Answer / prasanna hugar

1) 12 address is ma12 address is mapped to 2^12 = 4096 bits
2) 4096/8 = 512bytes( dividing by 8 because converting bits
to bytes 8 bits = 1 bytes)
3) 512/1024 = 0.5 K bytes

I think my answer is cleared your problem

Answer / ahmed eldesokey

12 address is mapped to 2^12 = 4096 byte
so
4096 byte / 1024 = 4 Kbyte

then the answer is [ d ] none it is mapped on 4 KB

Answer / saki

2^n bits n is no of address lines so 2^12=4096 bits
4096/8= 512 bits which is 0.5 k byte

Answer / divya

Here 2^12=4096 but it is in bit so need to convert it into byte so we do 4096/8=512=0.5k byte. so the answer is b)
