我不确定我的回签对不对喔！请高手指正！ XD
※ 引述《yunruo ()》之铭言：
: Suppose there are 4 different memories with the following capacities:
: Memory A: 32K, Memory B: 48K, Memory C: 64K, Memory D: 128K
: All memories start with hexadecimal address (0000)H.
: Which of the following statements is correct?
: A). Memory B can store at most 48000 bytes
1024 * 48 = 49152 Bytes
: B). The highest decimal address in memory D is 131072
1024 * 128 =131072 但是从 0000(Hex)起算，所以是 131071
: C). Memory B can be used to store a byte at address (C300)H
1024 * 48 = 49152 Bytes => 转16进位 C000 从零开始所以减壹 BFFF(Hex)
: D). The highest hexadecimal address for C is (FFFF)H
: E). The highest hexadecimal address for memory A is (7FFE)H
同C的算法 应该是7FFF(Hex)
: Ans: D
: 这题不知怎麽解，恳请高手解答~谢谢
