Question 1 Which of the following is true about virtual addresses? Virtual addresses for the same physical memory location may differ from process to process Virtual addresses are synonymous with physical addresses Virtual addresses always refer to locations on disk Virtual addresses for the same physical memory location may differ from thread to thread Question 2 How do pages and frames relate to each other? A page holds words while a frame holds pictures A frame is a larger structure than a page that contains a page along with control variables A page is a chunk of virtual memory loaded into a frame of physical memory A page refers to one of many areas of memory simultaneously loaded into a single frame

Answer 1

1. A Virtual Address refers to Primary Memory Address Space that is been allocated to a specified process or processes. It is different from Physical Addresses for devices that support Memory Management Unit functions. The Operating System allows processes to work in physical address locations when required but not always refers to location on disk. It works for individual processes not threads. So option 1 is correct which illustrates that Virtual Memory Address can differ from process to process for same physical memory location.
