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 device", "The main components of the party met to choose the next candidate", "The antisocial components must be re-educated and integrated into the community", "I need other components to complete this work".
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 metallic, ceramic or plastic material. Typically, these components are interconnected by soldering to the printed circuit.
There are several types of electronic components: the discrete components are encapsulated one by one (such as transistors or diodes), while the integrated components form more complex assemblies from the union of discrete components.
Other types of components are the active ones (they generate an electrical excitation), the passive ones (they are in charge of the connection of the active components), the electromagnetic ones (transformers, inductors), the electroacoustic ones (microphones, headphones) and the optoelectronics (LED diodes).
The semiconductor components, finally, are those manufactured with semiconductor materials (that conduct or isolate the electricity according to the temperature of the environment) such 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 as synonyms.
Component video is known as the signal that has been divided into two or more component 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 information into a single signal; as well as the first, it requires other cables for audio transmission.
Playing a video signal on a device such as a monitor or a television is a relatively simple and direct process, which is complicated by the great variety of sources. Computers, DVD players and video game consoles, for example, store, process and transmit video signals using different methods, and usually each device offers its users more than one type of video connection.
One option to maintain the clarity of the signal is to separate it into video components, so that they do not interfere with each other. A separate signal 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 (name that is usually given to the connecting cable). a computer to an analog monitor) and YPbPr (used by DVD players and video game consoles).
While the discussion between digital video advocates and those who argue that analogue continues to offer more advantages has not yet come to an end, it is not incorrect to say that those who have adopted digital video by component are those who especially appreciate color quality. and the resolution of the image, while users of analog cables do not give such importance to the results.
Finally, among the signals that can transmit a cable of this type are the 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 exceed it by 16 times.
