Final answer:
Device independent I/O software allows users to perform input/output operations without worrying about specific hardware. Examples include USB and PCL.
Step-by-step explanation:
Device independent I/O software is designed to allow users to perform input/output operations without having to worry about the specific hardware or device being used. It provides a consistent interface across different devices and operating systems. Some examples of device independent I/O software include Universal Serial Bus (USB), which allows for plug-and-play connectivity of devices to computers, and Printer Control Language (PCL), which enables printing on different printer models and brands.
