Overlay (overlay) is the ability to place modules in memory in such a way that
one of them (the root one) was constantly there, and the rest - n-variably loaded during execution of the program in the same area, replacing and overlapping each other

one of them (the root one) was constantly there, and the rest - n-variably loaded after the execution of the program in the same area, replacing and overlapping each other
one of them (the root one) was constantly there, and the rest - n-variably loaded before the program was executed in the same area, changing and overlapping each other
all the modules were alternately loaded during the execution of the program in the same area, changing and overlapping each other
