In the modern era, computers have become an essential part of everyday life for both personal and professional tasks. As technology advances, understanding how computers manage resources is crucial to optimizing their performance. One key aspect of this management is how memory is handled, especially when running multiple or memory-intensive applications. Virtual memory is a fundamental concept that enables efficient memory usage beyond the physical limits of a computer’s RAM. Virtual memory allows computers to compensate for physical memory shortages by temporarily transferring data from RAM to the hard disk….

Paging is one of the most essential concepts in operating systems, forming the backbone of efficient memory management. It allows the operating system to divide both logical memory and physical memory into fixed-size blocks, called pages and frames, respectively. Logical memory pages are mapped to physical memory frames using a data structure called a page table, which helps the OS keep track of the location of each page in main memory. This non-contiguous allocation strategy eliminates the problem of external fragmentation common in contiguous memory allocation systems. Paging ensures that…
