Define dynamic linking.
Dynamic linking is same to dynamic loading, rather that loading being postponed unless execution time, linking is postponed. This feature is usually used with system libraries, like language subroutine libraries. A stub is contained in the image for each library-routine reference. The stub is a small piece of code that shows how to locate the appropriate memory-resident library routine, or how to load the library if the routine is not already present.

Virtual addresses are made up of two parts: the ?rst part is the page number, and the second part is an offset inside that page. Suppose our pages are 4kb (4096 = 212 bytes) long,
The optimal replacement policy, called OPT, is to evict the page which will be accessed farthest into the future. Since we can't predict the future precisely, we can't implement OP
