Internet of Things (IoT): A network of interconnected physical devices or objects that can collect and exchange data through the internet. Imagine your home appliances talking to each other and adjusting settings automatically based on your preferences.
Big Data: Extremely large sets of structured or unstructured data that require advanced tools for processing and analysis. It's like having a massive library filled with books stacked from floor to ceiling, requiring specialized techniques to organize and extract useful information.
Cybersecurity: Measures taken to protect computer systems, networks, and data from unauthorized access or damage. Think of it as installing high-security locks and alarm systems around valuable possessions in your house to prevent theft or vandalism.
