What is AI?

Artificial Intelligence (AI) refers to the simulation of human intelligence in machines that are programmed to think and learn like humans. It is a branch of computer science that aims to create intelligent machines capable of performing tasks that typically require human intelligence. AI uses algorithms and data to mimic human cognitive functions such as learning, problem-solving, and decision-making.

Definition of AI

AI is a field of study that encompasses various techniques and approaches to create intelligent systems. It involves the development of algorithms and models that enable machines to perceive, reason, and act in ways that imitate human intelligence. AI can be classified into different categories based on the level of intelligence exhibited by the machines, ranging from narrow AI to general AI and superintelligent AI.

AI vs. Human Intelligence

While AI aims to replicate human intelligence, there are fundamental differences between AI and human intelligence. Human intelligence is highly flexible, adaptable, and capable of understanding complex concepts without explicit instructions. On the other hand, AI relies on predefined rules, algorithms, and data to perform tasks. While AI can surpass human capabilities in specific domains, human intelligence remains superior in terms of creativity, emotional intelligence, and abstract thinking.

Examples of AI in Everyday Life

AI has become an integral part of our daily lives, even if we may not always realize it.
