Programmed vs Interrupt I/O Explained by Senthilkumar Krishnamoorthy is a document available to read on EtoBox.
i. Programmed I/O involves the CPU directly monitoring and controlling all data transfers between memory and I/O devices as part of a program. Interrupt-initiated I/O allows I/O devices to signal the CPU when a transfer is needed, freeing the CPU to work on other tasks in the meantime. ii. Direct memory access (DMA) bypasses the CPU altogether by allowing I/O devices to access memory directly via a DMA controller, improving transfer speeds for high-speed devices like disks. The DMA controller manages memo
