Unit 7: Recent Trends in Technology (9 Hours)

7.1 Concept of Artificial Intelligence (AI) and Robotics

  • Artificial Intelligence (AI):

    • Refers to the simulation of human intelligence processes by machines, especially computer systems.
    • Key areas include machine learning, natural language processing, and computer vision.
    • Applications: Virtual assistants (like Siri, Alexa), recommendation systems, autonomous vehicles.

  • Robotics:

    • Involves the design, construction, operation, and use of robots.
    • Robotics combines AI to enhance robot functionalities, enabling them to perform tasks autonomously.
    • Applications: Manufacturing (industrial robots), healthcare (surgical robots), and exploration (Mars rovers).

7.2 Concept of Cloud Computing

  • Cloud Computing:
    • Delivery of computing services (servers, storage, databases, networking, software) over the internet (“the cloud”).
    • Models:
      • Infrastructure as a Service (IaaS): Virtualized computing resources over the internet.
      • Platform as a Service (PaaS): Provides a platform allowing customers to develop, run, and manage applications.
      • Software as a Service (SaaS): Delivers software applications over the internet on a subscription basis.
    • Benefits: Scalability, cost efficiency, and flexibility.

7.3 Concept of Big Data

  • Big Data:
    • Refers to extremely large data sets that may be analyzed computationally to reveal patterns, trends, and associations.
    • Characteristics known as the 3 Vs:
      • Volume: Amount of data generated.
      • Velocity: Speed at which data is generated and processed.
      • Variety: Different types of data (structured, unstructured, semi-structured).
    • Technologies: Hadoop, Spark, and NoSQL databases are commonly used to manage and analyze big data.
    • Applications: Social media analysis, healthcare diagnostics, and fraud detection.

7.4 Concept of Virtual Reality (VR)

  • Virtual Reality (VR):
    • A simulated experience that can be similar to or completely different from the real world.
    • VR technology uses computer-generated simulations to create immersive environments for users.
    • Applications: Gaming, training simulations (military, medical), and virtual tours (museums, real estate).

7.5 Concept of E-com, E-medicine, E-gov

  • E-commerce (E-com):

    • Refers to buying and selling goods or services using the internet.
    • Involves various business models, including B2B (business to business), B2C (business to consumer), and C2C (consumer to consumer).
    • Benefits: Convenience, wider reach, and lower operational costs.

  • E-medicine:

    • Involves the use of electronic communications and technology to provide health services and information.
    • Applications include telemedicine, electronic health records (EHRs), and remote monitoring.
    • Benefits: Improved access to healthcare, especially in remote areas.

  • E-governance (E-gov):

    • The use of digital tools and systems to provide government services to citizens.
    • Enhances transparency, efficiency, and accessibility in government operations.
    • Examples: Online tax filing, e-voting, and digital ID systems.

7.6 Concept of Mobile Computing

  • Mobile Computing:
    • Involves the use of portable computing devices (smartphones, tablets, laptops) that allow users to access and manage data on the go.
    • Key technologies: Wireless networks (Wi-Fi, cellular networks), mobile applications, and cloud services.
    • Applications: Navigation apps, mobile banking, and social networking.

7.7 Concept of Internet of Things (IoT)

  • Internet of Things (IoT):
    • Refers to the interconnection of everyday devices and objects to the internet, allowing them to send and receive data.
    • Examples: Smart home devices (thermostats, lights), wearable fitness trackers, and industrial IoT applications.
    • Benefits: Increased efficiency, automation, and real-time monitoring of systems.
