Artificial Intelligence (AI)is a branch of computer science focused on creating systems that can perform tasks that typically require human intelligence, such as understanding language, recognizing patterns, solving problems, and making decisions. Modern AI encompasses techniques like machine learning, where algorithms learn from data to improve their performance over time, and deep learning, which mimics the structure of the human brain through neural networks. AI is transforming industries from healthcare and finance to art and education, raising new possibilities and ethical questions about automation, creativity, and the future of human work.
