Concept of Artificial Intelligence

Artificial Intelligence refers to the simulation of human intelligence processes by machines, particularly computer systems. These processes include learning (the acquisition of information and rules for using it), reasoning (the ability to apply rules to reach approximate or definite conclusions), and self-correction. AI systems are designed to perform tasks that would normally require human intelligence, such as understanding natural language, recognizing patterns, solving problems, and making decisions.

The concept of AI can be divided into two broad categories:

Narrow AI (Weak AI): This refers to AI systems that are designed and trained for specific tasks, such as voice assistants like Siri or Alexa, recommendation systems on streaming platforms, or self-driving car technology. Narrow AI excels at the tasks for which it is designed but lacks general intelligence.
General AI (Strong AI): This represents a more advanced form of AI that has the ability to understand, learn, and apply knowledge across a broad range of tasks, similar to human cognitive abilities. While general AI remains largely theoretical and is a subject of ongoing research, its development could revolutionize multiple industries.
