What is the primary function of Direct Memory Access (DMA) in computer systems?
What is the primary function of Direct Memory Access (DMA) in computer systems?
- Improve the speed of the central processing unit (CPU)
- Increase the involvement of the CPU in data transfers
- Reduce the workload on the CPU during data transfer operations (correct)
- Eliminate the need for peripherals in data transfers
How does DMA differ from traditional I/O operations involving the CPU?
How does DMA differ from traditional I/O operations involving the CPU?
- Traditional I/O involves more memory allocation
- DMA limits the types of peripherals that can be used
- Traditional I/O requires constant CPU supervision
- DMA uses a separate controller for data transfers (correct)
