The operating system of a computer is the vital element to work. Without SO, we cannot perform any tasks, which the PC pas to be just a decorative object. Such is the importance of the operating system.
As we know, there are several on the market OS: Linux, Windows, Mac, Android and many more, but these are their trade names. The important thing is what kind of operating system corresponds each. This is the aim of this article.
Today, there are 4 basic types of operating systems. They are divided into groups related to the type of computers that control and the type of applications that execute.
These are the broad categories:
RTOS Real-Time Operating System
It is used to control machinery, scientific instruments and industrial systems. Generally an RTOS has a very simple interface for the user and is not intended for the end user, since the system is delivered as a “sealed box”.
The RTOS function is to control the computer resources for a specific operation, such as execute the same instruction or operation during a determinate time period. In a complex machine, if one part moves faster, because there are resources available to do system, it can be catastrophic.
This operating system was developed for a single user can do one thing at a time. Some operating systems used by cell phones are the best example of a modern single-user and single-tasking operating system.
This type of operating system is the most widely used in desktop computers and notebooks. The Microsoft Windows and Apple MacOS platforms are examples of operating systems that allow a single user to use several programs simultaneously. For example, it is perfectly possible for a Windows user to write a note in a word processor while performing a download of a file, or printing a email.
A multiuser operating system allows multiple users to use the computer’s resources simultaneously. The operating system must ensure that applications for multiple users are balanced. Each of the programs used must have sufficient and separate resources so that a user with problems does not affect to the other users. Unix, Windows Server, VMS and mainframe operating systems like MVS are examples of multi-user operating systems.
It is important to differentiate the multiuser operating systems that support single-user operating systems networks. Some versions of Windows can support multiple users on a network, but the operating systems themselves are not true multi-user systems. The system administrator is the only “user”. The network supports and all remote users are, from the standpoint of the operating system, a program being executed by the administrator.
You need to do an operating system?
The aim of an operating system is to make that the computer and its peripherals can be used without problems for anyone, even without knowledge of the hardware available on that computer.
It has to enable the user to create and access files, use the programs, enter internet, play and all things that can be done with computers or mobile devices. Besides that, the operating system has to execute the software and provide access to the system resources to user in a simple and organized way.
What is the most used operating system?
Undoubtedly, Windows, the operating system of Microsoft, is the most widely used. It is present in over 90% of the world’s computers.
