Memory management techniques in Operating Systems include:
1. Memory Partitioning: Dividing the memory into equal-sized segments for different processes to use. This can be fixed partitioning (each process gets a fixed amount of memory) or dynamic partitioning (memory is allocated dynamically as needed).
2. Paging: Breaking up a program's memory into small, fixed-sized pages and storing them on disk when not in use. When a page is needed, it is loaded into physical memory.
3. Segmentation: Dividing a program's memory into logical segments based on its requirements (e.g., code segment, data segment). Each segment can be of any size and is managed separately by the operating system.
