Windows Server Administration Fundamentals — Question 117

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?

Answer options

• A. Input/output (I/O) port addresses
• B. Direct memory access (DMA) channels
• C. Memory address ranges
• D. Interrupt request (IRQ) line numbers

Correct answer: B

Explanation

The correct answer is B, as Direct Memory Access (DMA) channels allow devices to communicate with memory without involving the CPU, enabling faster data transfer. In contrast, I/O port addresses, memory address ranges, and IRQ line numbers all require the CPU to manage and process their operations, thus involving the processor.
