Description: 功能：
1．在内存中开辟一个虚拟磁盘空间作为文件存储器，在其上实现一个多用户多目录的文件系统。
2．文件物理结构可采用显式链接或其他方法。
3．磁盘空闲空间的管理可选择位示图或其他方法。如果采用位示图来管理文件存储空间，并采用显式链接分配方式，则可以将位示图合并到FAT中。
4．文件目录结构采用多用户多级目录结构，每个目录项包含文件名、物理地址、长度等信息，还可以通过目录项实现对文件的读和写的保护。目录组织方式可以不使用索引结点的方式，但使用索引结点，则难度系数为1.2。
5．设计一个较实用的用户界面，方便用户使用。要求提供以下相关文件操作：
（1）具有login (用户登录)
（2）系统初始化（建文件卷、提供登录模块）
（3）文件的创建： create
（4）文件的打开：open
（5）文件的读：read
（6）文件的写：write
（7）文件关闭：close
（8）删除文件：delete
（9）创建目录（建立子目录）：mkdir
（10）改变当前目录：cd
（11）列出文件目录：dir
（12）退出：logout
-Functions:
1. In memory open up a virtual disk space as a file storage, on its more than a user realize how directory file system.
2. The physical structure can file by explicit links or other methods.
3. Free disk space management can choose a diagrams of or other methods. If using a chart to management and file storage space, and by explicit links distribution methods, it can select a diagrams of merge to FAT.
4. File directory structure using multi-level user directory structure, each directory contains a file name, physical address, length and other information, but also through a catalogue of the file realize read and write protection. Catalogue organization can not use index node way way, but use index node, the difficulty coefficient is 1.2.
5. Design a practical user interface, and user-friendly. Required to provide the following documents operation:
(1) have login (user login)
(2) system initialization (built file roll, and provide login module)

Description: This paper was written within the scope of the author´ s own learning process, during her
studies of computer science and on the basis of her own malware analyses.
It was published in order to offer an introduction to several file infection techniques used by
viruses, showing examples and explaining appropriate countermeasures.
It is aimed at everyone who is interested in the topic of malware and does not require previous knowledge, though a basic understanding of the PE file format, virtual memory management and the Windows OS in general is advantageous.

Description: 本文是一篇关于使用VIRTUAL STRING TREEVIEW（简称VST）控件使用的入门教材。VST是一个免费的虚拟的树形控件，功能与速度都远远高于传统的TREEVIEW，但虽然有英语的帮助文件，但很多人仍然难以入门，而一旦入门，则会发现其相对传统的treeview，要好用很多。这篇文章是本人的学习笔记并经过整理，希望能带领大家入门。-This article is an introductory textbook on VIRTUAL STRING TREEVIEW (referred to as VST) control uses. VST is a free virtual tree control, functionality and speed are much higher than traditional TREEVIEW, English help file, but many people still difficult entry, and once started, you may find the relatively traditional treeview to be easy to use. This article and after finishing my study notes, hoping to lead entry.

Description: 局域网内Win32/Linux虚拟文件系统的通信程序，Linux作为服务端，Windows作为客户端.
当链接之后，Linux的共享目录内的文件可以被下载到windows端一个虚拟盘符上（这个虚拟盘符是映射在C盘新建的一个隐藏文件夹名为CliShareDir），可以操纵客户端上的文件，程序会依据客户端的映射目录上的文件的变化情况（包括新建，删除，编辑保存，重命名等等而更改服务端的相同的文件。使得看起来操作客户端的虚拟目录上的文件就如同操纵服务端的共享目录上的文件一样。）
本程序客户端窗体在一开始连接成功后，会自动隐藏。ALT+A是重新显现该客户端窗体的热键，ALD+D是重新隐藏该客户端窗体的热键。其中A取Appear的用意，D取Disappear的用意。同是在C盘会有一个LinkLog.txt的链接日志文件，该文件会记录程序所做的操作。客户端程序存在一个实时检索虚拟盘符上的文件的专门独立的线程。服务端使用select模式做的轮询响应客户端的请求。 各种路径数据存储大部分采用的是单链表，也有一些函数参数是用的数组。
该程序的缺点：大文件（比如50M以上的）传输和反映会很慢，甚至可能出现程序中断。对于一般的小文件还是没什么问题的-LAN the Win32/Linux virtual file system communication program, Linux as a server, Windows as a client.

Description: 采用Socket和多线程技术，实现一个java Web服务器，加深对HTTP的认识。 新建java项目 webServer 新建java文件 WebServer.java Processor.java 一、HTTP协议的作用原理 WWW是以Internet作为传输媒介的一个应用系统，WWW网上最基本的传输单位是Web网页。WWW的工作基于客户机/服务器计算模型， 由Web 浏览器(客户机)和Web服务器(服务器)构成，两者之间采用超文本传送协议（HTTP）进行通信。HTTP协议是基于TCP/IP协议之上的协议，是 Web浏览器和Web服务器之间的应用层协议，是通用的、无状态的、面向对象的协议。HTTP协议的作用原理包括四个步骤： (1) 连接：Web浏览器与Web服务器建立连接，打开一个称为socket（套接字）的虚拟文件，此文件的建立标志着连接建立成功。 (2) 请求：Web浏览器通过socket向Web服务器提交请求。HTTP的请求一般是GET或POST命令（POST用于FORM参数的传递）。GET命令的格式为： GET 路径/文件名 HTTP/1.0 文件名指出所访问的文件，HTTP/1.0指出Web浏览器使用的HTTP版本。 (3) 应答：Web浏览器提交请求后，通过HTTP协议传送给Web服务器。Web服务器接到后，进行事务处理，处理结果又通过HTTP传回给Web浏览器，从而在Web浏览器上显示出所请求的页面-Socket and uses multi-thread technology to achieve a java Web server, HTTP deepen understanding. New projects webServer java java file WebServer.java Processor.java a new role of the HTTP protocol principle WWW Internet as an application system based on the transmission medium, WWW Internet basic transmission unit is a Web page. The calculation is based on the work of WWW client/server model, the Web browser (client) and Web server (server) structure, using Hypertext Transfer Protocol (HTTP) to communicate between the two. HTTP protocol is the protocol TCP/IP protocol based upon, is an application layer protocol between the Web browser and the Web server, is generic, stateless, object-oriented protocol. Action principle HTTP protocol consists of four steps: (1) connection: Web browser to establish a connection with a Web server, open a virtual file called socket (socket), the establishment of this document marks the connection is established. (2) Request: Web browser through the socket
