How much T is the calculation force 150m
Graphics cards can't dig out bitcoin right now. Your calculation power is the calculation power of Ethereum. The calculation method is also wrong
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

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

What does 1p mean
first of all, 1p computing power is equivalent to about 1.05 million g, which means that if you have 1g computing power of the whole network, you can get almost 1.05 million of bitcoin output of the whole network. According to the output of 3800 bitcoins per day, we can see that the daily income of 1g of computing power has dropped to 0.0036 bitcoins, which is about 2.7 yuan according to the current market price. If the electricity cost and mining machinery hardware cost are included, the profit is almost gone
secondly, 1p's whole network computing power seems amazing, but in fact, in a year's time, you will think it's just a pediatrics, because cointera will launch 2p miner in December, and bitmine will launch 4P miner in March next year. If these companies are not put in biochemical weapons by Syria, it should be expected that bitcoin's whole network computing power will reach more than 10p in a year's time, By then, 1g of computing power will only be able to dig 0.00036 bitcoins a day.
computing power refers to computing power, refers to that 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". The unit is written as hash / s, which is the so-called proof of work mechanism (POW)
in computer and peripheral disciplines,
1KB = 1024b kilo
1MB = 1024KB Mega
1GB = 1024MB Giga
1TB = 1024gb Tera
1PB = 1024tb PETA
1eb = 1024pb exa
in other disciplines,
1K = 1000 = 10 ^ 3
1m = 1000K = 10 ^ 6
1g = 1000m = 10 ^ 9
1t = 1000g = 10 ^ 12
1p = 1000t =10 ^ 15
1E = 1000p = 10 ^ 18
therefore, 150MB equals 157286400b, 150m equals 1500000000
note: K and KB are two different concepts and cannot be confused. Similarly, m and MB are two different concepts.

I hope my answer is helpful to you. Please accept it if you are satisfied. Thank you.
the time for people on the fast train to see the slow train passing the window is t = 200m / 25m / S = 8s
s total = 150 meters, t total = 10 + 5 + 15 = 30 seconds
so V average = s total / T total = 150 meters / 30 seconds = 5 meters / seconds
A: the average speed from a to B is 5 meters / seconds
this kind of question is whether the concept is clear. The average speed of a certain section of road must use the total distance and total time of this section of road
to solve the equation: 150x (T-10) = 90x (T-8), the solution is t = 13, and the distance is 150x (T-10) = 450
150 × 80 = 12000 M2 = 1.2 hA
