In cybersecurity and artificial intelligence, 'context' refers to the background information, environment, or circumstances surrounding a particular event, interaction, or data. For AI systems, context helps interpret user queries, understand intent, and provide relevant responses. In cybersecurity, context can include user behavior, system status, and historical data, which together help determine if an activity is normal or potentially malicious. Proper understanding of context allows systems to make more accurate decisions, improving security and user experience.
