Total questions: 10
Worksheet time: 10mins
How does the Hardware trigger an interrupt ?
Sending signals to CPU through system bus
Executing a special program called interrupt program
Executing a special program called system program
Which operation is performed by an interrupt handler ?
Once done handling, bringing back the system to the original state it was before the interrupt occurred
Saving the current state of the system
All of the above
The following is not a layer of IO management module
MCS (Management Control System)
FS (File System)
PIOCS (Physical Input Output Control System)
If one or more devices use a common set of wires to communicate with the computer system, the connection is called
CPU
Monitor
Bus
A ____ a set of wires and a rigidly defined protocol that specifies a set of messages that can be sent on the wires.
bus
node
port
The hardware mechanism that allows a device to notify the CPU is called
polling
interrupt
driver
The CPU hardware has a wire called __________ that the CPU senses after executing every instruction.
interrupt request line
interrupt bus
interrupt receive line
In general the two interrupt request lines are :
maskable & nonmaskable interrupts
blocked & nonmaskable interrupts
maskable & blocked interrupts
The ________ can be turned off by the CPU before the execution of critical instruction sequences that must not be interrupted.
nonmaskable interrupt
maskable interrupt
blocked interrupt
The interrupt vector contains :
the memory addresses of specialized interrupt handlers
the interrupts
the identifiers of interrupts
