In computing, input and output devices are the means by which the user communicates with the information processing system, such as tablets, computers, or smart phones.
In computing, input devices and output are also called peripheral, since they are not an integral part of the computer system itself, but peripheral elements that connect to the system through its inlet slots ( inputs ) or output slots ( outputs ).
See also Output .
The input and output peripherals are connected to the information processing systems through expansion slots or input and output connectors that are integrated into your motherboard, such as USB slots or ports, LAN connector, connector VGA or audio connector.
See also USB .
The input devices are those elements that are connected to enter the desired function or information into the general system. Some examples of input devices are: the keyboard, the mouse, the scanner.

The output devices are those items that are connected so that the processing system exposes the desired function or information. Some examples of output devices are: the monitor, the portable memories, the printers.
Solar energy is one that is obtained from solar radiation that comes to Earth in the form of light, heat or ultraviolet rays. It is a type of clean and renewable energy, because its source, the Sun, is an unlimited resource.Solar energy
To transform solar energy into electrical energy, the electromagnetic radiation from the Sun is collected by different means (thermal collectors, photovoltaic cells, etc.).
Solar energy can be used in two ways: by means of thermal conversion , which consists of transforming solar energy into thermal energy, and photovoltaic conversion , in which solar panels are used to collect light energy and convert it into electricity.
The energy from the Sun has been used by humans since ancient times in multiple ways. An example of this is the use of the Sun as a source of heat to dry clothes.
Solar energy is important for the planet because it is a renewable energy resource that could reduce our dependence on highly polluting fossil fuels. In addition, it helps sustainable development, reduces pollution and reduces environmental impact.

Passive and active solar energy
Solar energy can be classified as passive or active, depending on how it is captured, converted and used.
Active solar energy : uses photovoltaic panels and solar thermal collectors to collect energy.
Passive solar energy : essentially uses bioclimatic architecture, specially designed to capture and take advantage of solar energy.
Types of solar energy
Photovoltaic Solar Energy
Photovoltaic solar energy is one that takes advantage of solar radiation to make its transformation into electricity. It uses semiconductor panels. It is the most developed solar energy source today.
Thermal solar energy
Solar thermal or thermosolar energy is one that takes advantage of the heat of the Sun to produce hot water for domestic consumption (cooking, heating, sanitary use, etc.).
Concentrating solar energy
Concentrating solar energy is a kind of solar thermal energy that uses mirrors to concentrate sunlight over a small space. Concentrated sunlight is transformed into heat, from which electricity is generated.
Hybrid solar power
It is called hybrid solar energy that conjugates two sources of energy to produce electricity from a hybridization. For example, photovoltaic solar energy with fossil fuels.
Solar wind power
As solar wind energy is known that uses the air heated by the sun to produce electricity.
Solar energy: advantages and disadvantages
Solar energy has many positive aspects at present, where it is increasingly necessary to supply the use of non-renewable fossil fuels for energy generation.
Among its advantages , solar energy is renewable and therefore is non - polluting.
Among its disadvantages is the fact that it is a source of energy dependent on factors such as the climate or the number of hours of the Sun per year.
