Input/output connects computation with users, networks, sensors, storage, and actuators.

supported

The CPU can communicate through memory-mapped or port-mapped registers, while interrupts notify the OS of events and DMA transfers blocks without requiring the CPU to copy every byte.

supported

Device logs, interrupt counters, bus traces, throughput benchmarks, latency measurements, and driver behavior reveal the I/O pipeline.
