《Operating System Concepts》閱讀筆記:p794-p807
《Operating System Concepts》學(xué)習(xí)第 70 天,p794-p807 總結(jié),總計 14 頁。
一、技術(shù)總結(jié)
1.symmetric multiprocessing(SMP)
(1)定義
Multiprocessing in which each processor performs all tasks, including operating-system tasks and user processes. Also, a multiprocessor scheduling method in which each processor is self-scheduling and may run kernel threads or user-level threads.
2.spinlock(自旋鎖)
有時候也稱為 “big kernel lock(BKL)”。
3.File System
(1)extended file system(extfs)
The most common class of Linux file systems, with ext3 and ext4 being the most commonly used file system types.
二、英語總結(jié)(生詞:1)
1.impose
(1)impose: in-("in") + pose("to put, to place")
vt. impose literally means to "to forcefully place sth on sth else"; force sth to be accepted(強制實行,施加)。
注:一般來說,雖然 impose 暗含 forcefully 之意,但翻譯的時候, forcefully 可不用譯出來。
(2)示例
The original implementation of SMP imposed the restriction that only one processor at a time could be executing kernel code.(《Operating System Concepts》第 794 頁)。
上面這句話的意思是:SMP的最初實現(xiàn)施加了一個限制:同一時間只能有一個處理器執(zhí)行內(nèi)核代碼。
