Artificial Intelligence (AI) refers to the area of computer science focused on creating systems or machines that can perform tasks that typically require human intelligence. This encompasses a wide range of technologies and applications, including but not limited to, understanding natural language, recognizing patterns in data, making decisions, solving problems, and learning from experience.

AI can be categorized into two main types: narrow AI and general AI. Narrow AI, also known as weak AI, is designed to handle specific tasks, such as virtual assistants, recommendation systems, or image recognition software. In contrast, general AI, or strong AI, would possess the ability to understand, learn, and apply intelligence across diverse tasks at a level comparable to that of a human being. However, general AI remains largely theoretical and has not been achieved yet.

AI systems utilize various methods such as Machine Learning, where algorithms are trained on large datasets to identify patterns and make predictions, and Deep Learning, a subset of Machine Learning that employs neural networks with many layers to analyze complex data. As AI continues to evolve, it is being integrated into numerous fields, including healthcare, finance, transportation, and entertainment, transforming how we interact with technology and improve efficiency across various domains.
