Artificial Intelligence (AI) refers to the simulation of human intelligence in machines that are designed to think and act like humans. The term "artificial" denotes that this thinking is not a natural process, but rather one created by programming algorithms into computers or other devices. AI systems can perform tasks such as recognizing speech, learning from experience, solving complex problems, understanding human language, translating between languages, driving cars, and even creating artworks.

AI technology has evolved significantly over the years with advancements in machine learning (ML) algorithms that enable machines to learn from data without being explicitly programmed for every task they perform. This field of AI is often divided into two main categories: narrow or weak AI, which is designed and trained for a specific task such as recognizing faces or driving cars; and general or strong AI, an advanced form of artificial intelligence that has the ability to apply intelligence across any problem domain, much like human intelligence.

The development of Artificial General Intelligence (AGI) remains one of the most significant challenges in computer science today as it would require machines with cognitive abilities equivalent or superior to humans and could potentially lead to a transformative impact on society if achieved successfully.
