WebIn the case of timer interrupt, the kernel scheduler code may suspend the process that was running and allow another process to run. It is the presence of the scheduler code which enables multitasking. Software interrupts are processed much like hardware interrupts. However, they can only be generated by processes which are currently running. http://www.sci.brooklyn.cuny.edu/~jniu/teaching/csc33200/files/0910-ComputerSystemOverview02.pdf
