According to the requirements of China's DDN technical system, the basic methods of user access such as, in these basic methods can also adopt different combinations.
1. Second-line analog transmission
Allows you to simulate inbound connections. In the exchange mode, you must transmit both the DC loop and the E M signaling of the PBX trunk line.
2. Two-line or four-line communication with MODEM
The supported user rate depends on the line length
How does PHP obtain the search engine and keywords of the inbound website. Sometimes, when we enter a website from a search engine, there will be a line of small words, "Welcome from Google Baidu, by retrieving the" XXX "keyword to this site" and so on.

The syn_sent status indicates a request for connection. When you want to access the services of other computers, you must first send a synchronous signal to this port. The status is syn_sent. If the connection is successful, it becomes established, at this time, the syn_sent status is very short. However, if syn_sent is found to be
As a result of Data Structure jobs, I have a serious understanding of the inbound stack, but it is actually very well grasped. The following code is successfully debugged on vs08, which contains detailed procedures for Stack-to-stack operations. I use the stack data type as an example, because it seems that the volume type is not found on the internet... I simply modified the stack of the integer data type ~

Define the structure of the XML file
Provides syntax and rules for XML
Why:
XML must have a correct structure for correct data exchange
The DTD specifies the layout and order of the content in XML, so that the XML that does not meet the requirements cannot be displayed.
Schema
Schema describes the structure of XML documents. schema is an XML-based DTD substitution (XML schema definition), also known as XSD. It is more powerful than DTD and can be expanded to meet future needs and
