This set of MCQs helps students to learn about interrupts and exceptions which are unexpected events which will disrupt the normal flow of execution of instruction(that is currently executing by processor). An exception is an unexpected event from within the processor. Interrupt is an unexpected event from outside the process.
Into how many parts does the interrupt can split the software?
Which of the following allows the splitting of the software?
Wait statement
Ready
Interrupt
Acknowledgement
Which part of the software is transparent to the interrupt mechanism?
Background
Foreground
Both background and foreground
Lateral ground
Which part of the software performs tasks in response to the interrupts?
Background
Foreground
Lateral ground
Both foreground and background
Which code is written as part of the ISR?
Data receive code
Sequential code
Data transfer code
Concurrent code
Which factor depends on the number of times of polling the port while executing the task?
Data
Data transfer rate
Data size
Number of bits
Which of the following can improve the quality and the structure of a code?
Polling
Subroutine
Sequential code
Concurrent code
Which of the following are asynchronous to the operation?
