, this kind of structure server needs to have very large memory, when the system memory is sufficient, can alleviate the pressure of disk read operation, when the memory is low, the system will use virtual memory, the frequent use of virtual memory will increase the disk I/O increase, resulting in increased CPU consumption, and again affect the performance of the Web server. And network bandwidth is also a factor restricting high concurrent access, when the traffic is very large, the network ban
colours are called "complementary colors" when the two shades of light in the optics are suitably proportioned to produce a white sensation.
Complementary color is the most powerful color combination of hue, therefore, the rational use of complementary colors, can be a good contrast, highlighting the theme. We can make reasonable arrangements for the saturation, purity and size of the two colors to achieve harmony and unity. With a good complementar
can not use the general MB and Mbit conversion relationship (1b=8bit) to convert. For example, the official internal data transmission rate of a product is 683mbit/s, at this time can not simply think that 683 divided by 8 to get 85.375, it is considered that 85mb/s is the internal data transmission rate of the hard disk. Because in the 683Mbit also contains a lot of bit (bit) of auxiliary information, not exactly the hard disk transmission data, simple with 8来 conversion, will not be able to g
compare the advantages and disadvantages of xDSL, HFC and FTTX access technology.
For:XDSL technology is to use digital technology to transform the existing analog telephone subscriber line, so that it can carry the broadband service. Low cost, easy to achieve, but the bandwidth and quality of the large difference.The biggest advantage of HFC networks is its wide frequency band and the ability to take advantage of cable networks that already have considerable coverage. To transform an
category of copper for a data center cabling system to 6 categories, which are defined as Wanchaodo mode OM3, OM4, or Single-mode.
When it comes to fiber optics, as a new generation of wiring products, it's faster and less disturbed by the outside world. But can optical fiber become the inevitable trend of next generation wiring, and replace copper? Although the fiber is more advantageous in speed and security, it will be complementary to the copper
melting, the impact is not small, because we study people, education accounted for all the main part of life. The enrichment and expansion of academic content is proportional to the enrichment of the content of life. ”
There is no better language than the master suggested to the students, young designers are the most not affected by too many environmental, open-minded, full of passion and good ideals of a group, adhere to your ideals, to become top designer efforts.

Based on optics, the image measurement technology, which integrates optoelectronics, computer technology, laser technology, image processing technology and so on, has formed a new measurement technology in the field of measurement, and the image measurement system based on digital image processing technology has been widely used in the measurement of geometrical quantity, aviation and other remote sensing, Micro-dimension measurement and appearance me
precision and anti-fouling dual revolutionary breakthrough!
The illumination of optical system is higher;
The traditional optical mouse's light spot shape is relatively sparse, and the maximum illumination is only 1000Lux, while the ghost hidden wave intensity reaches 54400Lux, is 54 times times of the traditional optical engine, from the technical data analysis can be "phantom hidden Ghost Engine" Technology is more technologically superior than the past. To ensure that the mouse tracking mo
When does Huawei P9 out?
P9 press conference is April 6. Standard version of the price of 3088 yuan, a high version of 3688 Yuan
How about Huawei P9 mobile phone configuration?
Huawei "??" The pattern is suggestive of its dual-lens design. It is reported to be equipped with 5.2? 1080p screen, Kylin 950,3g/4g memory, 32GB storage, 1200W dual camera. Standard version of the price of 3088 yuan, a high version of 3688 YuanHuawei P9 adopts dual camera design, and it is equipped with the sensor com
Using near-loop (extension tube)
Near-loop is one of the inexpensive options, its principle is simple, that is, the distance between the lens and focal plane, creating a magnifying effect. The different thickness of the close-loop has different amplification effect, many times to see the near-loop is a group of three of the way to sell. Because the close loop is actually just a cylindrical ring, there is no optical structure inside, so ... Buy a deputy factory can be (but the more expensive OEM

there is an excess, the upper and lower lining lines are obvious, but the middle lining is slowly masked by the mask, and the text uses a shadow, which conforms to the background of the dark green to reflect the white font above.
The middle made a relatively light gradient, very friendly to reflect the three-dimensional.
The edge of the page body is also lined, to find it carefully
Then below is the use of the upper lining line, with shadows instead of the three-dimensional button desi

Based on the previous analysis, we concluded that modulation can be used for list link blue methods:By lowering the blue channel color level to reduce the overall saturation of the color (for example, adjusting the #0000ff to #000099), to avoid darkening, and black confusion, we can also increase the levels of other primary color channels and a
degree of customization. This customization can often increase the interest of these users in the product. Philips is seeing this, combining its own advantages in lighting and optics, to invent a customizable dynamic color T-shirt (lumalive) [10]. Our common traditional T-shirts have a fixed pattern, and this kind of T-shirt can be used to set the static or dynamic shape and color.

When using a thermal screen, you need to touch the screen with objects of a certain temperature. The optical touch screen is the use of sensors, through the invisible beam to divide the screen into many small grids, acc
We know that almost all the colours seen by the eye are made of three primary colors of optics: red, green, Blue (RGB) composition, and the computer wants to express 16581375 colors, it will not be silly to use the definition of 16581375 colors to express, as with nature, summed up the most basic three primary colors: R, G, B, You can determine the color of a pixel by just giving the ratio of three colors. What are the benefits of doing this? Obviousl
