Detailed explanation-1: -Internal fragmentation occurs when we split the physical memory into contiguous mounted-sized blocks and allocate memory for a process that can be larger than the memory requested.
Detailed explanation-2: -The basic idea behind paging is to divide physical memory into a number of equal sized blocks called frames, and to divide a programs logical memory space into blocks of the same size called pages. Any page ( from any process ) can be placed into any available frame.
Detailed explanation-3: -Paging is a method of memory management. External Fragmentation is removed using the concept of paging. The process is divided into ‘Pages’, and the Main Memory is divided into ‘Frames’ so that a part of the process (a page) can be contained in a frame (part of the main memory).
Detailed explanation-4: -In the Paging method, the main memory is divided into small fixed-size blocks of physical memory, which is called frames.
Detailed explanation-5: -Internal Fragmentation In this fragmentation, the process is allocated a memory block of size more than the size of that process. Due to this some part of the memory is left unused and this cause internal fragmentation.
