The manner in which ticks are counted depends, at its lowest level, on the particular hardware platform on which you're running; however, it is typically incremented through an interrupt.
中断控制器硬件可以将中断发送到任何CPU。
The interrupt controller hardware sends interrupts to any CPU.

Hardware support for virtualization includes introduction of new registers in POWER5 and the design of the interrupt control hardware.
通过将数据库的工作负载复制到单独的站点上，这些特性使服务在发生本地硬件故障或灾难性站点故障时不会中断。
By duplicating the workload of the database to a separate site, these features protect users from production downtime in the event of a local hardware failure or a catastrophic site failure.
最后，使用全系统复制，就不能利用高可用性环境的优势来缩短操作系统升级导致的中断时间或减少毁灭性硬件维护。
Finally, with full system replication, you can't take advantage of the high availability environment to reduce OS upgrade outages, or for less disruptive hardware maintenance.

The three main strategies I would use for interrupt and hardware simulation are.
操作系统会因为一个硬件事件而产生中断(例如出现了一个来自网卡的数据包)，对该事件的处理过程从一个中断开始。
When an operating system is interrupted because of a hardware event (such as the presence of a packet through a network adapter), the processing begins in an interrupt.
请看一个实例，一个合理的假定是UNIX硬件往往在几年的时间失效一次(例如，电力供应中断)，让我们假定3年。
Taking an example, a reasonable assumption is that UNIX hardware tends to fail (for example, the power supply breaks) around once every few years, let's say three.
数据填充可能因为硬件或网络故障而中断。
Data feeds may be interrupted by hardware or network failures.
中断控制器硬件需要确定中断源，以及应该接收该中断的分区。
The interrupt controller hardware needs to recognize the source of the interrupt and which partition should receive that interrupt.
你须要知道一些关于硬件底层中断处理的背景知识。
You do not need to know the low-level background about how hardware interrupts are handled.
设备驱动模式，在设备须要内核关注时，由设备主动发送一个硬件信号(通常是通过一个中断)给内核。
Driven on the device side. The device sends a hardware signal (by generating an interrupt) to the kernel when it needs the kernel's attention.
计算机硬件的核心器件有CPU、内存、中断控制器、DMA控制器，等等。
The essential hardwares of computer contain CPU, memory, interrupt controller, DMA controller, etc.
系统安全——系统安全是指网络系统的硬件、软件及其系统受到保护，系统连续可靠正常地运行，网络服务不中断。
System security is that the hardware, software and system of the network system are protected, and the system runs normally and reliably.
异步中断是由其他硬件设备产生的，可以在CPU时钟信号的任意时刻到来。
Asynchronous interrupts are generated by other hardware devices at arbitrary times with respect to the CPU clock signals.
中断设置与卡中的设置不匹配。请检查硬件设置，然后再试一次。
The interrupt setting does not match those on the card. Check your hardware Settings, and then try again.
系统集成了CTI技术、数据库技术及中断驱动方式控制硬件板卡，具有良好的可扩展性、灵活性、自适应性。
Integrate CTI technology, database and interrupt drive method are used to control hardware and telephone system, so the system is more extendable, flexible and adaptive.
