Final answer:
Attention in I/O systems of operating systems must be maintained by ensuring responsiveness and efficient data handling. I/O system design focuses on interactive tasks with immediate feedback to hold user engagement. System support for attention is achieved by developing intuitive user interfaces and applications that manage resources effectively and minimize distractions.
Step-by-step explanation:
Design Issues for I/O in Operating Systems
Designing Input/Output (I/O) systems in operating systems (OSs) is a critical task that involves addressing several issues for efficiency and user satisfaction. One of the central design issues is how to maintain attention to real-time I/O tasks efficiently. Systems must be designed to hold the user's attention by being responsive and avoiding unnecessary delays.
Another aspect of I/O design relates to how different tasks maintain attention. Tasks that are interactive and give immediate feedback are likely to keep the user's engagement. Consequently, OS designers must create I/O systems that support this through quick feedback loops and efficient data handling.
Lastly, designing systems to support attention implies the development of user interfaces that are intuitive and applications that minimize distractions. This involves prioritizing tasks, managing resources cleverly, and maintaining an appealing visual design that does not overwhelm the user. With these factors in mind, the OS provides a seamless experience that satisfies the performance and usability needs.
