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.

The joy of being a computer engineer lies in the amazing ability of complexity synthesis that lies at my disposal. The inexplicable sense of magic‚ which I felt when my first "hello world " got displayed on screen‚ is something I have never experienced in any other phase of my academic pursuit “Hello‚ World”; the first and perhaps the simplest of the programs any novice programmer executes.
