Smart computers are advanced machines that can perform tasks typically requiring human intelligence. They use technologies like artificial intelligence (AI) and machine learning to analyze data, recognize patterns, and make decisions. This allows them to assist in various fields, from healthcare to finance, improving efficiency and accuracy. These computers can learn from experience and adapt to new information, making them more effective over time. Examples include virtual assistants like Siri and Alexa, which understand voice commands, and self-driving cars, which navigate roads using sensors and algorithms. Smart computers are transforming how we interact with technology.
