2. Digital currency K-line chart, you can go to the bitnet exchange to view, as for technical analysis, there will be professional analysts to guide the operation.
3. According to my experience, the most dangerous moment in the stock market is when the bull turns to bear, when the rally ends and the bear market begins to plummet. How do we deal with it? First of all, you need to have a basic judgment on the general trend. You need to know whether it is a bull market or a bear market. Second, you need to have an understanding of technical analysis. At least you know where the general support level is. Then you can choose a good stock. Finally, you know how to value indivial stocks. It is suggested that you learn the discounted cash flow method of Warren Buffett, which is not bad. This is the investment idea of planting crops according to the season. By the way, the dawn is between the end of 19 and the middle of 20. GZH Lefu life
4. In the early hours of 16, Apple's A14 bionic processor is the fastest mobile chip on earth. CEO Cook Kwai said it was faster than the best computer win processor on the market. He said that the best seller is actually the lowest end. How low-end is there? A14 is a 2 + 4 six core, and naturally the target is the lowest end Intel six core
in this case, cook is playing word games. He said the lowest end six core. Intel has only two six cores. One is i9 10xx, and the other is the 32nm i7 980 of core generation.
although the i9 is six core, its performance is far less than that of i7 980 10 years ago, so cook estimates that his mobile phone chip is much faster than that of PC processor 10 years ago
therefore, only apple can say so or dare to say so, and anyone who leads the instry can boast so. But it also reflects that a fingernail sized SOC of a mobile phone needs to integrate a large number of other components besides CPU. Is the most high-end electronic technology procts. The CPU of a computer the size of the palm of an alt's hand has only a processor circuit on the chip. So the two are basically comparable
I think apple is a bit arrogant, but I still look forward to the launch of Apple's first self-developed PC processor with arm architecture next year. It's a mule, it's a horse.

5. At present, the main parameters used to measure the performance of mobile phone CPU are: main frequency, number of cores and manufacturing process. The same CPU can have different main frequency versions. For example, the main frequency of Huawei u8800 +'s Qualcomm 8255 CPU is 1GHz, which becomes 8255t1.4ghz when it comes to Huawei u8860 glory. In fact, it is the same. It can also be said that it is the manufacturer's overclocking and the performance is greatly improved. In addition, any electrical appliances can't avoid electron migration when they are powered on, especially the high-precision components like CPU are very sensitive to electron migration, and overclocking will make the gas temperature higher, aggravate electron migration, so it will rece the life of CPU. Under the same main frequency, we should choose the one with more advanced proction technology, more core quantity and newer architecture. In terms of mobile phone CPU ranking: Texas Instruments, Qualcomm (strong game performance and low price, but low music processing capacity), Intel (too high cost), apple, NVIDIA, Samsung (Samsung's CPU and Android system are the worst compatible), etc. I hope my answer will help you.
6. Powerful system and huge application is the key... It is said that the hardware is strong, but the software is weak. It's not the same system... It doesn't mean much more than hardware.
7. Limited by space and power, mobile phone CPU can't do the same as computer CPU. But there are also differences between mobile phone system and computer system. It's OK to run smoothly. At least it's OK to run a single application. It's just that you can't run multiple programs at the same time as a computer
there are two directions for the development of computer, one is towards mass storage and high performance. The other is low power consumption and miniaturization. Mass storage and high performance will inevitably lead to high power consumption, while low power consumption will inevitably limit the improvement of its performance. Have you ever seen a mobile phone with a cooling fan? Therefore, the processing power of arm can not be compared with that of PC processor. The addressing capability of 32-bit PC can reach 4G, and the addressing capability of 64 bit PC can be calculated by yourself. In theory, the addressing capability of arm is only 64K at most. In fact, we only need more than 10k at most
secondly, they are computers with different structures. PC is a computer with von Neumann structure (Princeton), while arm is a computer with Harvard structure (now it seems to use the improved Harvard structure), and the instruction structure is also different. PC (refers to the common x86 CPU) uses complex instruction system (CISC), while arm uses reced instruction system (CISC), (but it's not absolute. Apple's PC uses Motorola's CPU, and it also uses reced instruction)
most arm's floating-point operation ability is very weak, and they are generally used for fixed-point operation (except those specially designed for floating-point operation). If a small amount of floating-point operation is necessary, fixed-point operation can be used to simulate floating-point operation, and the result is the same, However, the process is actually done by fixed-point, which is not as fast as the floating-point processor, but it is also very efficient. It can replace the floating-point processor in the situation of low real-time requirements
as for the graphics processing capability, we can see how to compare them. Compared with the dedicated graphics processing chip, these two are rookies. However, in practice, we usually separate the graphics processing tasks and let the graphics processing chip work together with the CPU as a coprocessor to rece the burden of the CPU and save CPU resources for other purposes.

9. Virus features: when the computer is in use, the screen will suddenly go black. At this time, please unplug the network cable to prevent the virus from invading, then install the patch, and then back up the file and connect to the network again (the patch will be distributed to each other through the network management). At the same time, use 360 security guard or computer manager to update the patch.
