From Latin nucleus, the term nucleus It has different uses and meanings. It could be said that it is the component main or essential of something , to which other elements are added or coupled to form a whole or a set.
It is also known as the core of the dimension or the central issue of a thing , either physical or symbolic. For example: “The core of the matter is the redistribution of income”, "Let's go to the heart of the problem: how many people are trapped?", "To support the structure, it is necessary to prop up its core".
Core, on the other hand, is the mollar zone of those fruits that have a hard shell and the bone or stone of fruits
In another sense, the core of the group or society of individuals who meet to have something in common ("The Buenos Aires core manifested against the adjustment") and at set of houses and buildings with its inhabitants ("The urban center experiences a marked increase in unemployment").
In biology , he cell nucleus It is the part of eukaryotic cells that houses a lot of genetic information. It is organized in chromosomes and accompanied by protein .
In physical , he atomic nucleus It is the center of a atom . It is made up of neutrons and protons that develop what is known as a strong nuclear interaction .
He syntactic core , on the other hand, is a linguistic concept that allows naming the term or morpheme that is responsible for determining the grammar characteristics and the syntax of the syntagma .
In the case of the sun, the nucleus represents its region central, which represents a fifth of its total radius, about 139 thousand kilometers. It is in this same area where the thermonuclear reactions that generate all the energy produced by this star take place. It is made up of 49 percent hydrogen, 49 percent helium and the rest is divided between catalyst components. The temperature of the solar core, whose equilibrium is achieved by the energy generated by its own transformations, is around 15 million kelvins (unit whose absolute zero is the point at which all thermal activity stops).
We can point out, finally, that in the computing , the core (also known as kernel ) is the main part of OS .
Also, computer processors and other devices, such as consoles and tablets, usually have more than one core, which multiplies their theoretical performance. Given the characteristics of the electrical circuits, the maximum speed has found a ceiling that has not been able to overcome considerably in recent years. To compensate for this impossibility due to the type of technology used, the presence of several brains That tasks are divided seems to have been the smartest answer.
However, not all developers have chosen to optimize their applications to take advantage of that advantage. The same phenomenon occurs with respect to 64-bit processors. As a result, it is often observed that the efficiency of a program does not vary according to the number of cores; there may even be the case of a inversely proportional performance.
A good example of the correct use of multiple cores is Blender, the world's most famous open source 3D editor. When rendering (in this case, the process by which each of the numerous frames that make up a movie is created) an animation with that tool, the difference between the use of a processor or another is so clear that it is hard to imagine a more graphic example : The speed at which the image sequence is exported is directly proportional to the number of cores.
