Description: 用c语言编写串口程序
在当今,流行的编程软件种类繁多，它们编程方便、易于维护，但是在与硬
件直接打交道和编制系统软件时却束手无策，于是C语言就有了用武之地。C语言
作为汇编语言与高级语言之间的一种过渡语言，兼有汇编语言的高效和高级语言
的方便。
在通讯中，为了保证行运安全可靠，标准的串行口必须具有许多握手信号和
状态信息。这是因为通讯的各个计算机CPU速度不一样（这会导致“错帧”）以
及发送机发送数据速度比接收机接收速度快（这会导致“过冲”）。为解决这个
问题，我们采用一个简单的握手信号，即发送机每次仅发送半个字节（低4位）
的数据，而另外半个字节（高4位）则用来传送信息。我们可以对信息位（高4位）
进行如下简单的编码：
0H：发送的是新的半个字节数据
1H：重新发送上次传送错误的数据
2H：文件名结束
3H：文件结束
这样，每当发送机发送一个字节以后，就等待接受机发回送信号，这回送信号就
是发送机发送过来的那个字节。发送机接收到回送信号后，把它与刚发送的字节
相比较，如果相同，就发送新的半个字节，否则就重新发送。新数据与旧数据通
过信息位来区分。下面就是用C语言编写控制串行口的程序。

a USB or a PS2 interface. From that, it will branch either to USB_Main or
PS2_Main.

Description: FAT文件系统原理
计算机在按下power键以后，开始执行主板bios程序。进行完一系列检测和配置以后。开始按bios中设定的系统引导顺序引导系统。假定现在是硬盘。Bios执行完自己的程序后如何把执行权交给硬盘呢。交给硬盘后又执行存储在哪里的程序呢。其实，称为mbr的一段代码起着举足轻重的作用。MBR(master boot record),即主引导记录，有时也称主引导扇区。位于整个硬盘的0柱面0磁头1扇区(可以看作是硬盘的第一个扇区)，bios在执行自己固有的程序以后就会jump到mbr中的第一条指令。将系统的控制权交由mbr来执行。在总共512byte的主引导记录中，MBR的引导程序占了其中的前446个字节(偏移0H~偏移1BDH)，随后的64个字节(偏移1BEH~偏移1FDH)为DPT(Disk PartitionTable，硬盘分区表)，最后的两个字节“55 AA”(偏移1FEH~偏移1FFH)是分区有效结束标志。-FAT file system in principle computer keys after pressing the power to start procedures for the implementation of motherboard bios.

Description: WebZip 是把一个网站下载并压缩到一个单独的 ZIP 文件中，可以帮您将某个网站全部或部份资料以ZIP格式压缩起来，可供你日后快速浏览这个网站。且新一版的功能包括可预定时间来下载，亦加强相当漂亮的立体界面及传输的曲线图。
此版本是直接汉化程序文件，不同于汉化语言文件，汉化较彻底，但仍然有极个别字符没能彻底汉化，但不影响使用。因为是汉化的程序文件，在汉化中对程序界面做了大量优化和美化工作。安装中可选择安装中文版本或英文版本，并可以选择是否注册软件。
