In a time-sharing system we have 4 jobs A,B,C,D. Each job has 1s CPU only. Context switch time is 0.125s (it includes all necessary I/O activity). Only one job can be in MM (Main Memory) at any one time. CPU utilization means fraction of time CPU is executing code of A, B, C, or D. Originally all jobs in SM (Secondary Memory i.e. Disk) and no job in MM. At conclusion, all jobs in SM and no job in MM as well. Case 1: [ts=1s; ts is time-slice] (1a) What is the CPU utilization ? (1b) What is the minimum response time? (1c) What is the maximum response time ? Case 2: [ts=0.5s] (2a) same as (1a) (2b) same as (15) (2c) same as
