Textbook Problem

Use the Internet to search for information on real-time operating systems. Identify the key differences between real-time and non-real-time operating systems. Identify three situations in which real-time operating systems are needed.

Explanation of Solution

Real-time operating system:

  • It is a multiprogramming system that aims at executing real time applications.
  • This operating system immediately responds to the given input. The task in this system is completed within a specified period of time.
  • This OS is a time-sharing system which is based on clock interrupts.
  • This operating system execute the process by using priority.
    • Once a high priority process arrives into the system, low priority process preempted to support the high priority process.
  • There are two types in the real-time operating system:
    • Soft real-time operating system:
      • In this operating system, a process might not be performed in given limit. This type is able to cross the limit without damaging the given machine.
      • Example for this type is multimedia transmission and reception.
    • Hard real-time operating system:
      • In this operating system, a process should be executes in given limit...

Explanation of Solution

Difference between real-time and non-real-time operating system:

The difference between the real-time and non-real-time operating system is given below:

Real-time operating systemNon-real-time operating system
This operating system is deterministic.This operating system is not deterministic.
It is time sensitive.It is time insensitive.
It can’t use virtual memory.It can use concept of virtual memory.
It is mostly used in the embedded application.It is mostly used in the desktop and personal computer...

Explanation of Solution

Three situations are needed for real-time operating system:

The three situations in the real-time operating system are ATM machine, aircrafts and medical equipment’s.

  • Reasons for ATM machine using real-time operating system:
    • People can quickly access their account.
    • People can also withdrawal amount from the ATM machine at any time and within seconds.
  • Reasons for aircrafts using real-time operating system:
    • Aircrafts use real-time system for the passenger’s safety...
