When this option is available, the I/O queue should be prioritised above the process execution queue. In what ways may this be beneficial? Who knows what will take place if there is a disruption in the I/O. It is unclear at this time if this will have an effect on the maximum burst rate of the CPU. I'm not really clear on the point you're trying to make here.

Fundamentals of memory

A collection of connected storage devices form the memory unit. It is a space to store data and instructions required for processing. Information is stored in a memory unit in the form of bits. There are two types of memory namely:
