These two classes show an extremely simple example of java.net socket programming. They implement the Unix daytime protocol, an extremely simple protocol that consists entirely of the server sending its current local time and date to the client as an ASCII string. The server, to keep it very simple, ...

红外通信是利用950nm近红外波段的红外线作为传递信息的媒体，即通信信道。发送端采用脉时调制（PPM）方式，将二进制数字信号调制成某一频率的脉冲序列，并驱动红外发射管以光脉冲的形式发送出去；接收端将接收到的光脉转换成电信号，再经过放大、滤波等处理后送给解调电路进行解调，还原为二进制数字信号后输出。 ...

SVMmulticlass: Multi-class classification. Learns to predict one of k mutually exclusive classes. This is probably the simplest possible instance of SVMstruct and serves as a tutorial example of how to use the programming interface.

Universal Serial Bus (USB) is a communications architecture that gives a personal computer (PC) the ability to interconnect a variety of devices using a simple four- wire cable. The USB is actually a two-wire serial communication link that runs at either 1.5 or 12 megabits per second (mbs). USB pr ...

Anyone who interacts with today s modern databases needs to know SQL (Structured Query Language), the standard language for generating, manipulating, and retrieving database information.
