Explanation / Answer

1) READ ONLY MEMORY

2) IF YOUR PROCESSOR IS OF 8 bit THEN ITS WORD SIZE IS 8 bit.

3) RANDOM ACCESS MEMORY

4) FALSE

5) 2

6) 1024

7)It depends on processor. For 8 bit processor 1byte = word,for 16 bit 2 byte=word

8)4

9)2power(20)

10)It depends on processor. For 8 bit processor word=2 nibble ,for 16 bit word= 4 nibble

11) a 1048576
