For example, 1GHz is equal to 10 9 clock cycles per second.

3. FLOPS per second:

FLOPS is a unit to measure the speed of computer floating-point operation, indicating how many floating-point operations can be performed per second. Floating-point operations are usually used to deal with complex mathematical operations, such as scientific calculation and image processing. The performance of supercomputers and high-performance computers is usually measured by FLOPS.

4. Millions of instructions per second (MIPS):

MIPS is a unit to measure the execution speed of computer instructions, indicating how many instructions can be executed per second. The higher the MIPS value, the faster the instruction execution speed of the computer. MIPS is usually used to measure the processor performance of a computer, which reflects the instruction-level parallelism of the computer.

5. Gigabit floating-point operations per second (GFLOPS):

GFLOPS are gigabit floating-point operations per second, which means that one billion floating-point operations can be performed per second. GFLOPS are usually used to describe the performance of high-performance computers, supercomputers, etc. Dealing with large-scale scientific and engineering calculations.

6. Billion floating-point operations per second (TFLOPS):

TFLOPS is 1000 billion floating-point operations per second, which means that trillions of floating-point operations can be performed per second. TFLOPS is usually used to describe the performance of high-performance computer clusters, supercomputers and other fields in dealing with complex scientific calculations, climate simulation, astrophysics and so on.

7. Bits per second (bps):

Bit per second is a unit to measure the speed of computer data transmission, indicating how many bits of data can be transmitted per second. In the field of computer network, bps is often used as a unit of measurement of network transmission speed. For example, gigabits per second (Gbps) means that one billion bits of data can be transmitted every second.
