※ 引述《larryfeng (ㄚ峰)》之铭言： : 1. Which of the following is not a graphic device? : (a) Card reader : (b) Trackball : (c) Joystick : (d) Digitizer table (这种题目是背诵题吗？) : ans: (a) (如果没有背过的话，可以做判断吗？) 这种题目算是考...你看的东西多不多而已 不过graphic device 是绘图装置 所以Card reader应该就很明显了 : 2. Which of the following is not an interrupt? : (a) Power on : (b) Reset : (c) Overflow : (d) OS trap (答案我晓得，只是想请问 OS trap 是什麽意思？) 微软的经典对话框 什麽程式即将关闭blah blah blah... 应该算是OS trap? : 3. For the following items, which one is unnecessary when designing a number : format? : (a) CPU types : (b) Data types : (c) Number of registers : (d) Addressing modes (不懂题目真的的意思 无法作答@@) : ANS:(C) 何者不是设计number format的必要条件 : 4. If the macro : #define RECTANGLE_AREA ( x,y )( (x) * (y) ) : has been defined. Then the line : rectArea = RECTANGLE_AREA (a+4,b+7); will be expanded to : (1) rectArea = 11; : (2) rectArea = (a+4*b+7); : (3) rectArea = ( (a+4)*(b+7) ); : (4) RECTANGLE_AREA ( a+4, b+7 ); : ANS:(2) (可是我怎麽觉得是 3 ？) (3)吧 因为题目是给(x) * (y) 不是 x*y : 5. Which date structure is most suitable for implementing Priority Queue? : (a) queue : (b) stack : (c) linked list : (d) heap : ans:(d) (请问一下答案为D的理由是？) priority queue 是从当中取出priority最高的资料 所以用heap.heap 未指明就是说max heap, 每次均可由heap得到priority最高的一笔资料. : 6. Consider an 8-bit binary number with the following bit pattern: : 10101110 : (a)What is the decimal number if the bit pattern represents a floating number of : the following formal :SEEEMMMM ( S:sing E:exponent M:mantissa ). "The sign is 0 for 6." ^^^^^^^^^^^^^^^^^^^^^^ ??? 你题目可能打太长了,我猜有内容被截掉. : (b)What are the maximal and the minimal positive numbers that can be : represented by this format? : (理念没有学过，不知道该如何下手？) : (如同上次的 IEEE754 一样，希望可以教教我) (a) 1 010 1110 = (-1)^1 * 2^(-2) * 0.1110 = -0.00111(2) S EEE MMMM S E M ^代表二进位 请自行转成十进位 (b) maximal positive numbers = 2^3*0.1111 = 111.1 = 7.5 minimal ....=2^(-4)*0.1111 = 0.00001111 =(请自行转换) 有错请指教~感恩! -- 这流浪的人，努力让梦成真。 That's the way I live, that's the way I did. --
