What is segment map table?

A segment map table is a data structure used in computer systems, particularly in memory management, to keep track of the segments of memory allocated to various processes. It maps logical addresses to physical addresses, allowing the operating system to efficiently manage memory allocation and deallocation. Each entry in the table typically contains information about the segment's base address, limit, and access permissions, facilitating effective memory protection and organization. This structure is crucial for implementing segmentation, which divides a program's memory into logical segments for better modularity and protection.
