As part of the configuration process, Windows assigns a number of system resources to the device
being installed to ensure that the device operates simultaneously with the other expansion cards.
Which of these system resources do not involve the processor?

A.
Input/output (I/O) port addresses

B.
Direct memory access (DMA) channels

C.
Memory address ranges

D.
Interrupt request (IRQ) line numbers

Explanation:
As part of the configuration process, Windows assigns the following system resources to the device
being installed to ensure that the device operates simultaneously with the other expansion cards:
Interrupt request (IRQ) line numbers: It is a signal sent by a device for obtaining the attention of the
processor when the device is ready to receive or send information. A unique IRQ number must be
assigned to each device.
Direct memory access (DMA) channels: These are the memory access channels that do not involve
the processor.
Input/output (I/O) port addresses: It is a channel through which transfer of data takes place between
a device and the processor.
Memory address ranges: These are portions of computer memory that are allocated to a device and
can be used by a program or the operating system. All devices are generally allocated a range of
memory addresses.
