Wi-fi

Wi-fi(发音:/ˈwaɪfaɪ/,法语发音:/wifi/),在中文里又称作“移动热点”,是Wi-fi联盟制造商的商标作为产品的品牌认证,是一个创建于IEEE802.11标准的无线局域网技术。基于两套系统的密切相关,也常有人把Wi-fi当做IEEE802.11标准的同义术语。“Wi-fi”常被写成“WiFi”或“Wifi”,但是它们并没有被Wi-fi联盟认可。

  • 在各种不同的网络传送协议上

    在各种不同的网络传送协议上,为网络编程提供一个大家都很熟悉的接口,需注意各种网络协议的一些特征。本章将全面讲述使用特定协议时应该留意的一些特征,其中包括一些基本的网络连接原理。另外,我们还将讨论如何通过程序向 Wi n s o c k查询协议信息,并探讨针对一种具体协议创建套接字所需的基本步骤。

  • 哈夫曼树又称最优二叉树

    哈夫曼树又称最优二叉树,是一种带权路径长度最短的二叉树。所谓树的带权路径长度,就是树中所有的叶结点的权值乘上其到根结点的路径长度(若根结点为0层,叶结点到根结点的路径长度为叶结点的层数)。树的带权路径长度记为WPL=(W1*L1+W2*L2+W3*L3+...+Wn*Ln),N个权值Wi(i=1,2,...n)构成一棵有N个叶结点的二叉树,相应的叶结点的路径长度为Li(i=1,2,...n)。可以证明哈夫曼树的WPL是最小的。

    QuickSteps books are recipe books for computer users. They answer the question 揌ow do I...??by providing a quick set of steps to accomplish the most common tasks with a particular program. The sets of steps are the central focus of the book. Sidebar QuickSteps provide information on how to do quickly many small functions or tasks that are in support of the primary functions. Sidebar QuickFacts supply information that you need to know about a subject. Notes, Tips, and Cautions augment the steps, but they are presented in a separate column to not interrupt the fl ow. Brief introductions are present, but there is minimal narrative otherwise. Many illustrations and fi gures, a number with callouts, are also included where they support the steps.

  • In this work an implementation of a geometric nonlinear controller for chaos synchronization in a Fi

    In this work an implementation of a geometric nonlinear controller for chaos synchronization in a Field Programmable Gate Array (FPGA) is presented. The Lorenz chaotic system is used to show the implementation of chaos synchronization via nonlinear controller implemented in a Xilinx FPGA Virtex-II 2v2000ft896-4. The main idea is to design a nonlinear geometric controller which synchronizes a slave Lorenz system to a master system and then implement them into the FPGA.
