集群中所有节点对数据的并发访问，以及某些分布式文件系统所内置的高可用性，是它们成为集群环境理想选择的两方面原因。

Concurrent access to data from all nodes in a cluster and the high availability built into some distributed file systems are a couple of reasons why they are ideal for a cluster environment.

通过将分布式计算资源组合到单一的系统“图像”中，网格计算生成了可以使用户访问所需数据和资源的虚拟机算计。

By combining distributed computing resources into a single system "image," grid computing creates a virtual computer from which users can access data and resources as required.
