Description: The logical address space is the range of addresses that a program can use, which is independent of the physical memory layout. This concept is fundamental in memory management of computer systems, as it allows programs to access an amount of memory that can be larger than the physical memory available in the system. Each process in a modern operating environment has its own logical address space, meaning that each program can operate as if it has exclusive access to all memory, without interfering with other processes. This is achieved through techniques such as paging and segmentation, which translate logical addresses to physical addresses. The separation between logical address space and physical memory not only enhances system security and stability but also facilitates multitasking, allowing multiple processes to run simultaneously without conflicts. Additionally, the use of logical address spaces enables the implementation of advanced features like virtual memory, where the operating system uses storage devices as an extension of RAM, thus increasing the capacity of programs to handle large volumes of data. In summary, the logical address space is an essential component in the architecture of modern computer systems, providing a controlled and efficient environment for application execution.
