关于通讯基本概念的介绍容易混淆的东西很长知识-on communications on the basic concepts of easy to confuse things a very long knowledge

资源描述 UDP是轻量级，不可靠，面向数据报的，无连接的协议，也能够与可靠性不是非常重要的情况下。 在Qt平台下编程，实现简易的本地主机的UDP报文传输。 QUdpSocket类用来发送和接受UDP数据包，这里的Socket简单来说就是一个IP地址和一个Port端口号，其中IP地址制定了网络中的一台主机，而端口号制定了该主机上的网络程序，这样使用套接字就可以实现网络上两台应用程序之间的通信。

说明：多线程 (Multi-Thread) RS232 串行口通讯构件 ，是 COMM32.ZIP 构件的改良版，并且增加 Data Bits、Parity、 Stop Bits 等配置，支持 Read/Write 时序控制 (Timing control)、 ReadIntervalTimeout、 WriteIntervalTimout 等 ，支持 DTR/DSR, RTS/CTS 硬件流程控置及 Xon/Xoff 软件流程控置 ( 2.5 版，附源码 ) -: multithreading (Multi-Thread) RS232 serial port communication component, the component is COMM32.ZIP modified version, and increase Data Bits, Parity, Stop Bits, such as configuration and support Read/Write timing control (Timing control), ReadIntervalTimeout, WriteIntervalTimout, support DTR/DSR, RTS/CTS hardware flow control and home Xon/software flow control setting home (version 2.5, with source)

The program constructs girth-twelve column-weight QC-LPDC codes. The rate can be changed by changing k(row-weight), size is changed by varying m(sub-matrix size).
