Types of Operating System

If you want to call yourself a technical person, then at least you should know about the operating systems and their types. In this article, you will get a clear idea about Operating Systems and their types. Here are the contents discussed in this article.

 What is an Operating system?

An operating system is computer software that acts as an interface between both hardware and software that are running in the computer. It is the prime software or core software that runs the other software in the system.  

For example, Personal Computer OS like Windows, Mac, and mobile OS like Android are mostly used by people. It is the first software that will be installed when you purchase a computer. 


Features of Operating Systems

  • Security Management – It provides three levels of securities to the user end. They are – File access level, system level, Network level. 
  • The main feature of the Operating system is the user interface. It gives user-friendly functions to the users. Each Operating system has its operating system. 
  • Next is process management. The OS is the software that runs all the programs and allocates the resources like RAM, CPU core, etc… To the respected functions. 
  • The next important feature is memory management. It controls the hardware assign memory space to respected functions
  •  Scheduling – It manages the regular update and other schedules the task based on the importance of them.

Types of Operating Systems:

One of the common mistakes people make while discussing the types of Operating systems is they will confuse the type with brands or products. For example, Windows OS, macOS, Linux are different products of Desktop or Computer OS. 

Whereas Android and Windows are different, the former is Mobile OS and the latter is a Computer OS. There are different types of operating systems and they can be classified under different categories like User-friendliness, device, use, and cost. 

Here are the most popular types of Operating System in use –

1.Batch Operating system

This and the operating system do not communicate with the operator directly. The operator will collect the similar jobs requiring the same response and group them as a batch. Multiple users can easily use the batch-based operating system. You can easily manage large work repeatedly as the idle time of the batch system is very low. 

At the same time there are some disadvantages with the batch system. Importantly, operators should have enough knowledge to operate the batch Operating system. It is costly and hard to debug. The best examples of Batch Operating Systems are – Payroll Systems, Bank Statements, etc…

2.Distributed Operating System

 It is the widely used type of operating system in the world; here multiple computers are connected in a single shared communication network. Each computer will have its own memory space and CPU. It is also known as loosely coupled systems. 

The major advantage of using these types of operating systems is that one user can access the files of another user that is not stored in his system. But at the same time, the failure of the main network will collapse the whole network or system. Examples of distributed Operating Systems are – Locus, etc…

3.Time-sharing Operating Systems

Here each task is given a certain time to execute so the system can work smoothly. They are also known as multi-tasking systems. The task can be given from single or multiple users and each user will get the time of CPU as they use a single system. 

There is a reliability problem and data communication problem. However, the idle time of the CPU is reduced. Examples of the time-sharing operating system – Multics, UNIX, etc…

4.Real-Time Operating System

This type of operating system gives the real-time response, that is the time interval between each response will be very small. Real systems are used where the time is very strict like missile systems, air traffic systems, etc…  

They further classified two types – 

  • Hard Real-Time systems and
  • Soft Real-Time Systems.

 You can find examples for the real-time operating systems in scientific experiments, medical imaging systems, etc…
