The word source is defined as everything that is the origin of something else, or from which its cause arises. It is a term that has many definitions, depending on the context where it is used. For example, in the field of physics there is the energy source, in the typographic context there is the font (letter), in electricity there is the electrical source, etc.
Below are a series of definitions where the source word is the main element:
source of energy: if the field of physics or chemistry is studied, this term will arise, the source of energy represents all those natural components that man uses to produce the necessary force that allows industrial activity. These are classified as primary and secondary.
Primary sources, also called renewable sources, are those whose reserves do not diminish with their exploitation, for example rivers, wind, sun. As can be seen, this class of primary sources can be found anywhere in the world, and its importance is increasing every day, as it is a fundamental part of world energy production.
Secondary energy sources, also called non-renewable, are those that currently comprise most of the world's energy demand; Its extraction and production has the most modern technologies, however it can have a negative impact on the environment. Some of this source are coal, oil, natural gas, among others.
font (letter): this type of font is found in the field of digital typography, which consists of a set of alphanumeric characters that are distinguished from the others by their design and characteristics; These can include only letters, numbers or special characters, with specifications according to their position and structure. The letters are classified according to their morphology, historical evolution, function, character. Some of them are:
Text letters are the most frequently used, as they are ideal for continuous reading, while decorative letters have
a more expressive function, they are used to give contrast and diversity to a particular element.
Each letter has a fundamental basic design, which are grouped into categories that distinguish them from the elementary model, which in text letters are usually round. The most used are: italics, “bold”, etc.
Electrical source: in electricity, the element that has the ability to produce a potential difference between its edges is called a source so that it supplies electrical current for other circuits to work. The electrical source is classified into real source and ideal source.
The ideal source is used in circuit theory for the study and creation of models that allow the study of the behavior of electronic components. The real sources differ from the ideal ones, when the ddp (potential difference) they produce are subject to the load to which they are connected.
power supply: in electronics, this term is used to define the instrument that changes the alternating current into one or more direct currents, which are used to operate different electronic devices, such as the television, the computer, etc. the power supply to meet certain phases that allow efficient operation, some of them are: transformation, rectification, filtering and stabilization.
information sources: they are important tools for the knowledge, access and search of information. Its main function is to investigate, fix, and issue the source of the information contained in any physical medium. They are classified into primary and secondary sources.
The primary sources are those that contain information of origin, that is to say that in them are the original data of the news, which does not need to be completed with another source. For their part, secondary sources are those whose main purpose is not to offer information, but to indicate the document or source that can provide it, making reference to original primary writings.
The source code in computing is defined as the set of lines of texts that represent the guidelines that the computer must follow to develop a program, that is to say that the operation of the computer is written in this code.
