Explanation / Answer

If you post more than 1 question, as per chegg guidelines I have to answer only the first one.

1.

n address lines can address = 2 ^ n memory              ........   ( 1 )

Now 1K = 1024                        ........   ( 2 )

Also,

2 MB = 2 * 1024 K

2 MB = 2048 K

From ( 2 ),

2 MB = 2048 K

= 2048 * 1024

= ( 2 ^ 11 ) * ( 2 ^ 10 )

2MB = 2 ^ 21

Hence, from ( 1 ) we can say that

No of address lines required = 21 address lines
