Fragmentation in OS Fragmentation in OS Operating System represents the amount of memory waste during allocation using different Memory Management technique. Fragmentation plays an important role in memory allocation. Methods which produce less fragmentation is considered good for memory allocation. Some time it seems confusing for students to understand the exact difference between internal and […]
Memory Protection in Operating System Memory Protection is an important concept in Operating system. Memory protection in operating system is required to protect the kernel address space from user address space. In order to understand the concept of Memory protection in contiguous memory allocation first, we need to know about the user mode and kernel […]
