I/O Controllers
I/O (input/output) controllers are electronic components that act as a bridge between the processor and external devices such as peripherals, storage devices, and networking devices. They are responsible for sending and receiving data between the processor and these external devices.I/O controllers typically have multiple input and output ports, allowing them to handle a wide variety of devices. They also have built-in functionality for converting data between different formats, such as parallel to serial, to ensure efficient communication between devices.In addition, I/O controllers have advanced features such as interrupt handling, DMA (direct memory access) control, and error correction, which helps to offload some of the processing tasks from the CPU and improve the overall performance of the system.Overall, I/O controllers play a crucial role in facilitating communication and data transfer between the processor and external devices, making them an essential component in modern electronic systems. They also help to simplify the design of complex systems, making them more user-friendly and efficient.
