Operating System is like the heart of a computer. It is a system software responsible for controlling other software and different hardware. It is the bridge that gap between software and hardware. 

Different types of Operating System:

  • Batch Operating System
    The second generation of computers used Batch Operating System as the first operating system. The batch Operating system does not interact with the computers directly but instead took the input in a punch card. Each of these punch cards has a different form of data that was executed by the operating system in different batches, for example- payroll systems.

                 Advantages:    

  • Data in the same batch is executed faster
  • A single batch can be shared amongst multiple users.

  • Lesser idle time

  • Better CPU utilization.


    Disadvantages:

  • Difficulty in debugging

  • Costly

  • Falls into an infinite loop in case a job fails.


  • Distributed Operating System
    One of the latest advancements in the cyber world, using this OS various autonomous computers can communicate with each other. It is a collection of independent, interconnected, networked, separate computational nodes (separated at the physical level) for example- Locus.

                Advantages:

  • Being independent, failure in one system will not affect the functioning of the other systems.

  • Reduced delay in the data processing.

  • Highly scalable.

    Disadvantages:

  • If the main network fails, then the OS becomes useless.

  • Very expensive.

  • Real-Time Operating System

These types of OS are designed to serve those applications which carry out their task in real-time, without any potential buffer delays. It is further classified into two types- Hard Real-Time Systems and Soft Real-Time System. Examples- Medical Imaging Systems, Weapons and robotics systems, etc.

              Advantages:

  • Maximum consumption of the system and connected devices, hence greater output.

  • Typically error-free.

  • Most efficient memory allocation.

    Disadvantages:

  • Many complex algorithms involved.

  • Expensive.

  • Less efficient when it comes to task switching.
