What are the types of Operating System​
Archy [21]

Answer:

1. Gestión de la memoria principal

Esta es una característica del sistema operativo básica. La memoria principal de la computadora almacena los datos que serán usados por el CPU en la ejecución de los programas. El sistema operativo se encarga de gestionarla, es decir, asignar partes de memoria a la nueva información usada, y evitar que se sature.

2. Gestión de la memoria secundaria

Es la memoria más “permanente” de una computadora. Al igual que la memoria principal, el SO sistema operativo asigna el orden de guardado en esta memoria y la mejor manera de aprovechar el espacio libre.  

3. Gestión de procesos

Cuando envías un comando para que el ordenador realice una tarea, una de las funciones del sistema operativo es organizar los recursos de la computadora para ejecutarla. Esto incluye la memoria, el tiempo del CPU, los programas y archivos necesarios para ejecutar la tarea, los procesos que podrían entorpecerla y los periféricos que podrían ser necesarios para cumplirla.

4. Gestión de recursos  

¡Esta es una de las características del sistema operativo más importantes! El sistema operativo coordina los recursos del hardware que integra la computadora para cumplir con las tareas requeridas. El CPU, los periféricos, las memorias principal y secundaria, los programas, todo tiene que trabajar al unísono para cumplir con las tareas de forma óptima.

5. Gestión de usuarios  

El software operativo controla el acceso de los usuarios a las cuentas individuales o grupales. También, se encarga de administrar a qué recursos e información tiene acceso cada uno de ellos.  

6. Gestión de la seguridad  

Así como controla el acceso de usuarios, el sistema operativo también está encargado de gestionar los controles de seguridad de la computadora, entre ellos el firewall. Por ejemplo, en cuanto a la función del sistema operativo para la seguridad informática es evitar la pérdida de datos, controlar la confidencialidad de los datos y controlar el acceso a la información y a los recursos del equipo.
