<P>揭开“cookies”之谜</P>
<P>你喜欢cookie(小甜饼)吗?"小甜饼"现在有"大用途"了。 </P>
<P>现在,互联网浏览器储存在电脑里面的文件夹就被称做cookies 。Cookies 是联网用户计算机硬盘中的一个记录用户个人资料、所用电脑系统的资料和该用户浏览过的网页等资料的资料卡。好多网站为了了解有多少人,什么样的人访问本站,要求第一次访问他们的用户输入自己的姓名、地址、电话号码、职业等个人资料,并将这些资料制作成一份访问者资料卡通过访问者的浏览器存储在访问者电脑的硬盘上,起名为cookies.txt。这就等于给初访者发了一张会员卡。当该用户下次重访该网站时,他的电脑浏览器就会自动出示这张会员卡,不必重重验关就可以进入该网站。 </P>
<P>为何要将这种资料卡取名为cookies 没有人能说清楚。有人说cookies 可能源于海外中国餐馆在客人用完餐离开前向客人所赠"幸运小饼干"(fortune cookies)。这种说法不是没有道理,因为掰开每块"幸运小饼干",里面都有一张小字条,印有一句让客人看后开心一笑的警句之类的吉祥话。有的还描绘客人的个性特点,为客人卜算前程。想必这也是个人化的信息吧。 </P>
<P>还有一种说法,认为cookies 成为电脑术语和《艾丽斯奇境历险记》中出现的magic cookie有关系。 Magic cookie可以神奇地使艾丽斯变大或变小,这和新用户登录网站时,电脑中的某一程序就会因cookie记录相关信息而增加容量有共通之处。不过这个类比似乎站不住脚。因为艾丽斯变大后要想再缩回去的话,必须饮用装在写着"DRINK ME"的瓶子里面装的东西或把"白兔扇"握在手里才行,而电脑术语中的cookie对此没有什么对应。可见,小说情节里的magic cookie和电脑术语里的 cookie还不能完全对不上号。 </P>
<P>话说回来,"幸运小饼干"给网上用户带来的未必是好运,因为它窥探用户的隐私,使人如芒刺在背,感到不安。如果你想知道你电脑中的"小饼干"记录了你哪些资料,不妨打开你的电脑硬盘浏览器目录中?"小饼干"文件看一看。</P>

<P>INTERNET WORDS</P>
<P>ADN <BR>(Advanced Digital Network) -- Usually refers to a 56Kbps leased-line. </P>
<P>Applet <BR>A small Java program that can be embedded in an HTML page. Applets differ from full-fledged Java applications in that they are not allowed to access certain resources on the local computer, such as files and serial devices (modems, printers, etc.), and are prohibited from communicating with most other computers across a network. The current rule is that an applet can only make an Internet connection to the computer from which the applet was sent. </P>
<P>Archie <BR>A tool (software) for finding files stored on anonymous FTP sites. You need to know the exact file name or a substring of it. </P>
<P>ARPANet <BR>(Advanced Research Projects Agency Network) -- The precursor to the Internet. Developed in the late 60’s and early 70’s by the US Department of Defense as an experiment in wide-area-networking that would survive a nuclear war. </P>
<P>ASCII <BR>(American Standard Code for Information Interchange) -- This is the de facto world-wide standard for the code numbers used by computers to represent all the upper and lower-case Latin letters, numbers, punctuation, etc. There are 128 standard ASCII codes each of which can be represented by a 7 digit binary number: 0000000 through 1111111. </P>
<P>Backbone <BR>A high-speed line or series of connections that forms a major pathway within a network. The term is relative as a backbone in a small network will likely be much smaller than many non-backbone lines in a large network. </P>
<P>Bandwidth <BR>How much stuff you can send through a connection. Usually measured in bits-per-second. A full page of English text is about 16,000 bits. A fast modem can move about 15,000 bits in one second. Full-motion full-screen video would require roughly 10,000,000 bits-per-second, depending on compression. </P>
<P>Baud <BR>In common usage the baud rate of a modem is how many bits it can send or receive per second. Technically, baud is the number of times per second that the carrier signal shifts value - for example a 1200 bit-per-second modem actually runs at 300 baud, but it moves 4 bits per baud (4 x 300 = 1200 bits per second). </P>
<P>BBS <BR>(Bulletin Board System) -- A computerized meeting and announcement system that allows people to carry on discussions, upload and download files, and make announcements without the people being connected to the computer at the same time. There are many thousands (millions?) of BBS’s around the world, most are very small, running on a single IBM clone PC with 1 or 2 phone lines. Some are very large and the line between a BBS and a system like CompuServe gets crossed at some point, but it is not clearly drawn. </P>
<P>Binhex <BR>(BINary HEXadecimal) -- A method for converting non-text files (non-ASCII) into ASCII. This is needed because Internet e-mail can only handle ASCII. </P>
<P>Bit <BR>(Binary DigIT) -- A single digit number in base-2, in other words, either a 1 or a zero. The smallest unit of computerized data. Bandwidth is usually measured in bits-per-second. </P>
<P>BITNET <BR>(Because It’s Time NETwork (or Because It’s There NETwork)) -- A network of educational sites separate from the Internet, but e-mail is freely exchanged between BITNET and the Internet. Listservs?, the most popular form of e-mail discussion groups, originated on BITNET. BITNET machines are usually mainframes running the VMS operating system, and the network is probably the only international network that is shrinking. </P>
<P>Bps <BR>(Bits-Per-Second) -- A measurement of how fast data is moved from one place to another. A 28.8 modem can move 28,800 bits per second. </P>
<P>Browser <BR>A Client program (software) that is used to look at various kinds of Internet resources. </P>
<P>BTW <BR>(By The Way) -- A shorthand appended to a comment written in an online forum. </P>
<P>Byte <BR>A set of Bits that represent a single character. Usually there are 8 Bits in a Byte, sometimes more, depending on how the measurement is being made. </P>

Page views(综合浏览量):网站各网页被浏览的总次数。一个访客有可能创造十几个甚至更多的PAGEVIEWS。
<P>  Impression(印象):放置广告图像的网页每一次显示, 就是一次印象。 </P>
<P>  Clicks(点击次数):每一次当访客通过点击这个横幅广告访问一次商家网页,称点击一次。点击次数可以客观准确地反映广告效果。</P>
<P>  Clicks Ratio(点击率):是广告吸引力的一个标志。如果这个网页出现了一万次,而网页上的广告的点击次数为五百次,那么点击率即为5%。</P>
<P>  CPM(Cost per Thousand Impressions)网上广告产生每1000个广告印象(显示)数的费用。按访问人次收费已经成为网络广告的惯例。目前国际上每个CPM收费从$20到$80不等。</P>
