Segmentation in Operating System
Segmentation is one of the several memory management techniques adopted by operating systems to accomplish the concept of virtual memory. In our previous content, we have discussed other memory management techniques i.e., paging. Paging is close to the operating system’s view of memory. But the segmentation technique has the user’s view of memory. With segmentation, […]
Paging in Operating System
Paging in operating system is a memory management technique that allows the system to allot non-contiguous physical address space to a process. The concept the paging resolves the problem of external fragmentation that occurs due to the continuous allocation of physical address space to processes. Because of external fragmentation, though enough memory is available to […]
Virtual Memory in Operating System
Virtual memory in operating system is a memory management technique that enables secondary memory to be a part of the main memory. It enables main memory to accommodate large processes even if it is not big enough to accommodate them at once. It improves the performance of the system and helps in implementing a multi-programming […]
Diversity Reception and its Types
