Long description

Part (a): There is a squared block labeled Single Processor and two circles labeled A and B from top to bottom. There is a horizontal block labeled the original file with two partitions labeled a and b. There is a horizontal block with three partitions labeled a, b, and c. From circle A, there is a downward arrow labeled 1. Write "c" points to a horizontal block with three partitions. From three partitions, there is a downward arrow is labeled 2. Read gets "abc". Part (b): There is a squared block labeled Client 1 and a circle labeled A. There is a horizontal block labeled the original file with two partitions labeled a and b. There is a horizontal block with three partitions labeled a, b, and c. From circle A, there is a downward arrow labeled 1. Write "c" points to a horizontal block with three partitions. There is a second squared block labeled File server and there is a horizontal block labeled the original file with two partitions labeled a and b. There is an upward arrow labeled 1. Read "ab" points to the first partition a and b of Client 1. There is a third squared block labeled Client 2 and there is a horizontal block labeled the original file with two partitions labeled a and b and a circle labeled B. From the partition of the second block File server, a downward arrow labeled 3. Read gets "ab" points to the partition of third block Client 2.
