Any operating system that allows for "paging" or "swapping" is capable of this.
Paging has many advantages. First of all, paging allows you to relocate memory areas to other places where they are more useful. For example, any operating system must divide memory in two areas, one for the operating system itself (OS, data, management tables, ...) and one for the user programs. The area for the OS must be subdivided into areas to store each driver and its data. The area for the user must be subdivided to store each program and its data.
Some Operating Systems periodically look for pages that have not been recently referenced and add them to the Free page queue, after paging them out if they have been modified.

The question is not very clear - in general the implementation of paging is too complex to answer in a Wiki answer entry; I suggest you take a look at any Operating System theory book.

"Paging" is when the operating system writes contents of RAM memory to disk, to free space for other uses.A paging algorithm specifies which RAM content to page (write to disk) when it needs more space.See related link.

Demand paging is a process which involves the copying and relocation of data from a secondary storage system to random access memory (RAM), a main memory storage system. Demand paging copies and relocates data to facilitate the fastest access to that data. Once the data is relocated, demand paging sends a command to the operating system to inform it that the data file or files are now ready to be loaded. Demand paging is performed on demand, or after a command has been sent to retrieve specific data.
Multi-level paging in operating systems can improve system performance by reducing the time needed to access memory. It does this by breaking down the page table into smaller, more manageable parts, which allows for faster lookups. Additionally, multi-level paging can help with memory management by efficiently organizing and managing memory resources, leading to better utilization of available memory.
Operating System
Paging is a way for the operating system to load data from a storage device onto RAM. When there is insufficient amount of space in RAM and if a page file is enabled, it will swap data between RAM and the swap file (typically on a storage device).
Paging refers to the division of address spaces into fixed size units and the logical addresses are in the form of tuples. On the other hand, segmentation is the dividing of address spaces into a defined number of segments.
