Overlay 0 will implement first. After the implementation of 0, it will call another overlay to implement. A few overlay systems were highly complex, permitting multiple overlays in memory at once. The idea of overlay is to remain in memory only those instructions are needed at any given time.
Consider a computer system with a 32-bit logical address and 4KB page size. The system supports up to 512MB of physical memory. How many entries are there in a conventional single-
