Computers connected in distributed systems need to keep on for all time. These computers are either processing information of distributed application or running any service(s) to be provided in distributed system. But at all time all computers are not doing computations or remain idle. Similarly, service(s) providing by computers may not be accessing by any other computer(s) for certain period. So, it is not necessary to keep computers on during their idle period or period in which their service(s) is/are not being accessed. It can save tremendous amount of power.
