What does QC stand for in digital currency

1. bitcoin, of course, is the hottest one. In addition to bitcoin, there are also:
1. Litecoin is similar to bitcoin, which is also an encrypted digital currency, and its price has risen sharply recently. It is a P2P open source digital currency, which can be regarded as a branch of bitcoin. However, although lightcoin is based on bitcoin protocol, it does not require very high computing power. It can also be mined using ordinary computers. Lightcoin's algorithm comes from the algorithm designed by Dr Colin Percival for tarsnap secure online backup service (backup for Linux and other open source operating systems)
2. Namecoin
namecoin is also based on bitcoin, which is another branch of open source. Namecoin is a distributed DNS protocol -- generally speaking, it can transform the website name (such as ifeng. Com) that can be understood by human into the address that can be understood by machine. As its own DNS, this kind of currency can operate outside the normal Internet, so it can break away from the control of ICANN
the monetary value and domain name of namecoin are stored in the user's blockchain records, limiting the total number to 21 million
3. Peercoin
peercoin is a peer-to-peer variant of bitcoin, which can improve mining efficiency and security, and improve safeguard measures to avoid group mining. Now, group mining has been considered as a potential defect of bitcoin. According to the statistics of emerging currencies by coinmarketcap.com, peercoin currently ranks fourth in the market value of digital currencies
4. Primecoin
primecoin is a cryptocurrency similar to bitcoin, but it uses a completely independent mining algorithm. Bitcoin uses the hashcash algorithm, while prime coin uses the long Cunningham chains to create the value of money - a sequence of prime numbers named after mathematician AJC Cunningham
in the process of bitcoin mining, as the amount of money goes on, the difficulty will increase sharply. But prime is different. Every time a primecoin is mined, the mining difficulty will increase slightly, and the process is much more stable< 5. Feathercoin

based on the design of litecoin, released in April 2013, can adjust the mining difficulty more frequently than litecoin. Feathercoin will be updated frequently, adding new features and improvements to eliminate malicious mining behavior

6. Novacoin

another P2P digital cryptocurrency. Novacoin is different from most other currencies in that it integrates a protection mechanism in the currency core, which can identify illegal mining activities

the total number of novacoin is limited to 2 billion, which is considerable. If necessary, the total can be adjusted upward

7, infinitech

published in June 2013. A by-proct of litecain. According to the mining situation and the total amount of money, infinite money can frequently adjust the mining difficulty ratio< Megacoin was only released in the fourth quarter of 2013, imitating bitcoin in the early stage. The total number of megacoin is limited to 42 million, which can be mined like other virtual currencies. Its biggest selling point is brand publicity, which other digital currencies lack< It was released in 2013 and is still in its infancy. In the security part of quarkcoin, nine independent loops are deployed and six different algorithms are used.

2.

Dog money has now gone up far more than 250% to about 430%. Dogcoin refers to a kind of virtual currency, which means the same as bitcoin. According to the news from Wall Street, within 24 hours, the dog compared with his family achieved a reversal, successfully breaking through the trading price of $0.044. This can be said to break the rumor that dog money has been hollowed out. It is precisely because of this that many people begin to pay attention to the investment channels of dogcoin. After all, dogcoin has now reached US $5.64 billion and has successfully become the second largest virtual currency after bitcoin. So today we will discuss some problems behind dog coin{ RRRRR}

Third, how to view some news about dogcoin

to be honest, I feel that the news of dogcoin appears suddenly, which is the same as that of bitcoin. Many people say that you have found the wealth code by investing in dog coin, but in my opinion, if such wealth code is easily told to you, then it must be very cheap. Even now, some people predict that the price of dog coin can exceed 100 million US dollars. If so, its market value may exceed that of bitcoin. In my opinion, there must be a pusher behind the sudden explosion of dog coin. It is impossible for these retail investors to raise the price of dog coin

3. QC's full name is quality controller, who is responsible for inspecting procts and controlling quality. As the name suggests, clothing QC is the person who controls the quality of clothing. According to my understanding, QC and inspector are two different concepts. The focus of QC is control, so that the company can get good quality procts; However, the inspector only passes the inspection to judge whether a batch of goods are qualified (pass or fail), so as to avoid the company receiving unqualified procts. But now most people confuse QC with inspector. Let's call it QC here. Some companies only conct a final inspection on each garment before shipment; In some cases, at least one intermediate inspection and one final inspection are required; Some even need to carry out quality control in the whole process of garment proction, and carry out many times of early inspection or in-line inspection, so as to find and solve problems as early as possible

QC seven methods are commonly used statistical management methods, also known as primary statistical management methods
the old seven QC methods refer to: checklist, hierarchy method, Plato, cause and effect diagram, scatter diagram, histogram and control diagram
the new seven QC techniques refer to: affinity diagram method, association diagram method, system diagram method,
matrix diagram method, arrow diagram method, PDPC method, matrix method and data analysis method.

5. QC is the abbreviation of quality control in English. Its Chinese meaning is quality control. Its definition in iso8402:1994 is "operation technology and activities adopted to meet quality requirements". Some organizations that implement ISO9000 will set up such a department or post to be responsible for the quality control functions required by ISO9000 standards. The personnel who take charge of this kind of work are called QC personnel, which are equivalent to proct inspectors in general enterprises, including IQC, IPQC and FQC<

IQC (incoming quality control) means the quality control of incoming materials, referred to as incoming material control

IPQC (input process quality cortrol), which means process control in Chinese, refers to the quality control of the proct from material input to final packaging

OQC
OQC the finished proct must be inspected before leaving the factory, so as to achieve the goal of zero defect, zero customer satisfaction and zero complaint. Inspection items include: finished proct packaging inspection: whether the packaging is firm, whether it meets the transportation requirements, etc. Finished proct identification inspection: if the trademark batch number is correct. Finished proct appearance inspection: whether the appearance is damaged, cracked, scratched, etc. Functional performance test of finished procts. If the batch is qualified, it shall be released. If the batch is unqualified, it shall be reworked or repaired in time until the inspection is qualified

QA
QA is the abbreviation of quality assurance in English, which means quality assurance in Chinese. Its definition in iso8402:1994 is "all planned and systematic activities implemented in the quality management system and verified as needed in order to provide sufficient trust to show that the entity can meet the quality requirements". Some organizations that implement ISO9000 will set up such departments or posts to be responsible for the quality assurance functions required by ISO9000 standards. The personnel who undertake such work are called QA personnel

1、 QC is to do: quality control, make it meet the standard requirements; It means "quality control"

QC is the abbreviation of quality control in English and "quality control" in Chinese

Third, QC's work:

QC's work is mainly the inspection of finished procts, raw and auxiliary materials, etc. QC is a quality assurance for the whole company, including the release of finished procts, raw and auxiliary materials, the normal operation of the quality management system, etc

in the history of quality management, "QC" appeared first, and it is the most basic requirement of quality management that the procts are delivered after inspection. QC function is to control the proction process and analyze the process data, and provide relevant information to other departments

extended data:

1. It mainly analyzes and discusses specific work errors or poor quality by using QC tools, and arranges the results in places that are easy to see, so as to remind you to prevent such problems, and you can put forward new suggestions and discuss and revise them at any time. It is generally suitable for single work or specific project activities, not for every small project

2. It is the most basic requirement of quality management to ship the procts after inspection. The purpose of quality control is to eliminate the factors that cause unqualified or unsatisfactory results in all stages of the quality loop by monitoring the quality formation process

Some organizations that implement ISO9000 will set up such a department or post to be responsible for the quality control functions required by ISO9000 standards

QC is a quality assurance for the whole company, including the release of finished procts, raw and auxiliary materials, and the normal operation of the quality management system

7. Structured interview. It's the same as the civil service examination. In addition, the written test is not difficult, just look at the outline.

8. You're right. Most scientific research stations are located around Antarctica, so they can get better supplies< There is no scientific research station in the Antarctic Center
both the South Pole and the North Pole have been reached by human beings
it's difficult to get there, especially at the South Pole
the coldest place is Antarctica, which is colder because of its high altitude and thin air.

9. Blizzards, polar bear attacks, cracks in the fallen ice, icebergs collapsing, most likely lack of food and fuel, psychological fear ring the investigation, mental disorder. That's all I can think of
