Computers are electronic devices that process data and perform tasks based on instructions known as programs. They have become essential tools in almost every field, including education, healthcare, communication, and entertainment, due to their speed, accuracy, and ability to handle large amounts of information.

Artificial Intelligence (AI) is a branch of computer science that focuses on creating machines or software that can think, learn, and solve problems like humans. AI enables computers to perform tasks such as speech recognition, decision-making, and visual perception. It is widely used in technologies like virtual assistants, self-driving cars, and medcal diagnostics, making our lives easier and more efficient.
