Detailed explanation-1: -The technique of data transfer between a microcomputer and an external device is called input/output (I/O). One communicates with a microcomputer via the I/O devices interfaced to it. The user can enter programs and data using the keyboard on a terminal and execute the programs to obtain results.
Detailed explanation-2: -A computer system can function without peripheral devices but it cannot function without core components. Examples of core components are CPU, motherboard, power supply, RAM, and ROM. Keyboard, mouse, monitor, printer, scanner, and USB drive are examples of peripheral devices.
Detailed explanation-3: -A DMA Controller takes over the buses to manage the transfer directly between the I/O device and memory. These two control signals in the CPU that facilitates the DMA transfer.
