What are the Different Types of Operating Systems?

What is Operating System:- This is software component of a computer system that is responsible for the management of all resources of computer system. The operating system (OS) acts as a host for the application program that runs on the machine. As a host, one purpose of the operating system is to handle the operating details of the computer’s hardware.

operating systemThis makes the application relieves applications and makes applications easier to write by managing these details. Almost all types of computers, including hand-held computers, desktop computers, supercomputers, and even modern video game consoles, use any type of operating system

Functions Are:

  • User Interface
  • Job Management
  • Task Management
  • Data Management
  • Device Management
  • Memory Management
  • Disk And File System
  • Networking
  • Graphical User Interfaces
  • Security

Uses of Operating System

The main use of an operating system is to ensure that the computer can be used and the user can do the exact same way that the command given by the user needs to be understood by the operating system that is in the computer or the device accordingly Can work. The ability of a single operating system makes everything much easier because the technique does not need to do many different processes that are told.

Other Uses Are:-

The operating system is essential for the operation of any computer. Even in a single-OS that appears, a computer performs many functions at once:

–  Display an image
–  Run the software
–  Polling for various signals

This is true for everything from NES, ATARI, DOS or Windows PC etc (I did not get into multi-threading)

A (single core) CPU can process a single instruction stream only once (thread). As such, it is to do all those things to jump between these different tasks. It gives the illusion of multitasking.

At a very basic level, an operating system is just a scheduler. In this, there is a list of processes requiring CPU time and provides access to each process one by one, or on the basis of the load.

Without it, you will get stuck arithmetic and 100% CPU time will be required for the output.

Operating Systems Used in Banks

  •   UNIX
  •  LINUX

Operating Systems Used in Mobile

  • Symbian OS
  • Windows Mobile
  • Palm OS
  • IOS

How Many Types of Operating System

Here below list of different types of operating systems , and describe each

1. Simple Batch System:

In the Batch processing operating system, all jobs (tasks) are executed in series nature on the computer system without any hindrance. In this system all processing performs automatically, and no need the insert manually input.

2. Multiprogramming Batch System:

Multiprogramming was started to overcome the problem of underutilization of CPUs and main memory. Multiprogramming is interfered in the execution of multiple jobs by a single computer.

3. Multiprocessor System

The main purpose of Multiprocessing is two or more central processing units within a single computer system. The term refers to the ability of a system to support more than one processor or assign tasks to them.

4. Desktop System:

Desktop operating system is known as “Client Operating System”. Desktop operating system is installed in the user’s machine such as (desktop, laptop or notepad), and it provides the environment in between the users and hardware, due to that environment users can control the entire local machine as well as their peripheral.
Examples are – Microsoft Windows, Linux, Unix, Mac, Android, Ubuntu, IOS, and more..

5. Distributed Operating System:

The distributed operating system is a model where distributed apps are running on many computers connected through communication. A distributed operating system is an extension of the network operating system that supports high levels of communication and integration of machines on the network.

6. Clustered System:

A package system uses several CPUs to accomplish a task. It is different from the parallel system in the package system, in which two or more separate systems are tied together. Clustered computers share the storage and are connected closely through LAN networking.
Clustering is usually done to provide high availability. A layer of cluster software runs on the cluster nodes. Each node can monitor one or more nodes on the LAN.

7. Real Time Operating System:

Purpose of operating system (OS) is responsible for managing the computer’s hardware resources and hosting applications running on the computer. Real Time Operating System is designed specifically for such applications, which are run 24*7 days without human interference. This can be particularly important in measurement and automation systems, where downtime is expensive or delay in program security can be a threat.

8. Handheld Operating System:

Handheld operating systems are small tools that do basic tasks like email, web browsing and scheduling.
