.torrent: A .torrent fille contains all the info you need to download the file you want. For example, a torrent file has info on the size, the filename, and how to connect to other people (tracker). Another important function of the .torrent file is that it has a “hash” (sort of a digital signature) of each part of the file to make sure you don’t download corrupt of fake data but “the real thing”.

Client: The BitTorrent client is the application you use to “load” the .torrent file so that you can connect to other people. There are a lot of different torrent clients available. The three most popular clients are Bitcomet, Azureus and uTorrent. If you’re new to
BitTorrent I would recommend uTorrent, It’s light and has a great settings wizard to help you on your way.

Indexer: Indexers are websites which list (index) .torrent files (myBitTorrent, Torrentz, Mininova etc.).

Leecher: A leecher is someone who is downloading (and uploading) a file. You are a leecher if you do not have a complete copy of the file you’re trying to get. Note that a leecher normally is someone who’s not uploading, that’s not true in the BitTorrent jargon.

Peer: A peer is the same as a leecher, but without the negative connotation.

Ratio: The data you uploaded divided by the data you downloaded. A ratio higher than 1.00 means that you upload more than you download, which is a good thing. Most private trackers keep track of your ratio and will ban or block you if you have a bad ratio. Try to get at least a 1.00 or higher ratio.

Scrape: Scraping means that your BitTorrent client is requesting info from the “tracker” about other people who are down- or uploading the file. This is important because you need to know who has pieces of the file you still need.

Seeder: A seeder is someone who has a complete version of the file you are downloading. If there are no seeders, you probably wont be able to get the file. So seeders are extremely important, make sure to “seed” the torrent once you finished downloading.

Tracker: The tracker is a server that has all the info about the people that are down- and uploading the file. The tracker itself does not have a copy of the file, it only tracks the up- and dowloaders and makes sure people are able to connect to each other. A tracker is not the same as a website that hosts torrents. Mininova for example is not a tracker, just a “torrent-site”.

Super-Seed: Some clients have the option to “super-seed”. Super seeding is different from seeding because it tries to send out pieces of the file that have not been sent before. So instead of sending the same piece to several peers, it tries to send a unique piece to everyone so that other peers can swap those pieces.

Swarm: The swarm are all seeds and peers that are connected together. So if your client shows 5 seeds and 10 peers then that’s your swarm.

Azureus has a plugin to visualize the swarm

Now let’s see if you learned something. If you can understand the next sentence you probably have.

DHT: DHT stands for “Distributed Hash Table”. DHT layers “decentralize” torrents what make them more stable and less reliant on the web based trackers. If a web based tracker goes down, the torrents stay alive because peers can act as “nodes” keeping the swarm intact.

1,首先通过App Store安装Xcode；@import url(http://www.cppblog.com/CuteSoft_Client/CuteEditor/Load.ashx?type=style&file=SyntaxHighlighter.css);@import url(/css/cuteeditor.css);

1、安装手机驱动； 
2、设置PC上的调制解调器属性； 
A, 电脑右键，管理，设备管理，调制解调器； 
B, 设置MODEM属性，高级－额外设置中，添加如下命令： 
cmnet是：AT+CGDCONT=1,"ip","cmnet"  
cmwap是：+CGDCONT=,,"cmwap"
3、cmnet拨号号码是：*99***1# 
   cmwap拨号号码是：*99#

   用户名密码为空

数据线连接PC之后新建internet连接，按上面信息输入，拨号，正常的话成功之后就可以用PC打开网页了

需要引用头文件：#include <afxinet.h>


首先是用ICMP检查网络是否连通：

很简单的几行代码，没有注释；
如果网络不通的话枚举拨号连接，进行拨号：
预先建立拨号连接，以上拨号代码经过修改已经不需要保存密码，只建立一个拨号连接即可。Windows XP or later:  Do not use the RasSetEntryDialParams function. MSDN上面的说法就是RasSetEntryDialParams 别在XP之后的系统上使用了。
检查拨号连接的状态，如果已经通过拨号连接上了网络当然不用再进行拨号了，代码如下：
以上判断是如果检查到有一个已经连接的拨号连接就返回了，应该不会有两个或者以上的拨号连接同时连接，打开端口会失败的。
还有一个是断线：
这个没什么好说的，执行关闭拨号连接的操作。
用程序创建连接，经过修改，已经可以正常创建连接，代码如下：
上面的代码到是可以创建一个拨号连接，不过是个空的，里面没用用户名和密码等信息，需要用上面的拨号代码来指定拨号参数，不能使用RasGetEntryDialParams来获取了。
上面的代码基本上是在网络上搜索所得，稍加修改，在这里整理一下。

再补充一下删除连接的操作,代码如下：
要想实现自动启动拨号网络，就要使用Remote Access Service (RAS) API，这个API最早是在Windows for Workgroup 3.11中出现的，现在它已经成为Win32 API的一个组成部分。该API将整个拨号网络称为Phonebook，而每一个连接称为PhonebookEntry。你可以使用RasCreatePhonebookEntry来创建新的连接，用RasDial来拨号，而RasEnumEntries可以获得当前系统已有的所有连接，使用其它的RAS函数还可以获取或设置连接的参数。 RasEditPhonebookEntry函数将激活标准的Windows 95/NT属性对话框来修改连接的属性。你可以从Win32 API的手册找到所有相关函数的详细介绍。

补充：在windows中一个拨号连接即为一个PhonrbookEntry以下称为电话薄记录或是连接。总的这些称为Phonebook。

int main()
{
int a[5]={1,2,3,4,5};
int *ptr1=(int *)(&a+1);
// a本身就为一个数组的地址，其值=&a[0]，即数组第一个元素的地址，对a再取址
// &a = a，似乎没什么不同，其实这里发生了对齐变更，a+1的对齐是以int为界的
// 而&a+1是以整个数组为单位的，即5个int=20字节，这是关键！！！
// 那么&a+1实际是跨越了整个数组，可得ptr1存储了数组a最后一个元素5紧跟着的一个int的地址

int *ptr2=(int *)((int )a+1);
// 同理，(int)a先将其值（地址）转为整型值，再加一成为一个新的整数
// (int *)将这个值转换为一个指向int型变量的指针（地址）
// ptr2即存储了这个地址和指向的变量的类型

printf("%x,%x",ptr1[-1],*ptr2);
// 先解释一下a[-1]，即将数组向前偏差一个类型大小的距离
// 数组a的内存布局(16进制)：01000000 02000000 03000000 04000000 05000000
// ptr1[-1]
// 你说这里等于什么呢？数组a最后一个元素（5）紧跟着一个int的前面一个元素当然就是5了。
// *ptr2
// ptr2的值为a保存的地址值的绝对值+1，假设a=1000，那么(int)a+1=1001。
// 而后将其再转为(int *)指针，那么指针指向的内存布局为000000 02，即向后移了一个字节
// 那么在little-enddian架构下显示出来为02000000，低位在高地址。
