Input/Output

A Computer handles several interrupt sources of which the following are relevant for this question: $$ * \,\,\,$$ Interrupt from $$CPU$$ temperature sensor (raises interrupt if $$CPU$$ temperature is too high) $$ * \,\,\...

A CPU generally handles an interrupt by executing an interrupt service routine

Normally user programs are prevented from handling $${\rm I}/O$$ directly by $${\rm I}/O$$ instructions in the for $$CPU$$ having explicit $${\rm I}/O$$ instructions, such $${\rm I}/O$$ protection is ensured by having th...

A processor needs software interrupt to

Consider a disk with following specifications: $$20$$ surface, $$1000$$ tracks/surface, $$16$$ sectors/track, data density $$1$$ $$KB/sector,$$ rotation speed $$3000$$ $$rpm.$$ The operating system initiates the transfer...

Which of the following requires a device driver?

Which of the following does not interrupt a running process?

System calls are usually invoked by using:

Which of the following is true?

Which of the following is an example of spooled device?

Which of the following devices should get higher priority in assigning interrupts?

Which of the following is an example of spooled device?

Which of the following is an example of a spooled device?

State whether the following statement are TRUE or FALSE with reason. The data transfer between memory and $${\rm I}/O$$ devices using programmed $${\rm I}/O$$ is fasterthan interrrupt-driven $${\rm I}/O$$.

On receiving an interrupt from an $${\rm I}/O$$ device the $$CPU$$:
