Consider the following statements regarding Paging and Segmentation memory management architectures: I. Paging divides memory into fixed-size hardware-managed blocks called pages and frames, which may result in internal fragmentation within the last page. II. Segmentation uses variable-size units that correspond to the programmer's logical view of memory, such as code, data, and stack segments. III. Paging is known to cause significant external fragmentation because physical frames must be allocated contiguously for each process. IV. While paging is typically invisible to the programmer and based on physical convenience, segmentation is visible to the programmer and organized by logical meaning. Choose the correct option:
