How to check the computing power of ordinary computer

1.

at present, the computing power of bitcoin in the whole network has reached 2.36 billion hash collisions per second, which is equivalent to the number of water droplets in more than 200000 50 meter long standard swimming pools. But even with such a large amount of computing power, it will take about 10 minutes to hit a hash value that meets the requirements

in 2012, bitcoin's output was halved for the first time, and in July 2016, bitcoin's output was halved for the second time. At present, 12.5 bitcoins are awarded for recording one page of account book. The next halving will take place around 2020, and the total number of bitcoins will not increase by 2040, with a total of 21 million. In other words, the difficulty of digging bitcoin is increasing, while the time required is increasing

2. 1. The meaning of CPU calculation once is that CPU performs "bit calculation" once, for example, 2 + 3 = 5, and binary is 0010 + 0011 = 0101. If there are three bits in total, the computer will calculate three times. 2. As for what this number is related to, that is, the higher the CPU frequency, the more the number of operations per unit time

3.

The steps are as follows:

1. Add a mine pool. 2. Download the software. 3. Start digging after setting

however, it is suggested that the building owner give up and dig bitcoin mainly depends on the GPU, that is, the processing chip on the graphics card. The home computer integrated graphics card can't be g at all. If the independent graphics card is NVIDIA chip, it's basically useless, because the most computing power is 160m / s

according to the income ratio, the calculation power of the machine is less than 8g / S (8192m / s), even the electricity fee is not enough, so it's meaningless to dig with a home computer for more than ten yuan a month. If you really want to dig, you should buy a mining machine

4. One bitcoin is now down to $135
one dollar equals 6.14
in other words, 1 bitcoin is equivalent to 828.9 yuan
and according to the latest news, bitcoin has been stolen, so the price will be lower.

5. The work done by gravity is related to the initial and final position of the object, but not to the path

work w = - Mg * (z2-z1) = - 100 * 9.8 * (2-8) = 5880 (Jiao)

[welcome to inquire, thank you for adopting!]

6. There are different instruction sets.
if you play 360 games with PC through simulator,
you are in a circle.
you should understand the story of tortoise and rabbit race

7. Maybe you should go to see Zhou Wei, the most powerful brain. He was bullied by his classmates every day in the fifth grade, but he is really a genius. Therefore, human brain is invincible, just because there is no such person.

8. It's obviously the wrong description
first of all, the CPU of home computer can see the floating-point operation, just download the corresponding software to test the floating-point operation of CPU, single precision / double precision and so on
secondly, floating-point operation only shows the performance of household CPUs. On the one hand, some CPUs are too high to reflect your daily application
for example, compared with the old core architecture, the new core architecture with fewer cores has lower total score, but stronger single core performance.
