Briefly outline four goals of input output system software?

1. Efficient data transfer: Input output system software aims to facilitate the efficient transfer of data between the computer's hardware devices and the operating system, ensuring that data is processed and transmitted quickly and accurately.

2. Device management: The input output system software is responsible for managing the various input and output devices connected to the computer, such as keyboards, mice, printers, and monitors. It ensures that these devices are properly recognized and configured to work with the operating system.

3. Error handling: Input output system software is designed to handle errors that may occur during data transfer or device communication. It includes error detection mechanisms and recovery procedures to ensure that data is not lost or corrupted in the event of a system failure.

4. Resource allocation: The input output system software allocates system resources, such as memory and processing power, to input and output operations in an efficient manner. It prioritizes tasks based on their importance and ensures that all devices have access to the resources they need to function properly.

1. Device management: Manage the allocation and deallocation of I/O devices, ensuring fair access and efficient utilization.
2. Error handling: Detect and recover from I/O errors to maintain data integrity and system stability.
3. Data buffering: Cache data between I/O devices and memory to improve performance and reduce latency.
4. User interface masking: Provide a simplified and abstract interface for user applications to interact with I/O devices, hiding the complexity of the underlying hardware.
