Video card (graphics card) full name display interface card, also known as display adapter, is the most basic configuration of computer, one of the most important accessories. As an important part of the computer host, the graphics card is the equipment of digital to analog signal conversion, and it undertakes the task of output display graphics

the graphics card is connected to the main board of the computer, which converts the digital signal of the computer into an analog signal for the display. At the same time, the graphics card still has the ability of image processing, which can help the CPU work and improve the overall running speed. For those engaged in professional graphic design, graphics card is very important. Civil and military graphics chip suppliers mainly include amd (ultra micro semiconctor) and NVIDIA (NVIDIA). Today's TOP500 computer, including graphics card computing core. In scientific computing, graphics card is called display accelerator

2. 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 a mining machine can 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 soaring computing power environment, the arrival of P era means that bitcoin has entered a new stage of arms race. This is the meaning of computing power. I would like to know more about it Please accept)

3. Young people think too much. Let's watch the bitcoin documentary

4. Now bitcoin's listing is blocked!!! You still dig, you go to the internet post bar, bitcoin bar, take a look

5. According to the current mining difficulty, this computing power is basically unable to dig bitcoin. The calculation power is too small. Taking avalon2, the mainstream mole in the market, for example, 100g can only dig 0.0063 bitcoins a day. If you want to mine bitcoin, you need to buy the latest ASIC miner, and the energy consumption must be low. Otherwise, even if the example is high, no matter how much bitcoin you dig, you will be unprofitable, because the cost is too high. Of course, if the electricity charge is free, it is OK. Purchase mining machine to consider the overall mining machine, want to see if they have profits. It is suggested that you buy Avalon third generation miner for mining. I hope I can help you. Good luck!

6. 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.

7. The minimum monthly wage in Shanghai has been adjusted to 750 yuan, ranking the first in China. From September 1, the minimum monthly wage for employees in Shanghai will be increased from 690 yuan to 750 yuan, and the minimum wage for hourly workers will be increased from 6 yuan to 6.5 yuan. This is the 14th time in a row that Shanghai has raised the minimum wage system since it was first introced in China in 1993. Shanghai clearly stipulates that the minimum wage after the above-mentioned adjustment is the real income, and the basic social insurance premium and housing accumulation fund payable by indivials shall be paid separately by the unit. In other words, 750 yuan is the net income after excluding social security fees and other expenses, and this minimum wage standard is currently the highest in the country. At the same time, there are three policies to adjust the minimum living standard of urban and rural residents, the standard of pension subsidies for some special pension objects, and increase the remuneration for public welfare posts. For example, starting from August 1, the minimum living standard for urban residents in Shanghai has been raised from 300 yuan per person per month to 320 yuan; Starting from July 1, the minimum living standard for rural residents in the city will be adjusted from 2340 yuan per person per year to 2560 yuan per year. Yesterday, the Shanghai municipal government also approved the "opinions on special assistance for those who have agreed to retain social insurance relations" formulated by six departments, including labor security, medical insurance, civil affairs, finance, SASAC and the Federation of trade unions. This is another income distribution policy that benefits low-income groups. According to the policy, those who are within two years (including two years) of the legal retirement age who have achieved market-oriented employment and have been registered by the labor department can apply for employment subsidies ring the period of employment, and the subsidy standard is 50% of the minimum wage standard of the city in that year; For those who are unable to obtain employment e to serious illness or most of them lose the ability to work, and whose families have difficulties in living, they will be given living expenses subsidies. The subsidy standard is the minimum wage standard of the city in that year. The minimum monthly wage in Guangdong ranges from 450 yuan to 810 yuan. "Guangzhou workers whose monthly income is still less than 780 yuan can complain to the local labor supervision department or trade union." Starting from September 1, Guangdong will implement the new minimum wage standard for enterprises, which is the biggest increase since 1994. In order to make this security line not a mere decoration, the Department of labor and social security of Guangdong Province reminds workers to keep their eyes open and protect their own interests. According to the new plan, the minimum wage standard in Guangdong Province has increased by an average of 17.8% over the previous year. After the adjustment, the minimum wage standard of the province can be divided into five categories: one is 780 yuan / month, which is applicable to Guangzhou; The second category is 690 yuan, which is suitable for Zhuhai, Foshan, Dongguan and Zhongshan; 600 yuan for the third category; 500 yuan for four categories; Five categories: 450 yuan. At the same time, Shenzhen also raised the standard: 810 yuan / month in the special zone, and 700 yuan / month in Baoan and Longgang districts outside the special zone. This adjustment will directly benefit the low-income groups, especially the more than 23 million migrant workers in Guangdong, and alleviate the income gap to a certain extent. Huang Linyan, director of the wage Department of the Guangdong Provincial Labor and social security department, analyzed in an interview that the government's move will promote enterprises to change the mode of relying on low wage competition and enhance the attraction of Guangdong to migrant workers. At the same time, changing the mismatch between economic growth and personal income distribution is also one of the reasons for the adjustment. From 1995 to 2005, the GDP of Guangdong Province increased by 265.77%, while the minimum wage of employees increased by 89.2% on average, equivalent to 1 / 3 of the GDP growth rate. Fujian provincial government's general office recently issued a "notice on the announcement of the minimum wage standard in Fujian Province and the minimum wage standard for part-time employment hours in urban areas where cities are divided into districts". Starting from August, Fujian Province will adjust the minimum wage standard announced in 2005. According to reports, the minimum wage standard in Fujian will be between 400 yuan and 650 yuan. Among them, Siming District and Huli District of Xiamen City have the highest standard of 650 yuan, 50 yuan higher than last year's minimum wage standard; In some mountainous counties and cities in Fuzhou, Nanping, Sanming, Longyan and Ningde, the minimum wage was 400 yuan, 80 yuan higher than last year's minimum wage At the same time, the circular also announced the minimum hourly wage standard for part-time employment in the urban areas where the cities are divided into districts, of which the highest in Siming District and Huli District of Xiamen is 6.8 yuan / hour; The lowest in Sanyuan District and Meilie District of Sanming City, Yanping District of Nanping City, Xinluo District of Longyan City and Jiaocheng District of Ningde City were 4.5 yuan / hour, all slightly higher than the previous year. The person in charge of the labor and Social Security Department of Fujian Province said that the minimum wage is the minimum guarantee level for workers, not the actual wage level, nor the wage guidance line for enterprises and the wage guidance price for the labor market. It includes bonus, but does not include overtime pay and allowance under special working environment and conditions, as well as the welfare of workers stipulated by law and the state. The person in charge reminds workers to be alert to some unscrupulous owners who deliberately lower and exploit workers' e remuneration under the pretext of minimum wage standard. Qinghai has established the minimum wage standard for the first time. Starting from July 1 this year, Qinghai Province has adjusted the minimum wage standard. After the adjustment, the minimum wage standard for full-time workers will be greatly improved. At the same time, in view of the actual needs of flexible employment of employers and self employment of workers, Qinghai Province has also established the standard of hourly minimum wage for the first time. This adjustment is a large increase since the establishment of the minimum wage security system in Qinghai Province in 1995. After the adjustment, the minimum wage for full-time workers is 440 yuan per person per month in Xining and Haidong; Hainan, Haibei and Huangnan are 450 yuan per person per month; Haixi, Guoluo and Yushu are 460 yuan per person per month. The hourly minimum wage system is applicable to part-time workers. The specific standard is: the hourly minimum wage in Xining and Haidong is 5 yuan; The minimum wage of Hainan, Haibei and Huangnan is 5.1 yuan per hour; Haixi Prefecture, Guoluo Prefecture and Yushu prefecture have a minimum wage of 5.2 yuan per hour The regulations on minimum wage of enterprises was promulgated in 1993, and the Ministry of labor and social security formulated the regulations on minimum wage in 2004. In view of the long term and low level of the minimum wage standard in some areas, the new regulations clearly stipulate that the minimum wage standard should be adjusted at least once every two years
