How to make money from mining
Mining cooperate with all manufacturing instries
when digging things here, you can open a number there to fight magic stone and then sell some equipment. Basically, you can be self-sufficient
the higher the mine is, the more difficult it is Dig to prepare a few pieces of bread at any time to open the doctor number treatment
the methods of connecting LG network TV to wireless network are as follows:
1. Start the TV and enter the main interface of network TV
2. Use the remote control to find the system settings and press the Enter key
3. After entering the system settings interface, find the wireless network settings and press the OK key to enter
4. After entering, open the wireless network connection, search the WiFi signal nearby, find the WiFi signal sent by the home wireless router, click Connect, and input the WiFi password to establish the connection
5. After the smart TV is successfully connected to the WiFi signal, return to the main interface, and users can watch online movies, TV dramas and other online TV programs on demand.
A global currency can be exchanged for about 0.1 yuan RMB. It cannot be used for cash withdrawal
China global currency is a kind of virtual currency, which is not protected by law. Five ministries and commissions, including the China Banking and Insurance Regulatory Commission, jointly issued the "risk warning on preventing illegal fund-raising in the name of virtual currency and blockchain", pointing out that many criminals, under the banner of financial innovation, use virtual currency, blockchain, digital currency and other projects to speculate and fund-raising, even to engage in fraud, pyramid schemes and other illegal activities
extended information:
precautions for the use of digital currency:
under the framework of legal tender, the central bank has more direct power in controlling the money market. In terms of legal digital currency, the central bank's balance sheet is likely to expand significantly. But when the economic crisis and financial crisis occur, the central bank must provide more liquidity support to commercial banks
as long as the deposit of legal digital currency meets the conditions, the user can easily withdraw the deposit, which will trigger a payment crisis in a specific bank and trigger a chain reaction, which will lead to systemic financial risk
CXC virtual currency is a kind of illegal and fraulent behavior, which does not make money H2 >
because on September 4, 2017, seven ministries and commissions including the people's Bank of China issued an announcement, which clearly pointed out that the so-called "virtual currency" is essentially an unauthorized illegal public financing behavior, which is suspected of illegal sale of token bills, illegal issuance of securities, illegal fund-raising, financial fraud, pyramid schemes and other illegal and criminal activities
on August 24, 2018, the bank and Insurance Regulatory Commission and other departments jointly issued a risk warning, pointing out that some illegal elements, under the banner of "financial innovation" and "blockchain", issued "virtual currency", "virtual assets" and "digital assets" to absorb funds, which infringed the legitimate rights and interests of the public. This kind of activity is not really based on blockchain technology, but hypes the concept of blockchain and carries out illegal fund-raising, pyramid selling and fraud
< H2 > extended data:features
decentralization. Blockchain technology does not rely on additional third-party management institutions or hardware facilities, and there is no central control. In addition to the self-contained blockchain itself, each node realizes information self verification, transmission and management through distributed accounting and storage. Decentralization is the most prominent and essential feature of blockchain
openness. Blockchain technology is based on open source. In addition to the private information of all parties involved in the transaction is encrypted, the data of blockchain is open to everyone. Anyone can query blockchain data and develop related applications through the open interface, so the information of the whole system is highly transparent
independence. Based on consensus specifications and Protocols (similar to various mathematical algorithms such as hash algorithm used by bitcoin), the whole blockchain system does not rely on other third parties, and all nodes can automatically and safely verify and exchange data in the system without any human intervention
safety. As long as 51% of all data nodes cannot be controlled, the network data cannot be arbitrarily manipulated and modified, which makes the blockchain itself relatively safe and avoids subjective and artificial data changes
you can do this
a. Find out your motherboard model (two ways: 1. Take apart the host to see the motherboard model
2. After finding out the model,
go to another computer and install it
B. you can also find a ghost
XP system disk to install it again, so that the driver can be installed directly without manual operation.
if you can't, open the drive disk, find the driver of the Ethernet controller, and double-click it.
First of all, 232 and 485:
Application differences:
1. Different transmission modes
RS-232 adopts unbalanced transmission mode, which is called single terminal communication, while RS485 adopts balanced transmission mode, which is called differential transmission mode. RS-232 adopts unbalanced transmission mode, that is, the so-called single terminal communication. The data signals at the receiving end and the transmitting end are relative to the signal ground. For example, when using DB25 connector, the data sent from DTE equipment is 2-pin to 7-pin (signal ground) level
2, different transmission distance
RS-232 is suitable for communication between local devices, and the transmission distance is generally not more than 20m. The transmission distance of RS-485 is tens of meters to thousands of meters
RS-232 only allows one-to-one communication, while RS-485 interface allows up to 128 transceivers to be connected on the bus. The typical RS-232 signal swings between the positive and negative levels. When transmitting data, the positive level of the transmitter driver is + 5 ~ + 15V, and the negative level is - 5 ~ - 15V conversion principle difference:
RS232
so in fact, the signal source of both are UART, which converts the UART signal into the voltage of the driving cable and provides the driving ability
so strictly speaking, RS232 is not a fieldbus because it does not support multi node network and has poor anti-interference. RS485 as a fieldbus to apply, but also a lot of trouble, does not support non polarity, can not be arbitrary topology, can not supply power, large network must add terminal resistance, can not be shared with 220 v. If there are construction requirements for fieldbus, it is recommended to take a look at the two bus technology
Ethernet
the most basic difference:
different functions, RS485 is used to transmit control signals, Ethernet is through the Internet to obtain network data
different from using wire, RS485 can be transmitted with 2-core wire, while Ethernet must use 8-core shielded wire, and at least 4-core must be connected, and cannot be connected wrong
