👉 Computing pages, often referred to as computing pages or virtual memory pages, are fundamental components of modern computer systems that manage the allocation and organization of memory. When a program runs, it uses virtual memory to map its logical address space to physical memory or disk space. Each process is assigned a set of virtual addresses, and the operating system uses these to manage memory by dividing them into fixed-size blocks called pages. When a program accesses data that isn't currently in physical memory, the operating system uses a technique called paging to either swap out less frequently used pages to disk (a process known as page replacement) or load them into physical memory. This allows for efficient use of limited physical memory and enables multitasking by providing each process with its own isolated address space. The size of these pages is typically chosen to balance efficiency and overhead, with common sizes ranging from 4KB to 64KB, depending on the system architecture.
