What is the Operating System, What Does it Do? How Does the Operating System Work, What are its Types?

Technological devices such as computers, tablets and smartphones that we use during the day have operating systems. The operating system installed after computer production can be deleted if desired. Once deleted, it can be reinstalled or even replaced with another operating system.

What is an Operating System?

One of the frequently asked questions is what is the operating system? Programs running on computers, from large to small, need an operating system. Therefore, before running the programs in the computer, the programs must be placed in the main memory with the help of the operating system. This is usually done automatically at the first startup stage of the computer, the operating system in HHD is loaded into RAM. What is expected from an operating system is that the hardware and software resources work together and properly.

If we look at the history of operating systems; British mathematicians designed the first real computer. However, in those years, the operating system was not available due to insufficient technology. 1.4.1. There was not much improvement in First Generation Operating Systems until World War II. However, in the 1940s, some digital machines were developed with the work of researchers at Harvard University and Princeton University and other researchers in the United States and Germany. Vacuum tubes were used in the construction of these digital machines. However, these machines were very large and operated much slower than today's computers. Those who designed, manufactured, programmed, operated and maintained the machine at that time were the same people. No such thing as an operating system was known. Later, card machines started to develop in the 1950s. Programs were written on cards and read. In the following years, Second Generation, Third Generation and Fourth Generation Operating Systems were developed.

What Does an Operating System Do?

The question of what operating systems do is wondered by many users. Application codes are maintained by the hardware. However, it is an intermediary between the computer and the programs required for functions such as memory allocation, input / output. It is among the tasks of the operating system to gain access to the computer's file system, to allocate enough system resources for too many programs running at the same time, and to help not conflict with each other.

Let's take a general look at the tasks of the operating system:

Provides communication between the environment and programs

Creates a file management system to organize and access files on storage devices

Provides data communication between programs

Provides secure access to resources in multi-user systems

Managing the system memory, providing facilities such as disk buffering and ensuring that memory works effectively

Help the user run programs, enable the user to issue commands

How Does the Operating System Work?

The operating system starts working as soon as the computer is turned on. It deals with the project software being worked on. It works in a certain order.

There are some points to note for the operating system:

When buying a computer, it should be paid attention to whether the operating system is installed or not. The best operating system for the computer is Windows. All software on the market is suitable for Windows operating system.

To answer the question of how the operating system works, we use the small symbols under the 'All Programs' option in the 'Start' menu. For example, the symbol for the Paint program is a jar with drawing pencils. Word processing programs are symbolized by a written notebook page.

Operating System Types

The best known operating system is Windows. There are many operating systems variants including Amiga, Pardus, Chromium, Linux, Unix, MacOs and Android. The operating system is present in many electronic devices, including computers. Let's get brief information about the most used operating systems.

Windows Operating System

It was developed by the Microsoft company. It is the most used operating system in the world.

Amiga Operating System

It is the operating system used in personal computers. Amigaos has maximum performance. It is equipped and flexible.

Chromium Operating System

It was designed by Google Chrome. It has a unique interface. It is useful and very reliable.

Android Operating System

It is based on Linux. It is a system developed for mobile device and phone. It is open code. Therefore, it is suitable for development.
