Multitasking operating systems come in two flavors: cooperative multitasking and preemptive multitasking. Linux, like all Unix variants and most modern operating systems, provides preemptive multitasking. In preemptive multitasking, the scheduler decides when a process is to cease running and a new process is to resume running. The act of involuntarily suspending a running process is called preemption. The time a process runs before it is preempted is predetermined, and it is called the timeslice of the process. The timeslice, in effect, gives each runnable process a slice of the processor''s time. Managing the timeslice enables the scheduler to make global scheduling decisions for the system. It also prevents any one process from monopolizing the processor. Bs we shall see, this timeslice is dynamically calculated in the Linux process scheduler to provide some interesting benefits.

多使命操作体系可化分为两类：非抢占式多使命以及抢占式多使命所有像Unix的变种体系以及很多现代操作系同同样，Linux提供抢占式的多使命模式在抢占式多使命模式中，调度步伐决议啥子时候进程中止，新的进程能够开始得到运行这个被强制挂起的动作就叫做抢占进程在被抢占前，运行的时间是预知的，这个时间叫做时间片究竟上，时间片是为每一个运行态的进程分配处置惩罚器的时间的一片管理时间片，使能调度步伐为体系做好整个的局面：胸怀～调度决议时间片也能阻止任何一个进程垄断处置惩罚器正如我们看到的，在Linux进程调度步伐中时间片是蜂蜜面膜动态计算出来的，这样带来很多利益

The Automatic Control Valves ABS is ABS for short, which is based on the conventional brake system security technologies to enhance improved by controlling the brake hydraulic flaps to achieve control of the wheel locking, the braking process , only when the wheels tend to be controlled when locking, ABS will tend to locking of the wheels anti-lock brake pressure regulation; in the control wheel was not tended to locking, the braking Butterfly Valves process and the conventional system exactly the same dynamic system, the braking process, its work process is actually locking - release - Locking - release cycle of the working process, the vehicle is always in the critical state of locking of the roll gap.

而ABS是制动防抱死系统的简称，它是在常规制动装置基础上的加强改进的安全技术，通过控制刹车油压的收放，来达到对车轮抱死的控制，在制动过程中，只有当被控制车轮趋于抱死时，ABS才会对趋于抱死车轮的制动压力进行防抱死调节；在被控制车轮还没有趋于抱死时，制动过程与常规制动系统的制动过程完全相同，其工作过程实际上是抱死—松开—抱死—松开的循环工作过程，使车辆始终处于临界抱死的间隙滚动状态。
