The Internet Protocol (IP) is the method or protocol by which data is sent from one computer to another on the Internet. Each computer (known as a host) on the Internet has at least one IP address that uniquely identifies It from all other computers on the Internet. When you send or receive data (for example, an e-mail note or a Web page_, the message gets divided into little chunks called packets. Each of these packets contains both the se nder’s Internet address and the receiver’s address. Any packet is sent first to a gateway computer that understands a small part of the Internet. The gateway computer reads the destination address and forwards the packet to an adjacent gateway that in turn reads the destination address and so forth across the Internet until one gateway recognizes the packet as belonging to a computer within its immediate neighborhood or domain. That gateway then forwards the packet directly to the computer whose address is specified.

IP协议是一个将数据从一个电脑发送到另一个电脑的模型或者协议。所有在英特网中的每台电脑都有一个唯一的IP地址，当你传送或者接受数据时，信息被划分成块，这个块被叫做数据包。每个数据包都包含着源地址和目的地址。每个数据包第一次被送到网关的时候知道了它们是因特网中很小的一部分。在相邻的网关读取目的地址和源数据包依次向前推进直到网关能够识别数据包是属于相邻的域。网关直接读取数据包前向的详细信息。

“E-”or “electronic”marketplace in a business-to-business context is primarily a large online platform(B2B portal) or website that facilitates interactions and/or transactions between buyers and suppliers at organizational or institutional rather than individual levels. Since the builders of such marketplaces primarily aim at facilitating buyer-seller interaction(in most cases without being a buyer or seller themselves), these are also referred to as “third-party” B2B marketplaces. These marketplaces can do one or more of the following:

(1)Help buyers find new supplies and vice versa

(2)Help reduce the time and cost of interaction for B2B transactions

(3)Help increase trade between distant geographies

(4)Help manage payments and track orders for B2B transactions

(5)Help the environment by using appropriate technology that is environmentally friendly

“E”或“电子”市场的企业对企业的环境，主要是一个大型的网上平台（B2B门户网站）或网站，有利于组织或机构，而不是个人层面的买家和供应商之间的相互作用和/或交易。由于建造这种市场的主要目的是促进买卖双方的相互作用（在大多数未知买方或卖方自身的情况下，），它们也被称为“第三方”的商对商市场。

这些市场可以做如下：

（1）帮助买家寻找新的供应和反之亦然

（2）有助于减少互动的时间和成本的B2B交易
