What are the four main resources a hardware component might use? Describe each.

What will be an ideal response?


The four main resources a hardware component might use are:
* Direct memory access (DMA) channels-A legacy method for allowing devices to communicate directly with system memory instead of passing data through the processor. Typically used for sound cards.
* Input/output (I/O) ranges-Addresses at which a device can be communicated with. A single device can have several addresses, with each address allowing access to a particular device feature or component.
* Interrupt request (IRQ) lines-A mechanism for devices to request time from the CPU.
* Memory address ranges-Address ranges in system memory that are dedicated to the device.
