Operating System

Operating system

 

   In our life, we daily use several digital devices and everyone used. Hardly, a person who is not aware of any digital devices. A digital device like form digital watch to a cell phone. Every digital device required an operating system. A driver required to drive a bus, similarly an operating system required to operate every digital device. without an operating system, digital devices are useless. Because it must require an OS.

"Operating System is just a magical line between user and hardware component of any digital device."

An Operating System is a program code that controls the hardware component and function of the device. An Os is system software that acts as an interface between the user and computer hardware. The main purpose of the operating system is to provide a platform where user can perform their task in a more efficient way In simple words when the booting process is completed then the next phase seen by the user is known as an Operating System. Operating System is also responsible for allocating the resources to the system. Modern Operating System is GUI based which is a Graphical User Interface. GUI allowed users to view icon, click through the mouse, and graphical text. GUI of every operating system looks different.

Types of Operating System

            The operating system is basically classified on the basis of their working performances. All the operating system is designed for a special purpose like server, desktop, mobile, etc.

Batch Operating system:

            In Batch Operating System job pool created of similar types of jobs which are executed by os system one by one. Ex:-MS-DOS.

Multiprogramming Operating System:

                            In Multiprogramming operating system number of the program of different users executed one by one by the system or we can say CPU. In this type of operating system, the CPU has no time to remain idle. CPU is always busy due to  number of programs to execute. Ex:- Unix, Windows.

Multitasking Operating System:

                         In a multitasking operating system, CPU performs multiple tasks of single users by switching on them one by one. Ex:-Unix, windows, mac os, etc.

Multiprocessing Operating system:

            In this system operating system, the system contains two or more processors, so that the system executes several programs/tasks at the same time.

Time-sharing  Operating System:

                            In the time-sharing operating system, the number of users can access the system on a scheduling basis. In this type of Operating System many terminals connected to the same system. A short period of CPU's time is allocated to every user's program executions.

Distributed Operating System:

                                In this type of operating system, the workload is distributed into two or more computer that is linked by a communication network.

Real-time Operating System:

                            In a real-time operating system, it is compulsory to perform the given tasks within its given time The main factor affecting this system is the accuracy. Accuracy of the system does not depend on the logic correctness and computation but also upon the time at which the executed. Ex:- Robotics, air-traffic, rocket.

Some of the most common used Operating System:

                            Generally, people are used preloaded os ie. the os comes with computers when they purchase it. but they can upgrade it later or can be changed later. The most commonly used Operating system is used in our country that is listed below.

• BOSS
• WINDOWS
• LINUX
• MAC OS
• IOS
• ANDROID etc

            It is one of the most expensive Operating System created by Apple. It is available preloaded with Macintosh computers. It is also available in a different version ie. Sierra, high sierra, etc. The number of users of macOS is much lower than the number of users of the window.

Ios: 

     It is also developed by Apple, It is run on an Apple mobile phone, it is also called apple's mobile operating system, Ios is also expensive like macOS. it is run on iPhone, iPad, iPod touch devices, etc. The different thing in which is, it supports the objective-c,c,c++ and other swift programming languages.

Android:

        Android is an open-source Linux based operating system for mobile phones, smartphones, tablets, etc. The android operating system is designed by Google and Nowadays It is a mostly used operating system on smartphones. The most recent version of android is Android10 released in September 2019.
