在执行“LEA BX,BUFFER”指令时,是把( )。
A: BUFFER的内容èBX
B: BUFFER的偏移量èBX
C: BUFFER的段基值èBX
D: BUFFER的内容èEA
A: BUFFER的内容èBX
B: BUFFER的偏移量èBX
C: BUFFER的段基值èBX
D: BUFFER的内容èEA
B
举一反三
- 与LEA AX,BUFFER等价的指令为( )。 A: MOV AX,BUFFER B: MOV AX,OFFSET BUFFER C: MOV AX,DS:BUFFER D: AX EQU BUFFER
- 假设累加器A=556789ABCDh,则指令STH A , -4 , BUFFER执行后BUFFER中的值为 ______ ,指令STL A , 4 , BUFFER执行后BUFFER中的值为______ 。
- () is typically not referred to as a buffer type in critical chain project management. A: Resource buffer B: Free buffer C: Feed buffer D: Project buffer
- 代码: 以下正确的说法是:() A: buffer中所有的元素都具有初始值2。 B: buffer[1]、buffer[2]、buffer[3]的初始值是随机的。 C: buffer[1]、buffer[2]、buffer[3]的初始值是确定的,为0。 D: buffer[1]、buffer[2]、buffer[3]的初始值是确定的,但可能随编译器实现而变化。
- 若COUNTER地址偏移量为0013H,则指令LEA BX,COUNTER;执行后BX=

Which is the correct description of a pinned buffer in the database buffer cache() A: The buffer is currently being accessed. B: The buffer is empty and has not been used. C: The contents of the buffer have changed and must be flushed to the disk by the DBWn process. D: The buffer is a candidate for immediate aging out and its contents are synchronized with the block contents on the disk.
