I am interested in one detail in the global page replacement strategy:
During the work of process A, there was a need to replace the page. The page replacement algorithm has selected as a “victim” the frame currently belonging to the virtual page k of process B.
When process B continues its work, its virtual page k will point to the frame containing the data of process A.
How do operating systems handle this situation?

What changes occur to address space, pages and segments of a process when we allocate memory at runtime using malloc()/calloc()/realloc() system calls, on Linux and Windows? What happens to address space, pages and segments when we free() those allocated memory.

can this algorithm have same number[i] values or t[i] value even after having while(choosing[j]) condition below if yes then what is use of this condition when i researched i found that it can theoretically have same values but not practically can anyone explain why choosing=true/false is done here then?
