Detailed explanation-1: -Paging is the memory management technique in which secondary memory is divided into fixed-size blocks called pages, and main memory is divided into fixed-size blocks called frames. The Frame has the same size as that of a Page.
Detailed explanation-2: -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-3: -With Paging, Physical memory is broken into fixed-sized blocks called frames.
Detailed explanation-4: -Fragmentation refers to an unwanted problem that occurs in the OS in which a process is unloaded and loaded from memory, and the free memory space gets fragmented. The processes can not be assigned to the memory blocks because of their small size. Thus the memory blocks always stay unused.
Detailed explanation-5: -In the Paging method, the main memory is divided into small fixed-size blocks of physical memory, which is called frames.
