3 votes 3 votes Answer is : (c) 64 Explanation: We need 256 Kbytes, i.e., 256 x 1024 x 8 bits. We have RAM chips of capacity 32 Kbits = 32 x 1024 bits. (256 * 1024 * 8)/(32 * 1024) = 64 chips learner_geek answered Jan 5, 2018 learner_geek comment Share Follow See 1 comment See all 1 1 comment reply Vijay Kusumakar commented Dec 17, 2019 reply Follow Share How can we know that RAM capacity is given in bits or bytes.
