How much space will be required to store the bitmap of a 1.3 GB disk with 512 bytes block size ?
Correct Answer: A
Question 645 Explanation:
Given data,
— bitmap=1.3 GB
— Block size=512 bytes
— How much space will be require to store the bitmap=?
Step-1: First we have to find total number of blocks
Number of blocks = disk size/ block size
= 1.3 GB(1.3*230 GB) / 512 Bytes(29 bytes)
= 1.3*221 bits
= 1.3*2MB
= 2.6 MB
= (2.6*1024) / 8KB
= 332.8 KB
— bitmap=1.3 GB
