Description: The ‘Page Out’ refers to the process by which an operating system writes a memory page from the computer’s RAM back to the hard disk or another storage medium. This process is fundamental in memory management, especially in systems that use paging, where memory is divided into fixed-size blocks called pages. When physical memory fills up and space for new pages is needed, the operating system selects a page that is not actively being used and writes it to disk, thus freeing up space in RAM. This process not only allows the operating system to manage available memory efficiently but also helps maintain system performance by preventing physical memory overload. ‘Page Out’ is essential for implementing virtual memory, which allows systems to operate with more memory than they physically have available. Through this mechanism, systems can run larger applications and multiple tasks simultaneously, enhancing user experience and overall system efficiency.
