1.如何查专业术语的意思？
百科全书
http://en.wikipedia.org/wiki/Main_Page
2.如何在一台电脑上用双显示器
最便宜的方法是买块PCI显卡，装上并安装driver，然后desktop->property->setting->
extend desktop。如果要三台或四台显示器的话，PCI插槽够，就买PCI卡，不够买
Matrox
的PCI卡，有一个卡连两台和四台显示器的，很贵。
好像还有一种方法用软件往onboard和AGP卡上传图像的，忘了叫啥。
3.如何用代理上网(隐藏IP)?
目前国内电信把不少网站IP地址都屏蔽了（也就是禁止了大家访问偶们论坛），但只要你
选用了代理服务器上网，你的IP连到的就是代理服务器的IP后再连到偶们论坛，相当于你
转了一圈再到这，这样电信就不能禁止大家访问偶们论坛了.
找到自动代理浏览器，可以为你解决代理上网的问题，下面跟偶一步一步来。
(1).下载自动代理浏览器 TouchNet 1.28a
下载地址：
【 以下看到的所有地址，都要复制到IE的地址栏，然后回车打开 】
http://www2.skycn.com/soft/9003.html
用户名：logroll
注册码：295416435575
或：
用户名：Guhong
注册码：291625486646
(2).用RAR解压下载的压缩文件后如图点自动代理浏览器.EXE安装
(3).安装完成后桌面上出现图标TouchNet Browser打开会提示你注册，用自动代理浏览器
-
帐号里提供的注册码即可
(4).运行TouchNet Browser后点工具选项，下拉菜单里选多代理服务器
(5).再点整理代理服务器
(6).再点更新代理服务器列表，哈哈，出来好多代理啦吧，注意要把启用代理服务器前打
勾。
(7).双击选一个，例如偶选的200.48.218.179：80，再点确定就OK了
(8).到这里看看，ip地址已变为200.48.218.179了，呵呵，成功了
(9).这个浏览器最大的好处是平时你还是可以用IE浏览器正常访问，如果本站被屏蔽不能
访问了，就打开自动代理浏览器选好代理，是不是超级简单好用啊
还有一点要注意的是：
如果这个代理不行，就换其他的，还不行，就再换，反正也非常简单！
并不是任何一个代理都可以打开被屏蔽的网站的。
然后再教大家如何在 IE 中使用代理！
首先要找到代理：
http://www.stayinvisible.com/index.pl/proxy_list
在这个网站，可以看到公布代理的许多网站（比如：http://www.proxy4free.com），有能力注册的朋友可以注册，从而使用该网站提供的验证代理有效性的功能。一般新公布的代理都是有效的！
http://www.proxyabc.com
这个网站可以直接按照国家过滤代理，我一般都用美国或加拿大的。
这个也不错！
http://www.proxy4free.com
得到代理了，然后：
打开IE浏览器，点工具－Internet选项－连接－局域网设置，在"代理服务器"的那个框
框里，把两个小方块儿里都打上勾，然后在地址里填上"64.71.148.68"，端口里填上"
80"，然后一路确定就可以了！
浏览完H网后，再想看其他网站，比如"P网"，只要把第一个勾去掉即可！！
再给大家推荐几个公布代理的网站：（请把下列地址复制到IE的地址栏，回车！）
http://www.stayinvisible.com/index.pl/proxy_list
http://www.proxy4free.com/page1.html
http://www.publicproxyservers.com/page1.html

4.什么是VPN？
A virtual private network (VPN) is a private data network that makes use of
the public telecommunication infrastructure, maintaining privacy through the
use of a tunneling protocol and security procedures. The idea of the VPN is
to
give the company the same capabilities at much lower cost by using the
shared
public infrastructure rather than a private one.
一般学校公司都用VPN，保护学校的library的信息，公司的信息。你要登陆学校和公司的
VPN，然后才能访问你在学校和公司的机器。即使你要访问的机器是WAN的IP。
5.How to setup FTP server on Windows XP Pro
a.enable IIS
control panel --> add or remove programs -->add or remove windows
components
-- choose IIS and expand subtree choose FTP
b.disable your firewall on server pc
c.set up passwd and username
d.use IE visit FTP you may need to open permission to anonymous visit,
otherwise use any FTP client.
file is located under C:\Inetpub\ftproot\
6.Windows底下常用的命令
msconfig
disable the service and auto startup program
ipconfig /all [/release|/renew]
get IP address
regedit
delete some virus register entry
7.比较流行的BT软件
BitComet
edonkey
emule
bearshare
bitlord
8.BT时应注意的事项
不要用DHT选项。
什么是DHT呢？
DHT(Distributed Hash Table), 简单一点的说，当你下一部没有经过压制的电影，电脑
里的软件就会给这部电影生成唯一的DHT，软件把这个DHT汇报给server，当别人用不同
的
种子下同一部电影，并且他的种子死掉了，软件就会到server的DHT找到你的种子接着下
。不同的电脑对于同一部电影将生成一样的DHT，就跟指纹一样。所以发种子要压制，下
载不要用DHT，RIAA(Record Industry American Association)就找不到你。
9.在电脑里如何播放DVD？
要装DVD decoder，然后在Windows media Player or Realone player里放
PowerDVD (non-free)
InterVideo WinDVD (non-free)
K-lite (free)
Divx (free)
10.What do all these words mean in BT? (seeding, uploading, share rating,
etc.
)
Here is a brief list of words associated with BitTorrent and their meanings.
torrent
Usually this refers to the small metadata file you receive from the web
server
(the one that ends in .torrent.) Metadata here means that the file contains
information about the data you want to download, not the data itself. This
is
what is sent to your computer when you click on a download link on a website
.
You can also save the torrent file to your local system, and then click on
it
to open the BitTorrent download. This is useful if you want to be able to re
-
open the torrent later on without having to find the link again.
In some uses, it can also refer to everything associated with a certain file
available with BitTorrent. For example, someone might say "I downloaded that
torrent" or "that server has a lot of good torrents", meaning there are lots
of good files available via BitTorrent on that server.
peer
A peer is another computer on the internet that you connect to and transfer
data. Generally a peer does not have the complete file, otherwise it would
be
called a seed. Some people also refer to peers as leeches, to distinguish
them
from those generous folks who have completed their download and continue to
leave the client running and act as a seed.
seed
A computer that has a complete copy of a certain torrent. Once your client
finishes downloading, it will remain open until you click the Finish button
(
or otherwise close it.) This is known as being a seed or seeding. You can
also
start a BT client with a complete file, and once BT has checked the file it
will connect and seed the file to others. Generally, it's considered good
manners to continue seeding a file after you have finished downloading, to
help out others. Also, when a new torrent is posted to a tracker, someone
must
seed it in order for it to be available to others. Remember, the tracker
doesn't know anything of the actual contents of a file, so it's important to
follow through and seed a file if you upload the torrent to a tracker.
reseed
When there are zero seeds for a given torrent (and not enough peers to have
a
distributed copy), then eventually all the peers will get stuck with an
incomplete file, since no one in the swarm has the missing pieces. When this
happens, someone with a complete file (a seed) must connect to the swarm so
that those missing pieces can be transferred. This is called reseeding.
Usually a request for a reseed comes with an implicit promise that the
requester will leave his or her client open for some time period after
finishing (to add longevity to the torrent) in return for the kind soul
reseeding the file.
swarm
The group of machines that are collectively connected for a particular file.
For example, if you start a BitTorrent client and it tells you that you're
connected to 10 peers and 3 seeds, then the swarm consists of you and those
13
other people.
tracker
A server on the Internet that acts to coordinate the action of BitTorrent
clients. When you open a torrent, your machine contacts the tracker and asks
for a list of peers to contact. Periodically throughout the transfer, your
machine will check in with the tracker, telling it how much you've
downloaded
and uploaded, how much you have left before finishing, and the state you're
in
(starting, finished download, stopping.) If a tracker is down and you try
to
open a torrent, you will be unable to connect. If a tracker goes down during
a
torrent (i.e., you have already connected at some point and are already
talking to peers), you will be able to continue transferring with those
peers,
but no new peers will be able to contact you. Often tracker errors are
temporary, so the best thing to do is just wait and leave the client open to
continue trying.
downloading
Receiving data FROM another computer.
uploading
Sending data TO another computer.
share rating
If you are using the experimental client with the stats-patch, you will see
a
share rating displayed on the GUI panel. This is simply the ratio of your
amount uploaded divided by your amount downloaded. The amounts used are for
the current session only, not over the history of the file. If you achieve a
share ratio of 1.0, that would mean you've uploaded as much as you've
downloaded. The higher the number, the more you have contributed. If you see
a
share ratio of "oo", this means infinity, which will happen if you open a
BT
client with a complete file (i.e., you seed the file.) In this case you
download nothing since you have the full file, and so anything you send will
cause the ratio to reach infinity. Note: The share rating is just a number
that is displayed for your convenience. It does not directly affect any
aspect
of the client at all. In general, out of courtesy to others you should
strive
to keep this ratio as high as possible, of course.
distributed copies
In some versions of the client, you will see the text "Connected to n seeds;
also seeing n.nnn distributed copies." A seed is a machine with the complete
file. However, the swarm can collectively have a complete copy (or copies)
of
the file, and that is what this is telling you. Referring again to the "
people
at a table" analogy, consider the case where the book has 10 pages, and
person A has pp.1-5 and B has pp.6-10. Collectively, A and B have a complete
copy of the book, even though no one person has the whole thing. In other
words, even if there are no seeds, as long as there is at least one
distributed copy of the file everyone can eventually get a complete file.
Meditate on this, the Zen of BitTorrent, grasshopper.
choked
This is a term used in the description of the BitTorrent protocol. It refers
to the state of an uploader, i.e. the thread that sends data to another peer
.
When a connection is choked, it means that the transmitter doesn't currently
want to send anything on that link. A BT client signals that it's choked to
other clients for a number of reasons, but the most common is that by
default
a client will only maintain --max_uploads active simultaneous uploads, the
rest will be marked choked. (The default value is 4 and this is the same
setting that experimental client GUI lets you adjust.) A connection can also
be choked for other reasons, for example a peer downloading from a seed will
mark his connection as choked since the seed is not interested in receiving
anything. Note that since each connection is bidirectional and symmetrical,
there are two choked flags for each connection, one for each Tx endpoint.
interested
Another term used in the protocol specification. This is the corollary to
the
choked flag, in that interested refers to the state of a downloader with
respect to a connection. A downloader is marked as interested if the other
end
of the link has any pieces that the client wants, otherwise the connection
is
marked as not interested.
snubbed
If the client has not received anything after a certain period (default: 60
seconds), it marks a connection as snubbed, in that the peer on the other
end
has chosen not to send in a while. See the definition of choked for reasons
why an uploader might mark a connection as choked. The real function of
keeping track of this variable is to improve download speeds. Occasionally
the
client will find itself in a state where even though it is connected to
many
peers, it is choked by all of them. The client uses the snubbed flag in an
attempt to prevent this situation. It notes that a peer with whom it would
like to trade pieces with has not sent anything in a while, and rather than
leaving it up to the optimistic choking to eventuall select that peer, it
instead reserves one of its upload slots for sending to that peer. (
Reference)
optimistic unchoking
Periodically, the client shakes up the list of uploaders and tries sending
on
different connections that were previously choked, and choking the
connections
it was just using. You can observe this action every 10 or 20 seconds or so
,
by watching the "Advanced" panel of one of the experimental clients.
