The main memory of a computer system is- Correct Answer Volatile

 RAM অস্থায়ী মেমোরি। কম্পিউটারে যতক্ষণ বিদ্যুৎপ্রবাহ থাকে, ততক্ষণ র‌্যামে তথ্যসমূহ সংরক্ষিত থাকে। বিদ্যুৎপ্রবাহ বন্ধ হওয়া সাথে সাথে র‌্যাম তার সমস্ত তথ্য মুছে ফেলে। এ জন্য র‌্যামকে অস্থায়ী (volatile) মেমোরিও বলা হয়। RAM belongs to main memory.The main memory of a computer system is volatile. ROM মেমোরি non-volatile।(৩৬বিসিএস) আর SRAM, DRAM মেমোরি volatile।(৩৬বিসিএস)

Consider the following two C code segment. Y and X are one- and two-dimensional arrays of size n and n × n respectively, where 2 ≤ n ≤ 10. Assume that in both code segments, elements of y are initialized to 0 and each element X[i] [j] of array X is initialized to i + j. Further assume that when stored in main memory all elements of x are in same main memory page frame. Code segment 1:                 //initialize elements of y to 0                 //initialize elements X[i] [j] of X to i+j                       for (i = 0; i < n; i++)                                 Y[i] += X[0] [i]; Code Segment 2:                 //initialize elements of Y to 0                 //initialize elements X[i] [j] of X to i+j                        for (i = 0; i < n; i++)                                 Y[i] += X[i] [0]; Which of the following statements is/are correct? S1: Final contents of array Y will be same in both code segments S2: Elements of array X accessed inside the for loop shown in code segment 1 are contiguous in main memory S3: Elements of array X accessed inside the for loop shown in code segment 2 are contiguous in main memory

Consider a process executing on an operating system that uses demand paging. The average time for a memory access in the system is M units if the corresponding memory page is available in memory, and D units if the memory access causes a page fault. It has been experimental measured that the average time taken for a memory access in the process is X units. Which one of the following is the correct expression for the page fault rate experienced by the process?
