Para que funcionen los otros programas, cada ordenador de uso general debe tener un sistema operativo. Los sistemas operativos realizan tareas básicas, tales como reconocimiento de la conexión del teclado, enviar la información a la pantalla, no perder de vista archivos y directorios en el disco, y controlar los dispositivos periféricos tales como impresoras, escáner...</span>también es el software (la parte virtual de la computadora) que administra al hardware ( lo físico de la computadora ).</span><br />
<span class="Apple-style-span" style="background-color: #666666; color: white; font-family: Georgia, 'Times New Roman', serif;">Los drivers son los controladores de los dispositivos ( de entrada ,salida , y de los dos a la vez ).</span><br />
