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
