Given the following Omega network, which allows 8 CPUs (P0 through P7) to access 8 memory modules (M0 through M7):

a) Show how the following connections through the network are achieved (explain how each switch must be set). Refer to the switches as 1A, 2B, etc.:
i) P0 M2
ii) P4 M4
iii) P6 M3
b) Can these connections occur simultaneously, or do they conflict Explain.
c) List a processor-to-memory access that conflicts (is blocked) by the access P0 M2 and is not listed in part (a).
d) List a processor-to-memory access that is not blocked by the access P0 M2 and is not listed in part (a).
