AI stands for “Artificial Intelligence”. This is a field in computer science that focuses on developing computer systems capable of performing tasks that normally require human intelligence.

“What is AI?” You have probably asked yourself this question at least once when unlocking your phone with your face, ordering your virtual assistant to make a call, or being surprised when YouTube recommends videos that are right for you. In the digital age, artificial intelligence has penetrated almost every aspect of life from entertainment, healthcare to education and business.
From personalized movie recommendations on Netflix, Google’s instant language translation, to fast and accurate medical diagnostics – AI is quietly changing the way we work and live every day. But what exactly is AI? How do these machines “learn” and “think” like humans? And what makes artificial intelligence the core technology of the digital age?
In this article, I will take you from the basic concepts of AI, how to classify, operating principles, practical applications, to the challenges and upcoming development directions. Let's start the journey to learn about the technology that is contributing to reshaping the world around us!
1. AI Definition and Bilingual Terminology Explanation
1.1. What is AI?
AI stands for “Artificial Intelligence”. This is a field in computer science that focuses on developing computer systems capable of performing tasks that normally require human intelligence.
To understand better, let's analyze each component of this term:
Artificial (Artificial): Made by humans, not naturally
Intelligence: The ability to learn, reason, solve problems and make decisions
1.2. Origin and Development History
The term “Artificial Intelligence” was first coined by John McCarthy in 1956 at the Dartmouth Conference. However, the idea of intelligent machines has been around for a long time in literature and philosophy.
The AI development process goes through many stages:
1950s-1960s: The beginning period with the first programs
1970s-1980s: The “AI winter” period due to computational limitations
1990s-2000s: Boom with increased computer power
2010s-present: The era of deep learning and widespread artificial intelligence
1.3 Basic characteristics that make AI different
AI differs from traditional technologies in the following ways:
Ability to learn: Unlike conventional software that simply follows pre-programmed commands, AI can learn from data and improve performance over time.
Decision automation: AI can analyze information, recognize patterns, and make decisions without direct human intervention.
Adapting to new environments: AI systems are able to handle unprecedented situations by applying learned knowledge.
2. AI Classification
2.1. Narrow AI
Weak AI, also known as narrow AI, is a type of artificial intelligence designed to perform a specific task or a group of related tasks. This is the type of AI we use every day.
Typical examples of weak AI:
- Netflix, YouTube recommendation systems
- Virtual assistants like Siri, Google Assistant
- Facebook facial recognition algorithm
- Google Translate translation system
- Self-driving cars (within a certain range)
Main features:
- Highly specialized in a specific field
- Inability to transfer knowledge to another task
- Very high performance within the designed range
- Safe and controllable
2.2. Strong AI (General AI)
Strong AI or general AI is a form of artificial intelligence that has the ability to understand, learn, and apply human-like intelligence in all fields. Currently, strong AI is still just a theory and a long-term goal of researchers.
Future outlook:
- The ability to reason abstractly like humans
- Can transfer knowledge between different fields
- Learn and develop yourself without intervention
- Can replace humans in most intellectual work
2.3. Distinguish from related concepts
Machine Learning
Machine learning is a sub-branch of AI that focuses on developing algorithms that allow computers to learn from data without being specifically programmed for each task.
Deep Learning
Deep learning is a sub-branch of machine learning that uses multi-layered artificial neural networks to simulate the way the human brain processes information. To better understand convolutional neural networks and their applications.
3. Operating Principle and Basic Technology of AI
3.1. Machine “learning” and information processing process
To understand how AI works, imagine a child learning to recognize a cat. The child is shown hundreds of different pictures of cats, and the brain automatically recognizes common features: four legs, whiskers, pointy ears, long tail. AI works similarly, but with speed and massive amounts of data.
Basic steps in the AI process:
Data collection: Feed the computer a large amount of sample data
Preprocessing: Clean and normalize data so that it can be understood by computers.
Model training: The computer analyzes data to find patterns and rules
Testing and Tuning: Assessing accuracy and improving the model
Application Deployment: Putting the Model into Practical Use
Continuous Updates: Learn from new data to improve performance
3.2. Basic models and algorithms
Natural Language Processing (NLP)
- This is the field that helps computers understand and process human language. NLP is applied in:
- Automatic translation (Google Translate)
- Social Media Sentiment Analysis
- Chatbot automatically responds to customers.
- Automatic text summarization
Image recognition
- Using algorithms to analyze and understand the content in images:

- Medical diagnosis from X-ray, MRI
- Product quality control in factory
- Self-driving cars recognize signs and obstacles.
Machine Learning and Deep Learning
Supervised Learning: Supervised Learning with Pre-Labeled Data
Unsupervised Learning: Learn without supervision, find patterns in data
Reinforcement Learning: Learning through rewards and punishments
3.3. The role of Big Data
Data is the “fuel” of AI. Without quality data, AI cannot function effectively. Big Data provides:
Volume: Millions, billions of data points for AI to learn from
Variety: Text, images, audio, video from various sources
Velocity: Data is updated continuously in real time
Veracity: Clean, reliable data to ensure accurate results
