The term computing It has its origin in the Latin word computatio. This word allows to address the notion of computation as account or calculation , but is usually used as a synonym for computing (from French informatique). In this way, it can be said that computing nuclei at scientific knowledge and methods .
These automated information systems are achieved through certain tools that have been created for that purpose, computers or computers .
The origin of computing, experts say, goes back more than three hundred years ago, when machinery focused on various calculation tasks began to be developed. In 1623 , Wilhelm schickard invented the first mechanical calculator .
However, computers capable of performing multiple processes (that is, they were not limited to mathematical calculations) began to emerge in the 1940s. The massive and domestic use of these machines would arrive only in the '80s, with the production of personal computers or PC . The end of the 20th century, with the rise of Internet , represented a new impulse for everything related to computer's science .
Refering to computer theory , it must be said that it is considered as a science focused on the study and formal definition of computations. This discipline defines the computation as the product of a solution or an outcome, especially in the mathematical / arithmetic sense of the concept, using a process or algorithm.
In other words, computing is the science that studies and systematizes the orders and activities dictated in a machine, analyzing the factors that participate in this process, among which are the programming languages, which allow generating a list of data neat and understandable for the machine.
In the process two types of analysis are carried out, an organic one (translation of the indications into a language understandable by the computer) and a functional one (collecting the information available in the process of automating).
To talk about computing, it is necessary to define the concept of algorithm . An algorithm is a set of certain steps that are structured over time that respond to a list of clear rules and that aim to solve a particular problem. They must meet certain conditions: be defined (Of course, detail each of the necessary steps to perform without ambiguities), finite (the actions that comprise it must be concluded logically and clearly), have zero or more entries and with one or more exits , And be cash (Use exactly what is required to solve the problem, spending the minimum amount of resources and being able to execute effectively).
Other areas that computing also includes are artificial intelligence linked to computers, graphic and network computing, database systems, computer mathematics and different types of engineering Related to this machine.
At present, the development of computing and technologies related has allowed the development of various types of documents, the sending and receipt of email , the creation of digital drawings, audio editing and book printing, among many other processes.
It should be noted that the technology used in computing is microelectronic type with components physicists (processor, memory, etc.) and logical (operating system and programs).
