※ 引述《wsx02 ()》之銘言：
: 1. consider hardware and software interrupts.
: Suppose X is for Y and triggered by Z. Which of (X,Y,Z) is correct?
: (A) hardware interrupt, to issue I/O request, device controller
: (B) hardware interrupt, to signal I/O completion, device controller
: (C) hardware interrupt, to issue I/O request, device driver
: (D) software interrupt, to request OS services, device driver
: (E) software interrupt, to signal I/O completion, application program
不好意思!想借問一下(A),(B)的issue,signal差在哪?
謝謝
