3、non-the worlds largest garage sale, online shopping center, ear dealer and auction site with 147 million registered users in 30 countries as of March 2005. You can find everything from encyclopedias to olives to snow boots to stereos to airplanes for sale. And if you stumble on it before the eBay ov
4、erseers do, you might even find a human kidney or a virtual date. eBay Basics eBay is, first and foremost, an online auction site. You can browse through categories like Antiques, Boats, Clothing Accessories, Computers Networking, Jewelry Watches and Video Games. When you see something you like, you
5、 click on the auction title and view the details, including pictures, descriptions, payment options and shipping information. If you place a bid on an item, you enter a contractual agreement to buy it if you win the auction. All auctions have minimum starting bids, and some have a reserve price-a se
6、cret minimum amount the seller is willing to accept for the item. If the bidding doesnt reach the reserve price, the seller doesnt have to part with the item. In addition to auctions, you can find tons of fixed-price items on eBay that make shopping there just like shopping at any other online marke
7、tplace. You see what you like, you buy it, you pay for it and you wait for it to arrive at your door. You can pay for an item on eBay using a variety of methods, including money order, cashiers check, cash, personal check and electronic payment services like PayPal and BidPay. Its up to each seller
8、to decide which payment methods hell accept. Just as you can buy almost anything on eBay, you can sell almost anything, too. Using a simple listing process, you can put all of the junk in your basement up for sale to the highest bidder. When you sell an item on eBay, you pay listing fees and turn ov
9、er a percentage of the final sale price to eBay. Once you register (for free) with eBay, you can access all of your eBay buying and selling activities in a single location called “My eBay.“ eBay Infrastructure A series of service disruptions in 1999 caused real problems for eBays business. Over the
10、course of three days, overloaded servers intermittently shut down, meaning users couldnt check auctions, place bids or complete transactions during that period. Buyers, sellers and eBay were, very unhappy, and a complete restructuring of eBays technological architecture followed. In 1999, eBay was o
11、ne massive database server and a few separate systems running the search function. In 2005, eBay is about 200 database servers and 20 search servers. The architecture is a type of grid computing that allows for both error correction and growth. With the exception of the search function, everything a
12、bout eBay can actually run on approximately 50 servers-Web servers, application servers and data-storage systems. Each server has between 6 and 12 microprocessors. These 50 or so servers run separately, but they talk to each other, so everybody knows if there is a problem somewhere, eBay can simply
13、add servers to the grid as the need arises. While the majority of the site can run on 50 servers, eBay has four times that. The 200 servers are housed in sets of 50 in four locations, all in the United States. When youre using eBay, you may be talking to any one of those locations at any time-they a
14、ll store the same data. If one of the systems crashes, there are three others to pick up the slack. When youre on the eBay Web site and you click on a listing for a Persian rug, your com-puter talks to Web servers, which talk to application servers, which pull data from storage servers so you can fi
15、nd out what the latest bid price is and how much time is left in the auction, eBay has local partners in many countries who deliver eBays static data to cut down on download time, and there are monitoring systems in 45 cities around the world that constantly scan for problems in the network. Using e
16、Bay: Security In order to make buyers feel safer when making purchases on eBay, all tangible (有形的 ) items are automatically insured for $200. A recipe that was supposed to be delivered to you via e-mail is not considered a tangible item. But if you purchased a set of speakers that never arrived, and
17、 you go through the dispute process and eBay determines you were defrauded (欺骗 ), you can get your money back up to $200. Buyer Fraud Buyer fraud is typically less damaging than seller fraud. The most common type of fraud a buyer can commit is simply not paying for an item. Sellers can deal with non
18、-paying bidders by filing an Unpaid Item dispute, eBay will then attempt to contact the buyer and get her to pay. If she does not respond to eBays attempts after eight days, the seller is reimbursed (赔偿 )for eBays cut of the final sale price and can relist the item for free. If the buyer does respon
19、d, the dispute can end in one of three ways: The buyer decides to pay, and everybodys happy. The buyer and the seller decide together to abandon the transaction, the seller gets reimbursed for the final-value fee and relists the item for free, and everybodys happy. The seller decides not to deal wit
20、h the buyer, the buyer gets an unpaid-item strike against her, and the seller gets reimbursed for the final-value fee and relists the item for free. In the end, the damage to the seller is relatively small. Another type of buyer fraud occurs when a buyer sends false payment. In most cases, this is i
21、n the form of a bounced check, and the seller finds out about it before shipping the item. Bounced checks are as common on eBay as they are in the rest of the world, and many sellers choose not to accept personal checks for this reason. Seller Fraud Seller fraud is what most people think about when
22、they worry about using eBay. There are two main ways in which a buyer can be defrauded by a seller. The item the buyer purchased is dramatically different from how it was described in the listing; or the item simply never arrives. One thing to keep in mind when you think youve been defrauded is that
23、 miscommunication is common on eBay. For instance, if you didnt read every word of the auction listing for your item, you may have missed the part that said the seller would be out of town for three weeks and wouldnt be able to ship the item until she returned. This could be why you dont have your i
24、tem and the seller isnt answering your e-mails. Also, e-mail is not the most straightforward form of communication. If your item hasnt arrived after two weeks, and youve e-mailed the seller but havent heard back, its a good idea to check your junk mail folder. Your seller may have sent a response e-
25、mail that just never made it to your inbox. If theres nothing from the seller in your junk folder, you can request that eBay reveal your sellers phone number so you can give him a call and see whats going on. If you dont get an answer to your phone call (or if your seller lives in another country an
26、d it would cost too much money to call), your next step is to start the dispute process. When a buyer believes he has been defrauded, he can file a complaint, and eBay will work to solve the problem. When you file a complaint in eBays “Item Not Received or Significantly Not as Described“ system, eBa
27、y will act as middleman between you and your seller to try to settle the dispute. If that fails, you can file a claim to get reimbursed for your purchase. 2 Which of the following may be banned by eBay overseers? （ A） Virtual dates. （ B） Any over-priced products. （ C） Priceless antiques. （ D） Rare a
