Web7 feb. 2024 · A modem is a gadget that is used to transmit digital data through an Analog system. The term is determined from”modulator-demodulator”. Modems are sorted based on two criteria: The first is Data sent/unit time. And the second one is Change in the state of the signal/unit time. The first modem was used during the ’60s decade, to interface ... Web1 Answer. Sorted by: 4. First, "fastest" is an ambiguous term--it can refer to latency or throughput/bandwidth. Second, DMA is orthogonal to interrupts and polling. I.e., the completion of the DMA can trigger an interrupt or be determined by polling an I/O register (or the memory that is being written in some cases).
