What's the meaning of 8 kinds of calculation power in sum sof

1.

bitcoin mining machine is a kind of computer used to earn bitcoin. This kind of computer generally has professional mining chips and works in the way of burning graphics card, which consumes a lot of power. It is one of the ways to get bitcoin that users download software from personal computer and then run specific algorithm to get corresponding bitcoin after communicating with remote server

mining is actually a competition of performance and equipment, and a competition of computing power among miners. Miners with more computing power are more likely to dig bitcoin. With the increase of computing power in the whole network, it is more and more difficult to dig bits with traditional devices (CPU, GPU). People have developed chips specially used for mining. Chip is the core part of mining machine. The process of chip operation will proce a lot of heat, in order to cool down, bitcoin miner is generally equipped with heat sink and fan

bitcoin is a kind of virtual currency. Bitcoin mining system is the process of carrying out mathematical operation for bitcoin network through computer hardware. Miners who provide services can get a reward, because the network reward is calculated according to the tasks completed by miners, so the competition for mining is very fierce

bitcoin mining started with low-cost hardware such as CPU or GPU, but with the popularity of bitcoin, the mining process has changed greatly. Nowadays, the mining activities are transferred to the field programmable gate array, and the hash speed can be achieved through optimization. The mining efficiency of this mode is very high

2.

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

3. If you want to trade this computing power, you can trade it online. You can trade it on their app

4. Computing power (also known as hash rate) is a measure of bitcoin network processing power. That is, the speed of computing hash function output for computer (CPU). 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 the computer's 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 the so-called proof of work mechanism (POW)

recently, bitcoin's network computing power has entered the era of P computing power (1P = 1024t, 1t = 1024g, 1g = 1024m, 1m = 1024k). In the ever-increasing computing power environment, the arrival of P era means that bitcoin has entered a new stage of arms race

computing power is a measure of the total computing power of the unit that generates new blocks under certain network consumption. The single blockchain of each coin varies with the time required to generate a new transaction block.

5. Yes, pay attention to the backup of the wallet. I feel that the cold purse may not be so safe. I usually use the online wallet, which is very good. As for the safety factor, it's guaranteed by the company behind. I think it's reliable. Download your wallet, in case you forget the backup, or the backup is lost, there will be a big problem. It is said that many people have lost money.

6. First of all, we must concentrate our thoughts, take each question seriously, and check it after we finish it. Of course, if you do too many calculation problems, you need to improve your time efficiency.

good luck ~ ~
draft is very important in calculus.
I don't know how you draft it.
draft can't be too sloppy. A topic should be written down step by step, and it can't be omitted at the beginning.
try to use "circle, circle, circle, circle, circle, circle, circle, circle, circle, circle, circle, circle, circle, circle, circle, circle, circle, circle, circle, circle It's also helpful to cross out the data you don't want in time.
when the correct rate comes up, you can improve your speed and do mental arithmetic more simply.
first of all, you should practice oral arithmetic, simple addition, subtraction, multiplication and division, and remember some common numbers, For example, what is the square of each integer from 11 to 19? We remember it in primary school
secondly, improve the ability of vertical calculation, especially multiplication and division. Don't laugh. It's a basic skill.

7. 1. Hejijiabao is an intelligent robot terminal equipment with computing power center for family use under hejisoftware, a domestic blockchain technology R & D enterprise. The price is about 20000 yuan. Compared with similar procts, it can now dig dozens of mainstream currencies, with safety and low noise
2. Mining with several Jiabao is simply to confirm the network transaction and ensure the security of the whole digital asset network system by using the hardware equipment of several Jiabao and the mathematical problem of computing power. In return, you can get a certain amount of digital asset reward. Mining digital currency itself is a kind of property, which can be traded or exchanged through the trading platform.

8. I went online in the morning. I saw news related to software blockchain technology on the Internet two days ago. It is said that Heshu software is going to hold a new proct launch of Heshu laikelib blockchain.

9. In fact, every miner is almost a fool to operate, so it doesn't need too professional technology. You just need to buy a better miner and operate it according to customer service requirements. Here, we recommend and several Jiabao. It has big computing power, low noise, safety and power saving.
