  1.A handheld’s constraints(局限 性 ) mean that it’s usually impossible to directly port a desktop application to a wireless handheld device. For the same reasons, it’s difficult to directly access most Web sites with a handheld device. Web applications are traditionally designed based on the assumption that visitors will have a desktop computer with a large screen and a mouse. 手持设备的局限性意味着它通 常不能直接把台式应用程序移 植到无线手持设备上,出于同样 的理由,用手持设备直接访问多 数 Web 站点也很困难。 Web 应用 程序传统上是基于访问者拥有 带大屏幕和鼠标的台式计算机 这样的假设而设计的。
  2.A new concept called the Storage Area Network(SAN)(存 储 区 域 网 络 ) could offer an answer to the increasing amount of data that needs to be stored in an enterprise network environment. By implementing a SAN, users can offload storage traffic from daily network operations while establishing a direct connection between storage elements and servers. 对需要在企业网络环境中存储 数据量越来越大的问题,一种称 之为存储区域网络(SAN)的新概 念可能提供了一个答案。通过实 现一个 SAN, 用户可以在存储设 备与服务器之间建立直接连接 的同时,把存储传输负荷从日常 网络操作中分出来。
  3. A Storage Area Network (SAN, 存储区域网) does not need to be a physically separate network, either. It can be a dedicated sub-network, carrying only the business-critical I/O traffic between servers and storage devices. A SAN, for example, would not carry general-purpose traffic such as e-mail or other end-user applications. This type of net avoids the unacceptable trade-offs inherent in a single network for all applications. SAN 不需要在物理上是一个单 独的网络。它可以是一个专用的 子网,只在服务器与存储设备之 间传输关键业务 I/O 信息。 例如, SAN 不传送通用意义上的信息, 如电子邮件或其它最终用户应 用程序。这类网络避免了单一网 络中固有的不能接受的拆衷
