操作系统概念术语
我正在为我的班级做一些样本考试的填空，我希望你能仔细检查我的术语。
- 操作系统使用的各种调度队列将由进程列表组成。
- 中断处理是一种定期检查是否满足条件（例如完成某些请求的 I/O 操作）的技术。
- 当 CPU 处于内核模式时，正在运行的程序可以访问一组受限的 CPU 功能。
- CPU 调度程序的工作是在就绪队列中选择一个进程并更改其状态。
- CPU 通常支持中断向量，因此当硬件中发生某些感兴趣的事件时，操作系统可以做出适当的响应。
- 使用陷阱，设备控制器可以利用总线上的空闲时间来读取或写入主存储器。
- 在上下文切换期间，从CPU复制并保存一个进程的状态，并恢复另一进程的状态。
- 操作系统由内核和一组应用程序组成，这些程序作为用户进程运行，为用户提供操作系统服务或在后台工作以保持计算机平稳运行。
我们的章节中有很多术语，我不太确定我是否使用了正确的术语。
I'm doing some fill in the blanks from a sample exam for my class and I was hoping you could double check my terminology.
- The various scheduling queues used by the operating system would consist of lists of processes.
- Interrupt handling is the technique of periodically checking to see if a condition (such as completion of some requested I/O operation) has been met.
- When the CPU is in kernel mode, a running program has access to a restricted set of CPU functionality.
- The job of the CPU scheduler is to select a process on the ready queue and change its state.
- The CPU normally supports a vector of interrupts so the OS can respond appropriately when some event of interest occurs in the hardware.
- Using traps, a device controller can use idle time on the bus to read from or write to main memory.
- During a context switch, the state of one process is copied from the CPU and saved, and the state of a different process is restored.
- An operating system consists of a kernel and a collection of application programs that run as user processes and either provide OS services to the user or work in the background to keep the computer running smooth.
There are so many terms from our chapters, I am not quite sure if I am using the correct ones.

我的想法：
1. 进程和/或线程。工作和任务也并非闻所未闻。可能还有其他事情。例如，在 MS Windows 中，也有可以排队的延迟过程调用 (DPC)。
2. 这必须是轮询。
4. 为什么要使用CPU调度器？为什么不只是调度程序？
6. 我不确定硬件/总线上下文中的陷阱。
My thoughts:
1. Processes and/or threads. Jobs and tasks aren't unheard of either. There can be other things. E.g. in MS Windows there are also Deferred Procedure Calls (DPCs) that can be queued.
2. This must be polling.
4. Why CPU scheduler? Why not just scheduler?
6. I'm not sure about traps in the hardware/bus context.
