The memory management unit (MMU) maps virtual to physical addresses. When using a single-partition allocation scheme, the main memory is divided into two partitions. The frame table that is applied in systems that use paging is a per-process data structure. Indirect relative addressing refers to an addressing scheme in which the memory address to be accessed is specified explicitly. Segmentation is a memory management approach in which memory areas (segments) allocated to processes are defined by their starting address (base) and length.arrow_forward
- Please help! Please take a look at the code I have provided as a attachment to this question. Please comment each line of code of the differences between program 1 and 2. What happens when you subtract one pointer from another? Is it subtracting the two addresses, or something else? How do you know? What happens when you increment a pointer? Compare and contrast how C-strings are laid out in memory compared to arrays of integers. What's one similarity and one difference? Show how the individual bytes of this integer array are laid out in memory. Thanks!arrow_forwardClarify the meaning of the term "Flow of Compilation and Execution."arrow_forwardTo what do "memory leaks" in dynamic memory allocation refer?arrow_forward
