我不確定我的回簽對不對喔！請高手指正！ XD ※ 引述《yunruo ()》之銘言： : 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 但是從 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 => 轉16進位 C000 從零開始所以減壹 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的算法應該是7FFF(Hex) : Ans: D : 這題不知怎麼解，懇請高手解答~謝謝 -- ※ 發信站: 批踢踢實業坊(ptt.cc) ◆ From: 114.26.207.60
