What are the different memory management techniques in operating systems?

There are several memory management techniques, including paging, segmentation, and heap management. Would you like a detailed comparison?

Yes, please explain paging and segmentation.

Paging divides memory into fixed-size blocks, while segmentation divides it into variable-sized segments based on logical divisions. Paging can lead to internal fragmentation, whereas segmentation can lead to external fragmentation.

Which technique is more efficient?

It depends on the use case. Paging is generally more efficient for processes with fixed-size data, while segmentation is better for variable-sized data.

Can you give examples of when to use each technique?

Sure! Use paging for applications like databases that require quick access to fixed-size records, and use segmentation for applications like text editors that handle variable-length documents.
