Artificial Intelligence (AI)
Artificial Intelligence, commonly known as AI, refers to the capability of machines—especially computer systems—to perform tasks that typically require human intelligence. Broadly, it involves creating systems or software that can understand their surroundings, analyze data, learn from experience, and make decisions or take actions to accomplish specific objectives intelligently and efficiently.

AI is a specialized branch of computer science dedicated to developing algorithms and models that allow machines to carry out tasks traditionally requiring human intelligence. This involves abilities such as reasoning, learning from experience or data, and adjusting effectively to new or changing situations.
Applications of Artificial Intelligence (AI)
AI has become deeply integrated into modern technology, powering numerous tools and services we use daily. Some of its most notable applications include:
Web Search Engines: Platforms like Google Search rely on AI algorithms to analyze queries and deliver the most relevant results.
Recommendation Systems: Services such as YouTube, Amazon, and Netflix use AI to study user preferences and suggest personalized content or products.
Virtual Assistants: AI-driven assistants like Siri, Google Assistant, and Alexa interact with users, process natural language, and perform various tasks.
Autonomous Vehicles: Companies such as Waymo use AI to enable self-driving cars to navigate, detect obstacles, and make real-time driving decisions.
Generative and Creative Tools: Applications like ChatGPT and AI-based art or music generators create text, visuals, or audio compositions from user prompts.
Game Analysis and Play: AI systems have achieved superhuman performance in strategy games such as chess and Go by evaluating millions of potential moves.
Interestingly, many of these technologies have become so common that they are no longer explicitly recognized as AI. Tools like search engines, recommendation systems, and voice assistants are now viewed as standard technologies, even though they operate on complex AI frameworks. As AI continues to evolve, its presence becomes more seamless and integrated into the everyday digital experience.
Types of Artificial Intelligence (AI)
AI can be classified in different ways depending on its capabilities and functionality.
1. Based on Capabilities
a. Narrow AI (Weak AI):
This form of AI is built to perform a specific task or a set of limited tasks. It operates under predefined conditions and cannot think beyond its programming.
Examples:
Virtual assistants like Siri or Google Assistant
Recommendation algorithms on Netflix and Amazon
Email spam filters
b. General AI (Strong AI):
General AI represents machines that could understand, learn, and apply intelligence across various tasks—just like a human. Such AI does not yet exist but remains a major goal in artificial intelligence research.
c. Superintelligent AI:
This is a hypothetical form of AI that would surpass human intelligence in every domain, from creativity to decision-making. It could potentially outperform humans in all intellectual pursuits, though it remains a futuristic concept.
2. Based on Functionality
a. Reactive Machines:
These AI systems can respond to specific inputs but lack memory or learning ability. They act purely on present data without recalling past experiences.
Example: IBM’s Deep Blue, the chess-playing computer that defeated Garry Kasparov, is a classic example.
b. Limited Memory:
AI systems in this category can use past data to make better future decisions. Most modern AI applications, such as self-driving cars, fall under this type—they learn from previous experiences to improve performance.
c. Theory of Mind:
Still in the experimental stage, this AI would be capable of understanding human emotions, intentions, and social behavior. It could enable machines to interact more naturally with people.
d. Self-Aware AI:
This theoretical form of AI would possess its own consciousness, emotions, and self-awareness. While often explored in science fiction, such technology does not yet exist.
