Describe the difference between a time-sharing system and a real-time system.
What will be an ideal response?
A time-sharing system is a central computer system that is used by multiple users and applications simultaneously. Most of the time-sharing system's work is done in batches, using batch processing. A real-time system is an operating system that receives and processes inputs and produces the required outputs in a specifies amount of time. A real-time computer program immediately performs calculations and returns the answer using sequential processing instead of batch processing.
