AI Vs Machine Learning Vs Deep Learning Vs Generative AI
Artificial Intelligence (AI)
It is the overarching field focused on creating machines or systems that can perform tasks typically requiring human intelligence, such as reasoning, learning, problem-solving, and language understanding. AI consists of various subfields, including ML, NLP, Robotics, and Computer Vision
Machine Learning (ML)
It is a subset of AI that focuses on developing algorithms that enable computers to learn from and make decisions based on data.
Instead of being explicitly programmed for every task, ML systems improve their performance as they are exposed to more data. Common applications include spam detection, recommendation systems, and predictive analytics.
Deep Learning
It is a specialized subset of ML that utilizes artificial neural networks with multiple layers to model complex patterns in data.
Neural networks are computational models inspired by the human brain’s network of neurons. Deep neural networks can automatically discover representations needed for future detection. Use cases include image and speech recognition, NLP, and autonomous vehicles.
Generative AI
It refers to AI systems capable of generating new content, such as text, images, music, or code, that resembles the data they were trained on. They rely on the Transformer Architecture.
Notable generative AI models include GPT for text generation and DALL-E for image creation.

How SQL Query Executes In A Database?
STEP 1
The query string first reaches the Transport Subsystem of the database. This subsystem manages the connection with the client. Also, it performs authentication and authorization checks, and if everything looks fine, it lets the query go to the next step.
STEP 2
The query now reaches the Query Processor subsystem, which has two parts: Query Parser and Query Optimizer.
The Query Parser breaks down the query into sub-parts (such as SELECT, FROM, WHERE). It checks for any syntax errors and creates a parse tree.
Then, the Query Optimizer goes through the parse tree, checks for semantic errors (for example, if the “users” table exists or not), and finds out the most efficient way to execute the query.
The output of this step is the execution plan.
STEP 3
The execution plan goes to the Execution Engine. This plan is made up of all the steps needed to execute the query.
The Execution Engine takes this plan and coordinates the execution of each step by calling the Storage Engine. It also collects the results from each step and returns a combined or unified response to the upper layer.
STEP 4
The Execution Engine sends low-level read and write requests to the Storage Engine based on the execution plan.
This is handled by the various components of the Storage Engine, such as the transaction manager (for transaction management), lock manager (acquires necessary locks), buffer manager (checks if data pages are in memory), and recovery manager (for rollback or recovery).

Top 20 AI Agent Concepts You Should Know
Agent: An autonomous entity that perceives, reasons, and acts in an environment to achieve goals.
Environment: The surrounding context or sandbox in which the agent operates and interacts.
Perception: The process of interpreting sensory or environmental data to build situational awareness.
State: The agent’s current internal condition or representation of the world.
Memory: Storage of recent or historical information for continuity and learning.
Large Language Models: Foundation models powering language understanding and generation.
Reflex Agent: A simple type of agent that makes decisions based on predefined “condition-action” rules.
Knowledge Base: Structured or unstructured data repository used by agents to inform decisions.
CoT (Chain of Thought): A reasoning method where agents articulate intermediate steps for complex tasks.
ReACT: A framework that combines step-by-step reasoning with direct environmental actions.
Tools: APIs or external systems that agents use to augment their capabilities.
Action: Any task or behavior executed by the agent as a result of its reasoning.
Planning: Devising a sequence of actions to reach a specific goal.
Orchestration: Coordinating multiple steps, tools, or agents to fulfill a task pipeline.
Handoffs: The transfer of responsibilities or tasks between different agents.
Multi-Agent System: A framework where multiple agents operate and collaborate in the same environment.
Swarm: Emergent intelligent behavior from many agents following local rules without central control.
Agent Debate: A mechanism where agents argue opposing views to refine or improve outcomes.
Evaluation: Measuring the effectiveness or success of an agent’s actions and outcomes.
Learning Loop: The cycle where agents improve performance by continuously learning from feedback or outcomes.
Over to you: Which other AI agent concept will you add to the list?
How RabbitMQ Works?
RabbitMQ is a message broker that enables applications to communicate by sending and receiving messages through queues. It helps decouple services, improve scalability, and handle asynchronous processing efficiently.
Here’s how it works:
A producer (usually an application or service) sends messages to the RabbitMQ broker, which manages message routing and delivery.
Within the broker, messages are sent to an exchange, which determines how they should be routed based on the type of exchange: Direct, Topic, or Fanout.
Bindings connect exchanges to queues using a binding key, which defines the rules for routing messages (for example, exact match or pattern-based)
Direct exchanges route messages to queues that match the routing key exactly, as shown with Queue 1.
Topic exchanges use patterns to route messages to matching queues.
Fanout exchanges broadcast messages to all bound queues, regardless of routing keys.
Finally, messages are pulled from the queues by a consumer, which processes them and can pass the results to other systems.
