Page replacement algorithms are crucial for managing the contents of memory in a virtual memory system, determining which pages to swap in and out of physical memory to optimize performance. These algorithms strive to minimize page faults and improve system efficiency by predicting which pages are least likely to be needed soon.

Physical memory, often referred to as RAM, is the hardware component in a computer that stores data temporarily for quick access by the CPU, enabling efficient processing of tasks. It differs from storage memory in that it is volatile, meaning it loses its contents when the power is turned off, allowing for faster read and write speeds compared to non-volatile storage like hard drives or SSDs.

System efficiency refers to the ability of a system to achieve its objectives with minimal waste of resources, such as time, energy, and materials. It is often measured by the ratio of useful output to total input, and improving efficiency is crucial for optimizing performance and sustainability.
