a) For each approach to representing files below, show how to calculate the physical address from the logical address using the example logical address for a system with block size 512 by presenting the formula and explaining how to apply its results: (2 pts each) Every sblock of pointers is 512.

i) contiguous, LA=1028

ii) linked, LA=2039

iii) indexed, LA=5066

iv) file allocation table, LA=8049

v) double indirect, LA=236468

(b) For each method in (a) above give one positive and one negative characteristic.
