What is the calculation power 1ghs

1.

computing power is a measure of bitcoin network processing power. That is, the speed at which the computer calculates the output of the hash function. Bitcoin networks must perform intensive mathematical and encryption related operations for security purposes. For example, when the network reaches a hash rate of 10th / s, it can perform 10 trillion calculations per second

in the process of getting bitcoin through "mining", we need to find its corresponding solution M. for any 64 bit hash value, there is no fixed algorithm to find its solution M. we can only rely on computer random hash collisions. How many hash collisions can a mining machine do per second is the representative of its "computing power", and the unit is written as hash / s, This is called workload proof mechanism pow

computing power provides a solid foundation for the development of big data, and the explosive growth of big data poses a huge challenge to the existing computing power. With the rapid accumulation of big data in the Internet era and the geometric growth of global data, the existing computing power can no longer meet the demand. According to IDC, 90% of the global information data is generated in recent years. And by 2020, about 40% of the information will be stored by cloud computing service providers, of which 1 / 3 of the data has value

therefore, the development of computing power is imminent, otherwise it will greatly restrict the development and application of artificial intelligence. There is a big gap between China and the advanced level of the world in terms of computing power and algorithm. The core of computing power is the chip. Therefore, it is necessary to increase R & D investment in the field of computing power to narrow or even catch up with the gap with the developed countries in the world

unit of force

1 KH / S = 1000 hashes per second

1 MH / S = 1000000 hashes per second

1 GH / S = 1000000000 hashes per second

1 th / S = 100000000000 hashes per second

1 pH / S = 100000000000 hashes per second

1 eh / S = 100000000000 hashes per second

4. As long as you dig more than 0.003 bitcoins and more than 0.1 Ethereum, you can directly mention that any exchange's income will arrive every day

5. Now it's about 0.03btc, you can find a special query website.

6. I54590 is a four core, four thread, three-level cache is 6MB. The i7 4790 is a 4-core 8-thread, 3-level cache of 8MB. CPU is not only determined by the dominant frequency.

Equivalent to 1.0336 kg of atmospheric pressure on an area of one square centimeter

The international unit of

pressure is Pascal, abbreviated as PA, and the symbol is PA. Other commonly used units are: bar (1 bar = 100000 PA) and CMHG (or CMHG)

because after conversion: a standard atmospheric pressure = 1.013 × 105 PA, 1 standard atmospheric pressure = 760 mm mercury column height

then a standard atmospheric pressure is equal to the weight of a 760 mm high mercury column, which is equivalent to 1.0336 kg of atmospheric pressure on an area of one square centimeter. Because the weight and length units used in different countries are different, so the pressure units are not unified, which is not convenient to compare and analyze the global pressure. Therefore, it is universally stipulated that & quot; HPA & quot; As a unit of air pressure

extended data

in terms of measurement methods, there are two kinds of commonly used measuring instruments in meteorology: liquid (such as mercury) barometer and solid (such as metal empty box) barometer

the pressure record is measured by the barometer or barometer installed in the air pressure chamber with little change in temperature and sufficient light. There are timing pressure record and continuous pressure record. The time pressure record of manual visual observation is measured by moving or fixed channel mercury barometer, which is observed 4 times a day at the basic station and 24 times a day at the reference station

The metal elastic film box is used as the sensor to record the time pressure, which can obtain the pressure record at any time. These instruments are used to measure the air pressure of the station, and the sea level air pressure can be calculated according to the sea level height of the station, the air pressure of the station, the air column temperature and other parameters

1bar=1.02kg/cm2 Bar is a unit of pressure. At least we need another area to calculate the force

about the pressure unit bar:

bar (symbol bar), millibar (symbol mbar, also known as MB) are. They do not belong to the international system of units or the centimeter gram second system, but they are accepted to be used in conjunction with the international system of units. Because bar is similar to atmospheric pressure, it is widely used to describe pressure. It is legally recognized in the countries of the European Union

1 bar (bar) = 100000 PA (kPa) = 100 kPa (kPa) = 1000000 dyn / cm2 (dyne / cm2)
1 mbar (mbar) = 0.001 bar (bar) = 0.1 kPa (kPa) = 1 HPA (kPa) = 1000 dyn / cm (dyne / cm2)
