Consider a 20gb disk that has 20 surfaces over 10 platters. each platter has 256 tracks and the block size for the disk is 16kb. assume that the size of each track is the same. compute the size of each cylinder on the disk both in terms of the number of bytes and the number of blocks. also, compute the size of each track. identify the true statement below with respect to these computations.
a. each track has 4mbb. each track has 512 blocksc. each track has 128 blocksd. each track has 2mb
