Paging technique is used for effective management of?

The correct answer is RAM.

Key Points

• Paging is a memory management technique used by operating systems to efficiently utilize RAM.
  • In paging, the physical memory (RAM) is divided into fixed-size blocks called frames.
  • Similarly, the logical memory (virtual memory) is divided into blocks of the same size called pages.
  • When a program is executed, its pages are loaded into available frames in RAM.
  • Paging ensures that the operating system can manage memory efficiently by allowing programs to use non-contiguous memory locations.
  • It also helps prevent memory fragmentation and optimizes the use of limited RAM resources.

Additional Information

• Paging allows processes to execute even if they are larger than the available physical memory, by utilizing virtual memory.
• The operating system uses a page table to keep track of the mapping between pages and frames.
• When a program accesses memory that is not currently in RAM, a page fault occurs, prompting the operating system to load the required page from the disk.
• Paging improves multitasking capabilities, enabling multiple processes to run simultaneously without interference.
• Modern operating systems, such as Windows, Linux, and macOS, implement paging as part of their memory management strategies.
