1.JDBC Overview
By using the JDBC Api,java program, it is very convenient to operate the various mainstream databases, which is
simple functions. AG and IAD in the fixed network are responsible for user access, TG is responsible for interworking with PSTN, and the fixed gateway supports H.248 and MGCP protocols in terms of protocols. In addition to the H.248 Protocol, media gateway also needs to support the Bearer Control Protocol. If the mgws are carried by IP addresses, mgws must support IPBCPIP Bearer Control Protocol and IP Bearer Control Protocol) protocol. If ATM is used, MGW must support the Q.2630 protocol to ne

is quantified, the large input signal uses a large quantization interval, and the small input signal is small quantization interval, so it can be expressed with fewer digits in the case of satisfying the precision requirement. When sound data is restored, the same rules apply. In the nonlinear quantization, two correspondence relations are defined between the amplitude of the sampled input signal and the quantization output data, which is called the M-law-expanding (companding) algorithm and th

quite easy for us to draw a background. We enable face-to-face projection and draw a full screen image texture of the current frame. The following is the OpenGL ES1 code:

For fixed function hardware: OpenGL ES 1.1 is defined relative to the OpenGL 1.5 specification and emphasizes hardware acceleration of the API, but is fully backwards compatible with 1.0. it provides enhanced functionality, improved image quality and Optimizations to increase performance while loading cing memory bandwidth usage to save power. the OpenGL ES 1.1 extension pack is a collection of optional extensions added to OpenGL ES

Ordsets is an ordered set implemented by lists. because changes to data elements trigger re-sorting, ordsets is inefficient and only applicable to scenarios with small data volumes. ordsets contains common set operations: intersection, union, whether it is a subset, and whether there is an intersection
