Block I/O Controller

A Block I/O Controller manages the flow of data between a computer's processor and storage devices like hard drives or SSDs. It organizes data into fixed-sized blocks, coordinating read and write operations to ensure efficient, accurate, and timely data transfer. By handling multiple requests simultaneously and prioritizing tasks, it helps maintain system performance and reliability. Essentially, it acts as the traffic manager that directs data to and from storage units, enabling smooth communication between the computer's central processor and its storage media.
