Answer:
4. Command line interface (CLI)
Explanation:
An operating system is a system software pre-installed on a computing device to manage or control software application, computer hardware and user processes.
This ultimately implies that, an operating system acts as an interface or intermediary between the computer end user and the hardware portion of the computer system (computer hardware) in the processing and execution of instructions.
Some examples of an operating system on computers are QNX, Linux, OpenVMS, MacOS, Microsoft windows, IBM, Solaris, VM etc.
A Command line interface (CLI) refers to a text-based user interface that allow users to operate a software application or program, as well as manage and execute operating system functions by typing standard line of commands into the text-based user interface with a real-time response.
Basically, the CLI is solely text-based and as such requires a thorough knowledge and understanding of global commands, as well as administrative privileges in some cases.
<em>Hence, the operating system function which has a steeper learning curve (more difficult to learn) and can potentially break the system without careful use of its operations is the Command line interface (CLI). </em>
- Mediante la tecnología se han implementado el uso de medios de transporte como los "coches verdes" o eléctricos que contribuyen a disminuir la producción de gases contaminantes atmosféricos.
A través de la ciencia y la biotecnología se ha avanzado en el campo de la purificación del aire algunas de las herramientas que actualmente se están utilizando son:
- La biofiltraccion del aire que se realiza a través de macroporos de material filtrante por donde se filtran los compuestos orgánicos e inorgánicos atmosféricos. También es posible realizar la biodepuracion del aire con plantas purificantes y ornamentales.
- El uso de las paredes arbóreas cubiertas de musgo ha permitido que en algunas ciudades como París y Berlín mejore la calidad del aire,ya que el musgo se caracteriza por su gran capacidad para filtrar contaminantes del aire como las partículas y los óxidos de nitrógeno ya que los convierte en purificadores naturales ideales para el medio ambiente.
Lo anterior son algunos de los grandes avances que ha tenido la ciencia y la tecnología para lograr mejorar la calidad del aire y por consiguiente la calidad de vida de las personas.
