height.
Therefore, if the resolution is 1024, it is better to set your webpage to 1000 security. As shown in the following figure, the white space on both sides is larger, making it more visual and convenient to design floating layers.
Generally, the resolution is set to 800 for 770. But it is also set to 760.
These need to be understood and kept in mind, otherwise it is likely that they do not meet the requirements of the browser, But we generally s

Nowadays, many website advertisements are in full swing. Now I will introduce the common code usage methods for floating couplet advertisements. The results are displayed at a resolution of 1024*768, the image can be automatically hidden at a resolution of 800*600 to avoid page hiding affecting the visitor's browsing content. The following code is required to achieve the effect:
Code:

Density-independent pixel (dip)
The Unit for calculating the logic density. The formula for the dip and the specific pixel value is dip/pixel = dpi/160, that is, px = dp * (dpi/160)
2. DPI Value Calculation
For example, calculate the WVGA (800*480) Resolution, 3.7 inch density DPI, as shown in 1
Figure 1
Diagonal pixel indicates the pixel value of the Diagonal line (=), DPI = 933/3. 7 = 252

rolled back.Flashback query can be used to construct a query record set in multiple ways. The record set range can be time-based or SCN-based. It can even be used to query the front image of records in different transactions in the Undo tablespace at the same time. The usage is very similar to the standard query. To use the flashback query to query undo data, the simplest method is to keep up with the as of Timestamp (based on time) after the name of the standard query statement) or as of SCN (

Now a lot of website advertising to do in full swing, now I would like to introduce the common couplet floating advertising effect of the code use method, introduced this effect, in the 1024*768 resolution of the normal display, in the 800*600 resolution can automatically hide, so as not to cover the page affect visitors browsing content, Here is the code needed to implement the effect:

DDR2 refers to 2 generation of memory, memory is divided into DDR (1 generation), DDR2 (2 generation), DDR3 (3 generation), of course, performance comparison, 3 generation of performance >2 generation of >1 generation. As for similar to DDR2 800 here 800 refers to the memory bus fre
Many web design in the design of the Web page layout, the interface of the width of the page design are more confused, 800*600 size and 1024*768 size of the resolution, the page should be designed to how many pixels is appropriate? The horizontal scroll bar will appear when it is too wide, Below we will explain the standard dimensions of Web design.

For example maxthreads=1000,maxconnections=800, assuming a moment of concurrency of 1000, then eventually the number of Tomcat threads will be 800, that is, processing 800 requests at the same time, the remaining 200 into the queue "queued", If acceptcount=100, then 100 requests will be rejected

-independent Pixel (DIP)
Refers to the logical density unit of calculation, dip and specific pixel value of the corresponding formula is dip/pixel=dpi value/160, that is, PX = DP * (dpi/160)

Diagonal pixel represents the pixel value (=) of the diagonal, dpi=933/3.7=252
