Summary -Chapter 3 : Emerging Trends

Artificial Intelligence (AI):

• AI aims to simulate human-like intelligence in machines.
• Subfields include machine learning and natural language processing (NLP).
• Applications range from digital personal assistants to machine translation and immersive experiences.

Big Data:

• Big Data refers to vast, complex datasets that cannot be processed with traditional methods.
• Characterized by volume, velocity, variety, veracity, and value.
• Data analytics technologies are used to extract insights from Big Data for various purposes.

Internet of Things (IoT):

• IoT is a network of interconnected devices embedded with sensors and software.
• Enables devices to communicate and interact with each other, facilitating automation and remote control.
• Applications include smart homes, smart cities, and various industries.

Cloud Computing:

• Cloud computing delivers computing services over the Internet, providing on-demand access to resources.
• Three service models: Infrastructure as a Service (IaaS), Platform as a Service (PaaS), and Software as a Service (SaaS).
• Offers scalability, cost-effectiveness, and accessibility from anywhere.

Grid Computing:

• Grid computing connects geographically dispersed and heterogeneous computational resources to solve large-scale tasks.
• Distinct from cloud computing, as it focuses on specific applications and creates a virtual supercomputer.
• Types include data grid and CPU grid, leveraging middleware like the Globus toolkit.

Blockchains:

• Blockchain technology enables decentralized and secure digital transactions through shared databases.
• Consists of blocks of data linked together in a chain, ensuring transparency and integrity.
• Applications span digital currency, business, governance, healthcare, and more.
