Moore's Law means that the crystal hardware will be upgraded every 18 months, that is, the number of transistors in the integrated circuit will double every 18 months, and the performance of the processor will also double.

According to the accurate determination of scientific experiments, it is known that the number of carbon atoms in 12g carbon with a relative atomic mass of12 is about 6.02× 10 23. Scientifically, the collective containing 23 particles of 6.02×10 is regarded as a unit, which is called Mo. Mol is the unit (symbol n) representing the quantity of a substance, which is referred to as Mo for short, and the unit symbol is mol.

To sum up, Moore's Law has three versions:

1. The number of integrated circuits on an integrated circuit chip doubles every 18 months;

2. The performance of microprocessor doubles every 18 months, and the price is halved;

3. The computer performance that one dollar can buy quadruples every 18 months.

Among the above statements, the first statement is the most common, and the second and third statements all involve the price factor, and their essence is the same. Although the three statements have their own merits, one thing is consistent, that is, the period of "doubling" is 18 months, and "doubling" (or quadrupling) is the number of integrated circuits on an integrated circuit chip and the whole "computer performance".
