25、。自 2022 年 3 月起它已在 30 个国家拥有了 1.47 亿个注册用户。你能在 eBay 上找到一切东西.从百科全书到橄榄、雪地靴、立体音响、到飞机，应有尽有。1如果你在 eBay 监察员插手之前偶然上上 eBay 网，你甚至可能找到一个人的肾脏或一个虚拟约会对象。eBay 基本知识 eBay 首先是一个在线的拍卖站点。你可以通过分类目录浏览古董、小船、服装和装饰品、电脑和互联网类产品、珠宝扣手表以及电子游戏等物品。你看见你喜欢的东西时，你可以点击一下拍卖标题，看看包括产品图片、产品描述、支付选择和送货方式等有关该产品的详细信息。如果你竞标一件物品，赢得拍卖的话。你就可以输入一项合同协

26、议买下第 5页 共 12页它。所有的拍卖品都有一个最低起价，并且有些产品还有一个保留卖方愿意接受的秘密的最低价。2如果投标达不到保留价，卖方就不必出售该商品了。除拍卖之外，你还可以在 eBay 上找到大量价格固定的商品，这使得在eBay 购物就像在其他任何一家在线商场购物一样。你看见你喜欢的东西，买下它，付钱，然后就等货物上门。3对于在 eBay 上买的东西，你可以采用包括汇票、银行支票、现金、个人支票和像 PayPal 和 BidPay 一样的电子支付服务在内的多种付款方式。到底用哪种方式付款取决于各个卖家愿意接受哪种方式。正如你在 eBay 上几乎能买到任何东西一样，你也几乎可以在上面出售

27、任何东西。列张清单，你就可以将你所有放在地下室里不要的东西摆出去竞卖。你在 eBay 出售一样物品时，你得支付挂牌费并且把最后售价的一部分分给eBay。4一旦你注册了(免费)eBay，你就能进入 eBay 网并在一个叫“我的eBay”的单独的地方进行所有的买卖活动了。eBay 的基础设施 1999 年发生的一系列服务混乱使 eBay 的经营出现了实质性的问题。在三天多的时间里，超载的服务器出现间歇关闭，这意味着用户在此期间不能查看拍卖情况，不能投标或完成交易。买方、卖方和 eBay 都非常不开心，因此在那之后 eBay 公司进行了次彻底的技术结构改造。在 1999 年，eBay 是靠一台巨大的

28、数据库服务器和一些单独的系统运行检索功能。到 2022 年，eBay 有了大约 200 台数据库服务器和 20 台检索服务器。eBay 的结构采用一种网格计算体系，可以进行错误修正和升级。除检索功能以外，eBay 的一切操作实际上都能在大约 50 台服务器上运行。这些服务器包括 Web 服务器，应用服务器和数据存储系统。5每台服务器有 6 到 12 个微处理器。这 50 多台服务器是分开运行的，但是他们可以彼此交流，因此如果某个地方出了问题，大家都会知道。需要的时候，eBay 只需给网格增加服务器就行了。当大部分站点都能在 50 台服务器上运行时,eBay 又增加了 3 倍的服务器。第 6页

29、共 12页200 台服务器被分成了四组，每级 50 台服务嚣，各占一个位置。服务器全部都在美国。使用 eBay 时，你可以在任何时候和任何一个位置的服务器进行交流它们存储的数据都是一样的。如果其中一个系统崩溃，还有其他 3 个可以用。6你登陆 eBay 网站，点击一下波斯小地毯的目录，你的电脑便会将信息传达给 Web 服务器，Web 服务器又将信息传达给应用服务器，应用服务器于是从贮存服务器中提出数据，你就可以查到最新的竞标价以及这项拍卖还剩下多少时间。eBay 在很多国家都有负责传送 eBay 的静态数据以减少下载时间的本地合伙人，在全世界 45 个城市还有不断扫描网络问题的监控系统。使用

30、eBay：安全为了使购买者在 eBay 上买东西的时候感到更安全，所有的有形物品都会自动投保 200 美元。7不过通过电子邮件发送给你的一份食谱就不被认为是一件有形物品了。如果你购买了一套扬声器但一直没送到，你可以接通纠纷处理平台，eBay 会确定你是否被欺骗了，如果是，你就可以得回高达 200 美元的保险金。买方欺诈与卖方的欺诈行为相比，买方欺诈通常造成的损失较小。买方最常见的欺诈行为就是买了东西不付栈。8卖方可以通过向 eBay“出价不要纠纷处理平台”提出申请来对付那些不付款的投标者。eBay 会尽量与买方联系让她付钱。如果在 eBay 催款 8 天之后她仍未做出反应.eBay 就会取消收

31、取该商品的最后销售提成以补偿卖方，卖方可以把那件商品免费重新放到商品目录上去。如果买方做出回应，纠纷就会以下列三种方式之一了结：买方决定付钱，皆大欢喜。买方和卖方一同协商后决定放弃交易.卖方通过免交最后销售价提成得到补偿，并将该商品免费重新放到商品目录上，也是皆大欢喜。卖方决定不与买方交易以打击买方的不付款行为，卖方通过免交最后销售价提成得到补偿，并将该商品免费重新放到商品目录上。最后，对卖方造成的损失相对来说就很小了。另一种类型的买方欺诈行为第 7页 共 12页是买方用假支票支付。在大多数情况下，买方使用空头支票会被卖方在寄送商品之前查出来。9空头支票在全世界其他地方随处可见，在 eBay

32、上也是如此。因此很多卖家都选择不接受个人支票付款。卖方欺诈大多数人不放心在 eBay 购物就是因为考虑到卖方可能的欺诈行为。卖方主要以两种方式欺骗买方：买方购买的东西与商品目录上的描述有非常大的差别;或者卖方没有将东西选到买方手中。当你认为你被欺骗了的时候，要注意一件事.即在 eBay 上经常发生交流失误。例如，如果你在拍卖目录里没有详细阅读你要买的商品的每一句描述，你可能就会错过说卖方将外出 3 周，要等她回来才能送货的这部分信息。这可能是为什么你没有收到你买的东西，以及为什么卖方没有回你邮件的原因。此外，电子邮件不是最直接的交流方式。如果你要的东西在两周之后还没到，并且你已经发了电子邮件给

33、卖方，但是没有收到回复，你最好检查一下你的垃圾箱。你的卖方可能回了一封电子邮件给你，但没有被放到你的收件箱。如果你的垃圾箱也没有卖方的任何田复，你就可以要求 eBay 显示卖方的电话号码，你可以打电话给他，看看是怎么回事。如果打电话也没有回音(或者如果你的卖方住在另一个国家。打电话太贵)，你可以进入下一步的纠纷处理。当买方确信自己已经被欺骗时，他可以正式提出投诉.eBay 会对此问题进行处理。当你在 eBay 的“物品未收到或与描述的严重不符”系统提出投诉时，l0eBay 会作为你和你卖方的中间人进行纠纷调解。如果调解失败，你就可以正式提出索赔得到补偿。1.Which of the follo
