The operating system queues disk requests when the applications issue them faster than the disks can return the data, optionally reordering them to minimize seeking.
当应用程序发出磁盘请求的速率快于磁盘返回数据的速率时，操作系统会让磁盘请求排队，还可能调整请求的次序以降低寻道时间。
Additional functionality such as column sorting, freezing, and reordering enable users to view data in the way most convenient for their workflow.
其他像是资料行排序、冻结和重新调整顺序的功能，可以让使用者以他们工作流程中最简便的方式检视资料。
