[資工研究所]可否幫忙解讀一篇原文~~~

不要用翻譯軟體~~

可否翻譯下面解答!?

Answer:An interrupt is a hardware-generated change-of-flow within the system. An interrupt handler is summoned to deal with the cause of the interrupt; control is then returned to the interrupted context and instruction. A trap is a software-generated interrupt. An interrupt can be used to signal the completion of an I/O to obviate the need for device polling. A trap can be used to call operating system routines or to catch arithmetic errors.

========================================================

Answer:One class of services provided by an operating system is to enforce protection between different processes running concurrently in the system. Processes are allowed to access only thosememory locations that are associated with their address spaces. Also, processes are not allowed to corrupt files associated with other users. A process is also not allowed to access devices directly without operating system intervention.The second class of services provided by an operating system is to provide new functionality that is not supported directly by the underlying hardware. Virtual memory and file systems are two such examples of new services provided by an operating system.

========================================================

Answer:The system is easy to debug, and security problems are easy to solve. Virtual machines also provide a good platform for operating system research sincemany different operating systemsmay run on one physical system.

    Answer:An 中斷hardware-generated 改變流動在系統之內。中斷經理被召喚對成交以中斷的起因; 控制然後返回到被中斷的上下文和指示。陷井是一個軟體引起的中斷。中斷可能使用發信號I/O 的完成消除對設備投票的需要。陷井可能被使用叫作業系統慣例或發現算術錯誤。

    ========================================================

    Answer:One 服務種類由一個作業系統提供將強制執行保護在不同的過程之間一致地運行在系統。過程被允許訪問唯一同他們的地址空間聯繫在一起的thosememory 地點。並且, 過程不被允許對訛誤文件與相關其它用戶。過程也不被允許訪問設備直接地沒有作業系統intervention.The 第二服務種類由一個作業系統提供將提供直接地由部下的硬體不支持的新功能。虛擬記憶體和文件系統是新服務二個這樣例子由一個作業系統提供。

    ========================================================

    Answer:The 系統容易調試, 並且安全問題容易解決。虛擬機為作業系統研究sincemany 另外經營的systemsmay 奔跑並且提供一個好平臺在一個物理系統。
