Long description

The image consists of three parts. Part (a): There are 16 C P U placed in the form of squares in four rows and four columns and labeled 0 to 15. There is a vertical Priority block with eight partitions starting from the bottom to the top from 0 to 7. The 0 and the last partition have three threads in the form of circles connected via straight lines and labeled L, M, and N. The first partition is empty. The second partition has two threads J and K. The third partition has three threads G, H, and I. The fourth partition is empty. The fifth partition has a single thread F. The sixth partition has two threads D and E. The seventh partition has three threads A, B, and C. Part (b): There are 16 C P U placed in the form of squares in four rows and four columns that start from 0 to 15. In row 2, column 1, instead of number 4 C P U, A is marked and labeled C P U 4 is idle. There is a vertical Priority block with eight partitions starting from the bottom to the top from 0 to 7. The 0 and the last partition have three threads in the form of circles connected via straight lines and labeled L, M, and IN. The first partition is empty. The second partition has two threads J and K. The third partition has three threads G, H, and I. The fourth partition is empty. The fifth partition has a single thread F. The sixth partition has two threads D and E. The seventh partition has two threads B, and C. Part (c): There are 16 C P U placed in the form of squares in four rows and four columns that start from 0 to 15. In row 4, column 1, instead of number 12 C P U, B is marked and labeled C P U 12 is idle. There is a vertical Priority block with eight partitions starting from the bottom to the top from 0 to 7. The 0 and the last partition have three threads in the form of circles connected via straight lines and labeled L, M, and IN. The first partition is empty. The second partition has two threads J and K. The third partition has three threads G, H, and I. The fourth partition is empty. The fifth partition has a single thread F. The sixth partition has two threads D and E. The seventh partition has one thread C.
