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。

这是最近做的计算机图形学实验，其界面是一个仿WINDOWS下的窗口界面，程序具有较好的交互性。全部的图形函数都没有用C语言自带的图形库函数，所写的函数都是直接写屏实现的，模拟了大部分图形库函数的功能。但也有部分没有写出，如保存图形块的getimage()等函数。由于水平有限，还有部分功能没有实现，如保存或打开BMP图片等。等有了时间再说吧。算法什么的写的很潦草，都随便说说的，欢迎高手指点，希望与广大C语言爱好者共同学习讨论-This is a recent computer graphics experiment, its interface is an imitation of the Windows interface window, procedures have better interactivity. All of the graphics function in C language with no onboard graphics library functions, functions are written directly to write to achieve the screen to simulate the most graphic library of functionality. However, some are not write, such as the preservation of graphic block getimage () function. Because of the limited level, there is no function for example, the preservation of open or BMP images. With such time until then. What algorithm is written scribble, idle, welcomed the master guiding, and the majority of enthusiasts common C language study and discussion

虽然现在很难想象，有一段时间没有那么久以前…
Although it s kind of hard to imagine now, there was a time not so long ago when the concept of a video game was a "pie in the sky" idea. Computers were barely seen as useful tools in business, and were viewed as having even less potential for entertainment. Technology has a way of changing the way we think about things, and it wasn t long before early video games captured the minds and quarters of an entire generation. Yes, I am a child of the eighties, and I feel fortunate to have spent part of my childhood in the decade where video games went from a pipe dream to a cultural phenomenon.
