T9901请你翻译答案
带 宽
计算机网络在单位时间内能够传输的数据量称为网络的带宽，通常用每秒千比特数(Kbps)或每秒兆比特数(Mbps)计算。一个比特是计算机能处理的最小信息单元，它可以是0或1。在路由器之间的信息传送通常使用专用通讯线路，目前的传输速率范围从64Kbps到几百Mbps。
信息在因特网上传输的速率，取决于传输路径上最低的传输能力以及在任意给定时间内使用该传输路径的人数。传输路径上带宽狭窄的部分成为数据传输的瓶颈，而且使用线路的人越多，在同一时间里，其中的每一个人能传输的信息就越少。

T9902请你翻译题目：
Digital Cash
Digital cash is a system of purchasing cash credits in relatively
small amounts, storing the credits in your computer or on a smart card, and then spending
them when making electronic purchases over the Internet. Theoretically, digital cash could
be spent in very small increments, such as tenths of a cent (U.S.) or less. Most merchants
accepting digital cash so far, however, use it as an alternative to other forms of payment
for somewhat higher price purchases. DigiCash offers “eCash." Here's how it works:
The consumer or merchant signs up with one of the participating banks. After that you
receive “purse" software to install. The software allows you to download “electronic
coins" to your hard disk. The purse manages your coins. The inital purchase of coins
is charged against your bank account or against a credit card. When you buy something at a
Web store that accepts eCash, you simply click the “Pay with eCash" button. The
store's software generates a payment request, describing the merchandise, price, and the
time and date. You can then accept or reject this request. When you accept, your purse
software subtracts the payment amount from your “purse," and creates a payment that
is sent to the bank, verified, and then deposited to the merchant's account, all within a
few seconds. The merchant is notified and ships the goods.
