查询词典 preemptive multitasking

A preemptive multitasking OS, such as UNIX/Linux, Windows NT/2000 or OS/2, frees up resources when ordered to by the operating system, on a time-slice basis, or a priority basis, so that one application is unable to hog resources when they are needed by another program.

抢先式多任务 OS（例如 UNIX/Linux、Windows NT/2000 或 OS/2）中，操作系统基于时间片或基于优先级命令应用程序释放资源时，应用程序释放资源，以便在其它程序需要资源时，正在使用这些资源的应用程序不会独占它们。
