Informatics is the applied science that covers the study and application of automatic data processing, electronic devices and computer systems. It is also defined as the automatic processing of information.Accordingly, computer systems must perform the following three basic tasks:
* Input: Collection of digital information.
* Process: Data processing.
* Output: Transmission of binary outcomes.
At the beginning of information processing, to data provided only repetitive and monotonous work of the administrative area, through automation of these processes, it resulted directly reduced costs and increased production. In computing converge the fundamentals of computer science, programming and methodologies for software development, computer architecture, computer networks, artificial intelligence and certain issues related to electronics. It can be understood by computing the synergistic union of this whole set of disciplines. This discipline applies to many and varied areas of knowledge or human activity such as: business management, storage and retrieval of information, monitoring and process control, industrial robotics, communications, control, transport, research, development games, computer design, applications / multimedia, medicine, biology, physics, chemistry, meteorology, engineering, art, etc.. One of the most important applications of computing is to provide information in a timely and accurate, which, for example, can both facilitate decision making at the management level (in a company) and allow monitoring of critical processes. Currently it is difficult to use an area that somehow, the support of information technology. This can cover a huge range of functions, ranging from simple domestic issues, even the most complex scientific computations.
The main functions of the computer are the following:
* Creation of new job specifications.
* Development and implementation of computer systems.
* Systematization of process.
* Optimizing existing computer systems and methods.
