Which of the following statements is incorrect about virtual memory? each program has its own address space which is broken into chunks called pages. when a program executes an instruction like MOV REG1, 1000 the address 1000 is generated by the program (using indexing, base registers, or other ways) and is called a virtual address. when virtual addresses are used, they go on the memory bus, and next they enter a memory management unit (MMU), which maps virtual addresses onto physical addresses. the mapping of virtual addresses to physical addresses includes: splitting of the virtual address into a virtual page number (high-order bits) and an offset (low- order bits): this virtual page number is then used as an index into a page table: from the table entry the (physical) page frame number is found
