What is an Operative System

An operating system is software responsible for managing and coordinating the basic operation of various applications, hardware and other resources used by the user on a computerhence its importance is highlighted.

The operating system performs important and different tasks such as transmitting information between application programs, controlling the operation of peripheral devices (printers, keyboards, etc.), avoiding security problems in certain programs, among others.

This is possible because they are made to offer software on which other programs can work, hence it is the applications, programs or peripheral devices that must be programmed to work correctly in operating systems.

In this sense, depending on the type of operating system selected for the computer, it will be possible to use certain applications or programs. Among the most used are Microsoft Windows, DOS, Linux, Android and iOS.

In general, these systems offer the user a representation or graphical interface of the processes they carry out, a command line or instructions, window managers, among others, that are practical to use.

The term operating system comes from the English operating systemand in Spanish it is sometimes indicated with the acronym ‘SO’.

Types of operating systems

Operating systems have been created so that the user can make easy and correct use of the various programs and hardware used in the computer. Below are the different types of most used operating systems.

Graphic environment operating system

A graphical environment operating system is based on images and icons. It is characterized by having a more intuitive character for the user through the use of written language and images.

It allows you to carry out tasks such as opening files or accessing applications in a simple way without the need to write commands. An example is the Windows XP operating system.

It is the most used type of operating system due to its characteristics. It differs from command line operating systems like MS-DOS, which are command-driven and text-based.

Android operating system

Android is a type of Linux-based open source operating system owned by Google Inc., and was originally developed for mobile devices.

It uses a variant of Java and provides a series of interfaces to develop application programs and access to the different functions of the mobile device.

Windows operating system

Microsoft Windows operating systems make up a family of operating systems that are developed by the Microsoft Corporation based on the use of icons called ‘windows’.

It is one of the most used and popular operating systems worldwide. It has different versions (such as Windows 95 and Windows Vista) and comes with a set of applications.

Ubuntu operating system

The Ubuntu operating system is the name of free and open source software that uses a Linux kernel or kernel and is developed by the company Canonical Ltd. and the Ubuntu Foundation.

The name of ubuntu It is a term from the African Zulu and Xhosa languages, which refers to solidarity between human beings.

Examples of operating systems

There are different examples of systems that have different versions that have different features and functions:

  • Microsoft Windows: is one of the best known graphical interface and software tools.
  • Linux: It is one of the operating systems highlighted for developing free software.
  • Mac OSX: It is the Machintosh operating system, based on Unix and that is installed on Apple brand computers.
  • Android: Works on mobile devices with touch screens, and is based on Linux.
  • MS-DOS (Microsoft Disk Operating System): in Spanish MicroSoft Disk Operating System, was one of the most prominent operating systems in the 1980s characterized by displaying its commands on a screen with a dark background.
  • UNIX: Created in 1969 with multitasking and multiuser functions.

Operating system features

The main functions of the operating system are intended to manage the various resources that the computer has, among which the following stand out:

  • Coordinate the operation of the hardware.
  • Manage the main memory of the computer.
  • Manage information storage processes.
  • Organize and manage files and documents.
  • Manage the computer programming algorithm.
  • Run various applications.
  • Through the drivers, it manages the input and output of peripheral devices.
  • Coordinates routines for device control.
  • Inform about the state in which the computer system is found, that is, how the tasks are executed.
  • Maintain the security and integrity of the system and computer.
  • Establish the communication processes of the different components and applications of the computer.
  • Manage the profiles of the users who have the computer.

Classification of the operating systems

Operating systems are classified as follows:

  • single task: You can only run one task or program at a time. These are the older operating systems.
  • single user: It is the operating system that can only respond to one user at a time.
  • Multitask: are those that allow several programs to run at the same time on one or more computers.
  • multiprocessor: makes it possible for the same program to be used on more than one computer.
  • multiuser: Allows more than two users to access the services and processing of an operating system at the same time.
  • Real time: are the operating systems that work in real time to users.

Operating system features

Among the main characteristics of operating systems, the following stand out:

  • All computers have an operating system for proper operation.
  • Its main function is to plan the tasks that are executed by the computer system.
  • You must effectively manage and supervise the operation of the programs and hardware that have been installed on the computer.
  • It allows to execute new functions in the computer.
  • It can fulfill multiple tasks.
  • It allows efficient use of devices and other computer resources.
  • Through the algorithms it uses, it makes it possible for the use and operation of the computer or device to be efficient.
  • It provides the connection between software, hardware and the user interface.
