WebInput and output devices are used to enter data as well as to take out data from microprocessor to peripheral. This interfacing is referred to as the mapping of I/O either by using peripheral devices, i.e. I/O or by memory. When the processor, main memory and I/O share a common bus, two modes of addressing are possible: I/O mapped I/O

WebPIO stands for Programmed Input/Output, which is a protocol for data transfer. Since it involves the CPU, the use of PIO mode for data transfer can slow a computer down considerably. On the contrary, DMA (Direct Memory Access) does not involve the CPU. Rather, the involved components move data directly to and from RAM, bypassing the … Web19 jan. 2024 · Simplex is the data transmission mode in which the data can flow only in one direction, i.e., the communication is unidirectional. In this mode, a sender can only send data but can not receive it. Similarly, a receiver can only receive data but can not send it.
