MCQ IN COMPUTER SCIENCE & ENGINEERING

Detailed explanation-1: -Answers. Explanation: This forms an imporatant part of the Real time system since if a process arrives with greater priority then it raises an interrupt and the other process is stopped and the interrupt will be serviced.

Detailed explanation-2: -What is an interrupt? An interrupt is a signal emitted by a device attached to a computer or from a program within the computer. It requires the operating system (OS) to stop and figure out what to do next. An interrupt temporarily stops or terminates a service or a current process.

Detailed explanation-3: -Interrupts are important because they give the user better control over the computer. Without interrupts, a user may have to wait for a given application to have a higher priority over the CPU to be ran. This ensures that the CPU will deal with the process immediately.

Detailed explanation-4: -An interrupt is an event that alters the sequence in which the processor executes instructions. An interrupt might be planned (specifically requested by the currently running program) or unplanned (caused by an event that might or might not be related to the currently running program).

Detailed explanation-5: -Interrupts are an event that causes a program to stop and start executing another program. Interrupts are like a phone call from some device telling the program to stop executing and execute some other code instead.
