Question
Suppose a virtual memory system has 8 virtual pages, 4 frames, 16 bytes in each frame. Then the number of bits required for each page number is: _____. Suppose a virtual memory system has 8 virtual pages, 4 frames, 16 bytes in each frame. Then the number of bits required for each virtual address is: _____. The regular expression [-d] refers to: A. a digit (0 - 9) B. everything but a digit (0 - 9) C. anything but a d D. anchor to start of a line E. anchor to end of a line Write the smallest length expression that matches: a * b?[cd]x + y Suppose a page table indicates page 3 corresponds to frame 4. Suppose each frame is size 4 bytes. The translation of the page offset will be: _____. Consider a hard disk with 4 one-sided platters, each with 10 concentric circles of data on it, with each circle divided into 5 sections. Then the number of cylinders is: _____. Consider a hard disk with 4 one-sided platters, each with 10 concentric circles of data on it, with each circle divided into 5 sections.
Explanation / Answer
3) The regular expression [~d] refer to
b) everything but a digital (0-9)
In the above we can see that the regular expression [~d] refer to Everything but a digital (0-9)
