Description: A logical page is a fixed-size block of logical memory that is mapped to a physical page in memory. This concept is fundamental in the memory management of modern operating systems, as it enables the implementation of virtual memory. Logical memory refers to the memory address that a program uses, while physical memory is the actual address in RAM. Logical pages allow operating systems to divide memory into manageable segments, facilitating the efficient loading and storage of data. Each logical page typically has a standard size, commonly 4 KB, although it can vary depending on the system architecture. This fixed size simplifies memory management, as the operating system can perform memory allocation and deallocation operations uniformly. Additionally, logical pages enable the implementation of techniques such as paging, which helps optimize memory usage and prevent issues like fragmentation. In summary, logical pages are an essential component in the architecture of operating systems, as they allow for efficient and flexible memory management, improving the overall performance of the system.
