Cognitive Networks are advanced communication systems that use artificial intelligence to improve their performance. They can learn from the data they process, adapting to changing conditions and user needs. This allows them to optimize resource usage, enhance connectivity, and provide better services. These networks analyze information in real-time, making decisions based on patterns and trends. By incorporating concepts from machine learning and data analytics, Cognitive Networks can automatically adjust their operations, leading to more efficient and reliable communication. This technology is particularly useful in areas like 5G networks and Internet of Things (IoT) applications.
