Answer:
ans is in exaplation
Step-by-step explanation:
The processor can usually address a memory space that is much larger than the memory space covered by an individual memory chip.
In order to splice a memory device into the address space of the processor, decoding is necessary.
For example, the 8088 issues 20-bit addresses for a total of 1MB of memory address space.
However, the BIOS on a 2716 EPROM has only 2KB of memory and 11 address pins.
A decoder can be used to decode the additional 9 address pins and allow the EPROM to be placed in any 2KB section of the 1MB address space
