2. knowledge about the environment
3. choosing the right percept sequence
4. action that performed

## Omniscient Agent

omniscient agent is like rational agent but it knows the result or outcome of the action it performed.

## Learning Agent

Rational Agent and omniscient agent doesnot operate in unknown environment.But Learning agent can operate in unknown environment.It will perform the action without knowing that will right or wrong and the outcome of the action will be learned and stored in the knowledge base.

## Autonomous Agent

The agent operates based on the knowledge given by the designer is  not a autonomous agent.Agent is called autonomous agent when it automatically learn from the environment based upon the knowledge learned it will take decision and action.
