1. There are rice balls, exo

2. The battery DBC
DB is a value that represents the relative value. It is a pure ratio, which only represents the relative relationship between two quantities. There is no unit. When considering how many DB the power of a is larger or smaller than that of B, the calculation formula is as follows: 10log (a power / B power). If the voltage ratio of the two is used, 20log (a voltage / b voltage) is used

[example] if the power of a is twice that of B, then 10lg (power of a / power of B) = 10lg2 = 3dB. In other words, the power of a is 3 dB higher than that of B. On the contrary, if the power of a is half of that of B, the power of a is 3 dB less than that of B

DBC is also a unit representing the relative value of power, which is exactly the same as the calculation method of DB. Generally speaking, DBC is relative to carrier power. In many cases, it is used to measure the relative value of carrier power, such as interference (co frequency interference, intermolation interference, intermolation interference, out of band interference, etc.) and coupling, spurious, etc. Where DBC is used, DB can also be used instead in principle

battery ADA will create a high-performance, low-cost and easy to manufacture lithium-ion battery, which can meet the power generation and storage requirements of military UAVs. The second phase of the study will be completed in collaboration with southwest nanotechnology and a major lithium-ion battery manufacturer.

3. It's like a hobbit. It has nothing to do with ADA.

4. At present, he is a friend. Lyon has a secret love for Ada, but people don't respond positively to him and always point a gun at his head ~ ~ but ADA Lyon also has special feelings, because the second generation nearly died in order to save Lyon, and he also says that he likes Lyon. But there is no ambiguous scene in 4 li. After playing biochemical crisis 2 and reading biochemical crisis comics, you will know clearly

5. I've never heard of IDA

6. Unknown_Error

7. If you want to listen well, it should be aandan, so you can be more tactful, hope to adopt.

8. Wesker set up a behind the scenes organization to reorganize umbrella company. ADA is his agent. He reappeared in biochemical 4 to capture the samples in saddler's hands. To put it simply, the relationship between the boss and his subordinates is not so obedient

first of all, we need to explain what CPU and GPU stand for. CPU is the central processing unit, GPU is the graphics processor. Secondly, to explain the differences between the two, we must first understand the similarities between them: both have bus and external connections, have their own cache system, and digital and logical operation units. In a word, both of them are designed to complete the calculation task
the difference between them lies in the structure difference of cache system and digital logic operation unit: Although CPU has multi-core, the total number is not more than two digits, each core has enough cache and enough digital and logic operation units, and it also has a lot of hardware to speed up branch judgment or even more complex logic judgment; The number of cores of GPU is far more than that of CPU, so it is called many cores (NVIDIA Fermi has 512 cores). The cache size of each core is relatively small, and the number of logical operation units is small and simple (GPU is always weaker than CPU in floating-point calculation at the beginning). As a result, CPU is good at dealing with complex computing steps and complex data dependent computing tasks, such as distributed computing, data compression, artificial intelligence, physical simulation, and many other computing tasks. Due to historical reasons, GPU is proced for video games (so far its main driving force is still the growing video game market). In 3D games, a kind of operation often appears is to perform the same operation on massive data, such as: to perform the same coordinate transformation on each vertex, and to calculate the color value of each vertex according to the same lighting model. The multi-core architecture of GPU is very suitable for sending the same instruction stream to the multi-core in parallel and executing with different input data. From 2003 to 2004, experts outside graphics began to notice the unique computing power of GPU, and began to try to use GPU for general purpose computing (GPGPU). After NVIDIA released CUDA, AMD and Apple also released OpenCL, GPU began to be widely used in the field of general computing, including: numerical analysis, massive data processing (sorting, map rec, etc.), financial analysis, etc

GPU is much better than CPU in terms of performance and power consumption

10. The CPU is still important for most computer operations. At least, the CPU and GPU should be coordinated. For example, when you play computer, the CPU utilization rate of e2200 is always above 20%, and that of e4500 is always below 10%, then you know the importance of a CPU.

If HD, 3D and games require high display performance, It is more important to choose a good graphics card than a good CPU when installing the machine, because the utilization rate of CPU is very low most of the time. ***
