first of all, make sure that the IP used by the computer is the public IP, so that any computer connected to the Internet can access the computer through this IP. Of course, most of the people at home and abroad use PPPoE to dial the Internet. They need to use a series of IP binding tools, such as peanut shell, to bind the IP after each dial, so as to achieve the purpose of real-time analysis. However, the bandwidth of most working families is between 2M and 8m, which is only suitable for 30 or 40 people to be online at the same time.

You can know from its "helicopter like roar", and the operating environment is also very luxurious, with 24-hour air conditioning, st-free, fire-proof, shockproof and so on. It also supports hot swap. The motherboard has more than 6 layers of PCB, and the power supply is rendant. It can be replaced without shutting down. The memory also has heat sink. However, the commonly used working home computer host does not have these conditions, and the configuration is not good, long-time work, it is likely to lead to high CPU temperature, running full, system failure

7. There are two pricing methods of exchange rate: direct pricing method and indirect pricing method

(1) direct pricing method
direct pricing method, also known as payable pricing method, is to calculate how many units of domestic currency should be paid based on a certain unit of foreign currency (1, 100, 1000, 10000). It is equivalent to calculating how much local currency should be paid for purchasing a certain unit of foreign currency, so it is called payable pricing method. Most countries in the world, including China, adopt the direct pricing method at present. In the international foreign exchange market, Japanese yen, Swiss franc and Canadian dollar are all directly priced, such as Japanese yen 119.05, that is, one dollar against 119.05 yen

under the direct pricing method, if the amount of foreign currency converted into local currency of a certain unit is more than that of the previous period, it means that the value of foreign currency rises or the value of local currency falls, which is called the rise of foreign exchange rate; On the contrary, if you want to use less local currency than before, you can exchange the same amount of foreign currency, which means that the value of foreign currency falls or the value of local currency rises, which is called the decline of foreign exchange rate, that is, the value of foreign currency is directly proportional to the rise and fall of exchange rate.

The exchange rate shows how much the first currency is worth in terms of the second currency. Let's take an example.

In the foreign exchange market, the U.S. dollar is generally considered as the base currency in the quotation, that is to say, all quotations indicate how much other currencies one dollar is equal to. But in the foreign exchange market, the pound, euro, Australian dollar and New Zealand dollar are exceptions
at present, the eight most frequently traded currencies are known as the main currencies, which are USD, EUR, GBP, CAD, JPY, NZD, CHF or SFR and aud respectively. All other currencies are called secondary currencies. At present, the main analysis in the foreign exchange market is USD, JPY, GBP, EUR and CHF. These currencies are the most liquid in the world, and also the most suitable for trading.
