Which bus signal line allows a device to request the processor immediate attention?
Interrupt
What is a communications line between a device and the processor?
I believe it is interrupt request line.
When a computer device is in need of immediate attention it sends the OS?
An interrupt request, or IRQ
What is interrupt vector?
When a processor is interrupted to do a particular task,Program counter should be loaded with the the address of subroutine(task).If the processor automatically generates the address then it is known as vectored interrupt.for example if 8085 microprocessor is interrupted through RST 5.5 pin,then processor multiplies 5.5 by 8 and converts it to Hex address.If user has to provide address of subroutine using CALL instruction then it is known as non vectored interrupt
If a processor requests something from a device and the device is not ready what does the device do?
To sum this up there are 3 basic components to this equation, Operating system/Drivers/Hardware. The operating system would request a certain action to be carried out to the device using the processor as a means of processing the information being sent this would then communicate with the device driver which allows the operating system and hardware to run with each other, however if the device is not ready and there is an incoming process the device will simply not be able to pursue this action and nothing will happen. EDIT: Cyris69 The Device issues a "Wait State" http://en.wikipedia.org/wiki/Wait_state
When a device needs the CPU to perform a task what does it need to do?
The device needs to signal the CPU to get its attention. It typically does this through an interrupt request line (IRQ).
Why you need interrupt?
An interrupt is a signal from a device attached to a computer or from a program within the computer that causes the CPU to stop executing the current program and figure out what to do next. It enable input/output device communicate or get the attention of the processor, and execute a program that need more attention.
A is a clip-on device that mounts on top of the processor fingers or fins at its base pull the heat away from the processor?

If the processor requests something from a device and the device is not ready the device issues a?
wait state!! :)
What are the examples of of processing device?
Processor is a big example of process device
What is a device that is externally connected to and under the control of the central processing unit?
No, the printer has a internal processor that manages its functions, but yes, it is a device that connects to the system unit. the computer's processor HELPS managing it, but the printer's processor do the hard stuff
What does the microprocessor in PDA do?
It's the brain of the device. It is the processor.
