In the past I have defined many Web hosting jargon words that have sent many people to scratching their heads and calling upon the mighty powers of Google to look for an answer. Today I have one more for you. How many times have you hear of somebody saying they needed to FTP something? How about that they need to find a good FTP client? Thankfully FTP is a pretty simple concept to get your mind wrapped around.

在以前的文章中，我曾经解释过一些让普通人难以理解网站设计专业术语，避免了许多人登录Google网站寻找答案。现在，我会再解释一个专业术语：FTP。你是否多次听到别人提到FTP呢？是否听到过他们需要好的FTP客户呢？其实FTP是一个很容易理解的概念。

FTP stands for file transfer protocol. What in the heck is File Transfer Protocol? The easy way to look at it would be to say it is just a way of transferring files over the Internet from one computer to another. Thinking of the Internet as one big network, FTP is the process in which you can get files from one computer to another computer across the globe.

FTP的意思是文件传送协议。那究竟什么是文件传送协议呢？最简单的理解方法就是，FTP是一种通过网络把文件从一台计算机传送到另一台计算机的方法。假设Internet是一个大网络，FTP就是你从另一台计算机中获取文件的过程。

Most of the time that other computer is going to be your Web hosting server, which in itself is a computer.

通常情况下，另一台计算机就是指你的虚拟主机，在本质上说，它就是一台电脑。

Think of it as your Web page files taking a hike across the country in a few seconds. No need to pack the camping gear, get out the toothbrush or even a change of underwear. With the high speed Internet access we have today even larger files can be moved pretty quickly.

假设你的网页文件需要在几秒钟之内传输，这时你不需要整理所有内容，在高速网络传输状态下，我们可以很快完成文件的传送。

FTP came to be way before the time of the Internet we know and love today. It was first used as only a series of text comands to move files from one computer to another over a network. While it hasn't evolved from the main purpose it had, it has "grown up" I guess you could say. Now we use programs such as SmartFTP or CuteFTP to do the work for us.

在网络时代产生之前，FTP就产生了，它首先被用做一连串的文本命令，通过网络，在电脑之间传送文件。现在它并没有改变原来的目的，而是不断发展，你可能会这样说。现在我们利用SmartFTP或者CuteFTP传送文件。

Many of these FTP programs have features on top of features. The only ones you will probably ever use though is the act of connecting to your Web server to upload or download files, documents and folders.

很多FTP程序具有上述特征。你可能经常会利用FTP程序与服务器连接，上传文件、文档、文件夹。
