in simple and easy language, with definitions, diagrams, examples, and key exam points.
Data streaming is the continuous flow of data generated, processed, and analyzed in real-time (instantly as it is created).
👉 Simple meaning: Data is processed immediately while it is being generated
Data Source → Continuous Data Flow → Stream Processing System → Real-Time Output
Data is processed immediately
Live sports scores
Small delay in processing
Social media notifications
Combines streaming and batch processing
Business analytics systems
Data Source → Message Broker → Stream Processor → Storage/Output
✔ Real-time analysis ✔ Faster decision making ⭐ ✔ Efficient processing ✔ Low latency ✔ Useful for live applications
❌ High processing power needed ❌ Complex system design ❌ Data consistency issues ❌ Network dependency ❌ Security risks
Mobile Cloud Computing (MCC) is a technology that combines mobile devices and cloud computing, where data and applications are stored and processed in the cloud instead of the mobile device.
👉 Simple meaning: Using cloud power on mobile phones to run apps and store data
Mobile Device → Internet → Cloud Server → Processing → Result Returned
