Artificial Intelligence (AI) is the field of computer science and technology focused on creating smart machines and systems that can mimic human-like thinking. This covers a wide range of functions like learning, problem-solving, and decision-making. AI works closely with machine learning, especially in cybersecurity. By using algorithms, data analysis, and recognizing patterns, AI systems with machine learning can replicate human intelligence and gain insights from data trends. This helps them improve over time, becoming better at processing information, adapting to new situations, and handling tasks that used to need human thinking. This combination strengthens cybersecurity by bridging the gap between machine abilities and human intelligence.
