Notes:
① The coordinates of the rectangular vertices must be re-sorted and used again. It is only a reference for discuss to say that the top is not strictly above the top, so we need to re-sort and re-use them in the lower order.
② Because the inside of the rectangle is also part of the rectangle, the line segment is considered to be at the intersection of the rectangle in the rectangle.
③ When determining whether the four sides of a line segment and a rectangle have intersecti
There are many users who use Cisco switches. When selecting their products, it is a headache to see Cisco switch models. Here we mainly explain how to quickly understand these complex Cisco switch models. The product line of the 2900 series is very long. Some of them are common 10/100 BaseTx Cisco switches, such as C2912 and C2924, some are with Optical Fiber interfaces, such as C2924C with two 100 BaseFx ports, and some are modular, for example, C 2924 M has two expansion slots. The expansion s

How does the array go horizontally?
Array6=>array (5=> ' Black xx ', 42=> ' XXL '),7=>array (5=> ' Black xx ', 40=> ' XL '),8=>array (8=> ' Ash ', 40=> ' XL '),);Results:Array0=>array (5=> ' Black xx ', 8=> ' ash '),1=>array (42=> ' XXL ', 40=> ' XL '),);
How does the array go horizontally and filter for duplicate values?

" means to expand the above calculation to two-dimensional space based on the influence of horizontal interpolation, and then calculate the influence of vertical interpolation. The dual-cube interpolation algorithm can produce relatively clear picture quality, but the computing workload also increases. This algorithm is most commonly used in many image processing software today, such as Photoshop, after effects, avid, Final Cut Pro, etc. In order to get better image quality, many new algorithms
technology, DSL2 integrated engine, 1.2 MB XGLite/4 MB General MIDI audio library, and allows users to load custom sound settings to SoundMAX synthesizer; you can even use some third-party software applications to create your own MIDI sequence and DLS sound settings. You can adjust the CPU usage within the range of 20%-80% when playing MIDI.
All of these outstanding features have boosted the performance of the common AC "97 sound card, so that numerous users of the AC" 97 sound card are excited

QoS
Data frames can be reclassified Based on the 802.1 p CoS value or the default CoS value specified by the network administrator for each port.
On the hardware, each output port supports four queues.
The WRR queue algorithm ensures that low-priority ports are not ignored.
