Description: Virtual memory segmentation is a memory management technique that divides virtual memory into segments based on the logical structure of a program. Unlike paging, which divides memory into fixed-size blocks, segmentation allows each segment to have a variable size, aligning more closely with the logical organization of data and functions within a program. Each segment can represent different types of data, such as code, static data, dynamic data, or stacks, facilitating memory management and access. This technique enables operating systems to manage memory more efficiently, as segments can be loaded and unloaded as needed, optimizing the use of physical memory. Additionally, segmentation provides a natural way to implement memory protection, as each segment can have its own access permissions, helping to prevent unintended access between processes. In summary, virtual memory segmentation is a fundamental technique in modern operating system memory management, enhancing efficiency and security in memory resource handling.
