What determines notebook computing power
also playing online games, mobile phones with higher computing power are more fluent, and those with less computing power will get stuck
if you want a mobile phone to have higher computing power and play games without jamming, you need not only more core and higher frequency CPU, but also more memory and more stable and fast network
therefore, network, storage and computing power are the three main factors that determine the computing power of mobile phones. You can go to the tenth power computing platform to learn more about computing power and get free computing power.
At the end of 2017, digital currency experienced explosive growth and Waterloo like decline in 2018, and now it tends to be stable. During this period, a large number of investors poured into the currency circle, and all kinds of digital currencies need to be bought and sold through exchanges or digital currency wallets. However, in 2018, there were frequent incidents of exchange digital currency theft, so more and more traders chose to store digital assets in digital currency wallets, Sort out the five most well-known digital currency wallets and let's get to know them
Bitpai (score: 8.5)
bitpai is a comprehensive blockchain asset service proct based on HD wallet. Its main functions include: sending and receiving, buying and selling, accelerating transaction, etc. The user controls the private key, and the coin after the transaction is completed is directly kept by the user. At present, the currencies it supports mainly include BTC, BTC, ETH, some erc2.0 tokens, qtum, HSR, dash, safe, LTC, LCH, Zec, etc and Doge
advantages: the balance of the current digital currency can be displayed at the top of the front page of the wallet, and the upper left corner can be switched to other digital currencies, and the currency balance can also be switched from quantity to legal currency value. There are many functions in the middle, such as issuing currency, receiving currency, one click trading, etc. the broadcast of each transfer transaction is displayed below, and the completed transaction can also be queried in the transaction record. After leaving the bitpai app interface for a period of time, you need to unlock it when you re-enter, which improves the security of the wallet
deficiency: Only Mainstream currencies are supported, other small currencies are not supported, and the number of currencies is 10 +. The page setting is not user-friendly, and various parameters make it difficult for users to use. In addition, the security is worrying: Recently, there is a problem with bitpai IOS version, and the application can't be opened, and the official said: if you unload it carelessly, the assets in your wallet may not be recovered! It's still in Apple communication

simply from the perspective of pure mathematical calculation ability, the human brain can not be compared with the computer. The calculation ability of the computer is much stronger than that of the human brain, which is not only fast, but also very accurate. For example, the floating-point computing power of ordinary computers equipped with i5 processor at home can exceed 10 billion times per second, which far exceeds the computing power of human brain. In contrast, the computing power of human brain is pitifully low. Take the cumulative calculation of 1 + 2 + 3 + 4 + 5 +... + 100 (regardless of the simple algorithm, it is calculated according to the formula). The computer can calculate it in less than 1 millisecond, and it will not make any mistakes. However, it may take more than ten minutes for people to calculate, and it is very likely to make mistakes
however, it is unscientific to measure it only from the pure mathematical calculation ability. Human brain has intelligence, which is a function that all computers in the world can't achieve perfectly. The human brain has the intelligence that the computer can't match. In this respect, the human brain is much more powerful than the computer.
Generally speaking, the computing power is affected not only by the processor, but also by the chipset, memory and hard disk
from the perspective of parameters, performance
processor: model, core, main frequency, front-end bus, cache
chipset: type
memory: type and capacity
hard disk: capacity, cache, speed
it can be seen from the configuration of a laptop that the processor, chipset and memory are the key to the performance. For example, the processor model, main frequency, chipset model, memory type, capacity; We can only see the size of the capacity of the hard disk in the configuration, but we can't know the speed and cache size (except for software testing)
the strength of the overall computing performance is closely related to the balance of the configuration of the above four main components. If the processor and hard disk are compared to the two sides of a river, then the memory is the bridge connecting the two sides. For example, the wider the "bridge", the more people will pass at the same time. Therefore, large capacity memory has an absolute advantage over small capacity memory. If the "bridge" is narrow, there will be a bottleneck between the processor and the hard disk, which will affect the computational performance in actual use. Chipsets mainly support al channel memory. At present, almost all the chipsets used in commercial laptops support al channel memory, so we won't give a detailed description here
e to different batches of laptops with the same model and configuration, there will be some differences in the configuration of hard disks. These differences are shown in the speed of the hard disk, cache. The higher the speed of the hard disk and the larger the capacity of the single chip, the more data can be read per unit time

Seeing that many people could not pay their taxes, he sympathized with them and used the magic of turning stone into gold, Tax exemption for the people.

the annual report of an enterprise means that the board of directors is prepared to report the relevant financial situation of the company's business activities to the relevant competent departments and the general meeting of shareholders, and put forward in the form of written report materials. So what are the consequences of companies not reporting? What is the impact on the shareholders' meeting? Consequences of the company's failure to report: for the company's annual reports, the competent authorities will continue to conct random inspections throughout the year. If it is found that the company has not yet reported its annual report, the company will be included in the exception list. Even if the company will handle and delete the exception list in the future, it will keep the corresponding black record. Enterprises entering the exception list will not be able to handle changes, cancellations and other matters
Generally speaking, listed companies that fail to disclose their annual reports often suffer from defects in governance structure, formalization of internal risk control, weak awareness of compliance disclosure, non-standard financial accounting and inability of senior managers to perform their ties the China Securities Regulatory Commission has investigated 18 listed companies that have not disclosed their annual reports for three consecutive years. According to the previous survey results, behind the listed companies' illegal disclosure and non disclosure of important information, there are often hidden illegal related party transactions, illegal occupation of funds and vicious interests. Convey clues about serious crimes. The China Securities Regulatory Commission found that the company not only failed to disclose information in a timely manner, but also had fictitious purchase contracts, false payment services and blank endorsements. The company imposed administrative penalties and handed them over to the public security organs. For such companies, investors need to keep their eyes open and avoid stepping on thunder
