[Marks=10] Resources: Printer (R1), Hard Disk (R2), CPU (R3) and RAM (R4) Processes: MS Excel (P1), MS Word (P2), Media Player (P3) and Calculator (P4) Resources: Printer = 1, Hard Disks = 2, CPU = 1, RAM = 1 MS Excel Holds Printer and wait for CPU and RAM. MS Word holds Hard Disk and RAM and waits for Printer and CPU. Media Player waits for Hard Disk. Calculator holds CPU. Write cycles in RAG if any
