Memory Management Solve the following subtasks: a. (11 points) Consider the following scenario: - Let the size of the virtual address space be 8 pages. - Let the size of the physical memory be 4 page frames. - Assume that the physical memory is initially empty. - Let the page replacement algorithm be Least Frequently Used (LRU). - Let the sequence of incoming pages be 5346575175. Sketch the content of the physical memory according to the LRU order after each incoming page. How many page faults will occur? b. (2 points) Consider the following figure: According to the figure, to which physical address is the virtual address 23658810 mapped? Provide the solution as decimal number c. (2 points) How many bytes are wasted due to internal fragmentation when allocating the string Linux in Python? Hint: An empty string requires 49 bytes and each (latin) character requires 1 byte
