Of course, $500 is just the starting point for a stripped-down model with a few megabytes of memory.
当然，500美元只是仅有几兆内存的精简型号的起始价。A few megabytes for the binaries , documentation , and configuration files .
二进制代码，文档，和配置文件需要几兆空间。When messages are large ( megabytes rather than kilobytes), memory requirements can be significant.
当消息较大（几兆字节而不是几千字节）时，可能需要较多的内存。Large multi-megabyte documents consisting of thousands of pages are not uncommon in corporate and government circles.
由数千页面组成的几兆字节的大型文档在企业和政府界中并不罕见。Several Japanese groups have already achieved data transmission rates of terabits a second using a small segment of SC spectrum.
利用小区段SC频谱，日本的几个研究小组已经做出每秒几兆位元的资料传输。This can be several megabytes of storage group changes.
可能是几兆字节的存储组发生了更改。We talk now of trillions, not yesterday's hundreds of billions.
我们现在谈论的是几兆的国债，而不是昨天的几百美元。They're asking how can Washington lower the health cost by spending trillions of dollars more over the next ten years?
他们问，未来的十年，华盛顿怎样通过支付几兆美元来降低医疗成本？I do have a problem with my tax dollars going to fund an unnecessary war that is costing us trillions of dollars and costing so many lives.
把我的纳税拿去帮助灾民我绝对没有异议，而把我的纳税拿去资助一个耗资几兆美元，牺牲那么多生命的没有必要的战争，我绝对不会同意！
