The AsyncIO sample (also called the "PDC" sample) is a character-mode program for searching the files in a directory tree for a match against a pattern. It uses multiple threads, with each thread processing one file at a time, accumulating its matches. When each thread finishes searching a file, the thread sends the matches contiguously to a standard output.

天线是由韦伯斯特的字典定义作为"通常是金属设备 （比如杆或线) 发射或接收无线电波。"IEEE 标准定义的 天线 （IEEE Std 145 – 1983） ∗ 的术语定义的天线作为"一种手段发射或接收无线电波"。换句话说，天线是过渡自由空间与引导的设备，如图 1.1 所示的结构。指导设备或线路可能采取同轴线或空心管的形式 （导），它用来运输从发射的电磁能量源到天线，或从到接收器天线。在前一种情况，我们有发射天线和后者的接收天线。
