There are many concepts about Artificial Intelligence. Some definitions say that is the study and develops intelligent machines and software. Other definitions say that is the study and design of intelligent agents.

Intelligent agent is a computational personage that acts according to definite script, indirectly or directly by a user. It is a real or virtual entity, able to act in an environment, communicating with another agent that it is moved by a set functions that want to achieve. The agent have own resources and this allows the agent perceive the environment. These resources are sensors such as temperature, pressure, humidity, etc. Other resources can be typed data by user in front of computer. It depends if it is a real or virtual agent. This can be explained in the figure 1.

The agent can be, eventually, reproducing. This behavior tends to reach the goals. In this case some design use neural networks to predict the solution of the problem and genetic algorithms to obtain the best solution. These are shown in the figures 2 and 3.

There are many applications that use intelligent agent and we can quote: Information control, manages networks, mobile access, electronic message, etc.

Summarizing, the artificial intelligence can get with the applications of the intelligent agent on all devices that have processors chip.
