Component is that which is part of the composition of a whole. These are elements that, through some type of association or contiguity, give rise to a uniform set. For example: “A small motor, a clock and an electronic mechanism are the components of this apparatus”, “The main components of the party met to elect the next candidate”, “The antisocial components must be reeducated and integrated into the community”, “I need other components to finish this job. “
An electronic component is a device that is considered a constituent part of an electronic circuit. It usually ends in two metal pins and is encapsulated in a metal, ceramic or plastic material. Typically, these components are interconnected by soldering to the printed circuit.
There are several types of electronic components: discrete components are encapsulated one by one (such as transistors or diodes), while integrated components form more complex assemblies from the union of discrete components.
Other types of components are active (generate electrical excitation), passive (are responsible for connecting the active components), electromagnetic (transformers, inductors), electroacoustic (microphones, headphones) and optoelectronics (LEDs) .
According to DigoPaul, the semiconductor components, finally, are those made from semiconducting materials (leading or isolate the power according to the temperature of the atmosphere) as silicon.
In the case of electronic circuits, it is important to distinguish between components (physical devices) and elements (abstractions or models). In other circumstances, components and elements can be used synonymously.
It is known as video component to the signal that has been divided into two or more components channels. In short, it refers to a type of analog video information that is transmitted or stored in three different signals and is usually associated with cables with three connectors: one red, one green and one blue. A more popular alternative is composite video (whose connector is yellow), which combines all the information into a single signal; as well as the first, it requires other cables for the audio transmission.
Playing a video signal on a device such as a monitor or television is a relatively simple and straightforward process, which is complicated by the wide variety of sources. Computers, DVD players, and video game consoles, for example, store, process, and transmit video signals using different methods, and each device generally offers its users more than one type of video connection.
One option to maintain signal clarity is to separate it into video components so that they do not interfere with each other. A signal separated in this way is known as “component video”, and some of the most popular examples are S-Video (super video, usually associated with VHS players), RGB (a name often given to the cable that connects a computer to an analog monitor) and YPbPr (used by DVD players and video game consoles).
While the discussion between advocates of digital video and those who argue that analog continues to offer more benefits is not yet over, it is not wrong to say that those who have embraced component digital video are generally those who particularly appreciate color quality. and image resolution, while analog cable users do not attach much importance to results.
Finally, among the signals that a cable of this type can transmit are the well-known 480p, 720p and 1080p. The market trend is slowly saying goodbye to the current high definition (1920 x 1080, or 1080p) to enter the era of ultra-high definition, which will surpass it by 16 times.
