4、Температура колеблется от __________ до __________.
A.20 градуса, 22 градусов
B.20 градуса, 22 градуса
C.20 градусов, 22 градуса
D.20 градусов, 22 градусов
参考答案和解析
A 解析:C7FFFFH-AC000H=1BFFFH,把1BFFFH转换为10进制数得到114687,再化为K,即114687/1024=112K。已知是内存地址按字(16bit)编址,则共有112K×16位。该内存由28片存储器芯片构成,每片有16K个存储单元,则该芯片每个存储单元存储(112K×16)/(28×16K)=4位。
