A thread will immediately acquire a dispatcher lock that is the signaled state. Exception is a very general thing. Interrupts may be triggered by either hardware of software.

The CPU hardware has a wire called _____ that the CPU senses after executing every instruction. A system call is a programmatic way in which a computer program requests a service from the kernel of the operating system it is executing on while an interrupt is an event that is triggered by external components that alert the CPU to perform a certain action. INT 0x80h is an old way to call kernel services system functions.

F 26 Processors for most mobile devices run at a slower speed than a processor in a desktop PC. System calls provide programs running on the computer an interface to talk with the operating system. C TF A system call is triggered by hardware.
