WebMar 4, 2024 · The direct memory access (DMA) I/O technique provides direct access to the memory while the microprocessor is temporarily disabled. A DMA controller temporarily borrows the address bus, data bus, and control bus from the microprocessor and transfers the data bytes directly between an I/O port and a series of memory locations. WebThe data bus is used to carry data signals only. A data bus is defined broadly in general. It carries the data; the internal buses carry or transfer information or data within the processor, whereas external buses transfer data among processor and memory. For the read and write operations, the same data bus is used.
