How do different operating systems manage memory?

Different operating systems use various memory management techniques, such as paging, segmentation, and virtual memory.

Can you explain what paging is?

Paging is a memory management scheme that eliminates the need for contiguous allocation of physical memory, allowing for more efficient use.

What about segmentation? How is it different from paging?

Segmentation divides memory into variable-sized segments based on logical divisions, while paging divides it into fixed-size blocks.

Which OS uses these techniques effectively?

Operating systems like Windows, Linux, and macOS implement both paging and segmentation to optimize memory usage.
