  • Paging

    ,

    Paging is a memory management technique in operating systems where memory is divided into fixed-sized blocks called pages. Correspondingly, physical memory is divided into frames of the same size. Paging is a memory management scheme that eliminates the need for contiguous memory allocation, dividing physical memory into fixed-sized blocks called frames and logical memory into…

  • Memory Management

    ,

    Memory management is a core function of the operating system responsible for the allocation, deallocation, and optimization of primary memory (RAM). It ensures that processes have sufficient memory to execute while maximizing system efficiency and stability. Memory Management refers to the process by which an operating system manages computer memory, allocating it to processes and…

  • Virtual Memory

    ,

    Virtual memory is a memory management technique that allows the execution of processes that may not be completely in the main memory (RAM). It creates an illusion for users that there is almost unlimited memory by using both hardware and software to map logical addresses to physical addresses. The operating system divides virtual memory into…
