在通信网络中，接入技术自始至终都是发展的热点。从时分、频分、码分到目前的空分， 从TDMA、CDMA到OFDMA，从单天线到智能天线，先进的技术日新月异，层出不穷。而随着这些新 技术的涌现，WiMAX网络也逐渐成为下一代通信系统的竞争者。很多人认为WiMAX即使无法最终 取代3G，也将是构建未来4G网络的基础，因此很多国际通信设备厂商对于正在兴起的WiMAX寄予 厚望，北电网络甚至放弃了传统3G的研发而专攻WiMAX。 -In the communications network, access technology throughout the development of hot spots. From midnight, frequency division, code assigned to the current air separation, from TDMA, CDMA to OFDMA, from a single antenna to the smart antennas, advanced technology with each passing day, one after another. With the emergence of these new technologies, WiMAX network is becoming the next generation of communication systems competitors. Many people think that WiMAX if not eventually replace 3G, will also be building a foundation for future 4G networks, so many international communications equipment manufacturers who are high hopes for the emergence of WiMAX, Nortel Networks or even to abandon the traditional 3G research and development and specializing in WiMAX.

本教程主要讲述InstallShield开发环境、InstallScript脚本语言基础、基本安装程序的建立、安装界面的设计以及深入安装程序制作等共五章内容。各章内容并不停留在初学者的水平上，而且在制作安装程序的每个方面，都给出了更高、更深层次的方法，例如安装对话框的定制、使用自己的DLL库、操作注册表、安装界面的汉化、使用多媒体、反安装以及安装程序的调试等.-Directory story InstallShield development environment, InstallScript based scripting language, the basic procedures for the establishment of the installation, the installation of interface design and installation of in-depth production process as a total of five chapters. The chapter does not stop at the beginners level, but also in the manufacture and installation procedures for each, are given a higher, more sophisticated methods, such as installing custom dialog box, use the DLL libraries, operate the registry, in line with the installation interface, the use of multimedia, to the installation of anti- the installation and commissioning procedures.

硬盘FAT文件系统原理的详细分析 硬盘由很多盘片(platter)组成，每个盘片的每个面都有一个读写磁头。如果有N个盘片。 就有2N个面，对应2N个磁头(Heads)，从0、1、2开始编号。每个盘片被划分成若干个同心圆磁道(逻辑上的，是不可见的。)每个盘片的划分规则通常是一样的。这样每个盘片的半径均为固定值R的同心圆再逻辑上形成了一个以电机主轴为轴的柱面(Cylinders)，从外至里编号为0、1、2⋯ ⋯ 每个盘片上的每个磁道又被划分为几十个扇区(Sector)，通常的容量是512byte，并按照一定规则编号为1、2、3⋯ ⋯ 形成Cylinders×Heads×Sector个扇区。这三个参数即是硬盘的物理参数。我们下面的很多实践需要深刻理解这三个参数的意义。
