1.5 Modern OS are interrupt driven. Events are almost signaled by the occurrence of an interrupt or a trap‚ which caused either by an error or by a specific request from a user program that an OS service be performed .Dual-mode Operation allows OS to protect itself and other system components whereas Multimode Operation increasingly CPUs support multi-mode operations. System call provides the means for a user program to ask OS to perform OS tasks on the user program’s behalf. When a system callis

Proposed operating Philosophy of the Generator control system Project : Rooty Hill RSL Club Introduction The site is currently with mains power supplied through three transformers each of 1000KVA. Each transformer is connected to a dedicated switchboard with a fault level of 43KA at 1 second. All switchboards are not normally interconnected though they are connected to each other with a 1600A bus coupler which are locked by Integral Energy. Each switchboard is also served by a diesel
