[8 marks totall 10 identical processes are running on a computer system and the CPU utilization is 60%. 10 GB of main memory is used to hold all 10 running processes. The system is required to run an additional 5 processes. Assume that all processes are the same. The formula for CPU utilization is CPUuil 1-p 1. 12 marks] What does the computer system require if all 15 processes are to run in main memory without using disk swapping? a) b) [4 marks] If 15 processes can run in main memory, calculate the CPU utilization and explain your result. [2 marks] If the processing speed of the CPU is increased, will CPU utilization improve? (explain) c)
