2power 12 storage locations
fof n lines 2^n locations are available

The storage locations can be decide by using the following formula:

(2 power n) this gives the storage locations, where n is the number of address lines.
Here the no. of address lines are 12 i.e. n=12
Therefore (2^12) gives 4096.

(2)of power P= M

M= MO. OF MEMORIES LOCATIONS
P= NO . OF ADDRESS LINES
SO GIVEN DATA WAS " P "
GET "M"

The electronic devises deals with binary number(2).

So 12 address lines can have 2^12 memory locations.

Each line can be addressed either 0 or 1 so each address line can be addressed in two ways. There are total 12 address line
(2*2*2.......2) (12 times therefore 2^12 address line are required).

I agree with you @Vijay.

12 address lines can have 2^12 memory locations.
