  • Increases productivity and accuracy.
  • Can operate in hazardous conditions (e.g., deep-sea, space exploration).
  • Reduces human workload for repetitive tasks.
  • Capable of processing vast amounts of data quickly.

Disadvantages:

  • Expensive to develop and maintain.
  • Potential to replace human jobs in certain fields.
  • Relies on data; lacks human intuition and creativity.
  • Raises privacy issues due to data collection.

7.2 Concept of Cloud Computing

Notes:
Cloud Computing allows users to access and store data, applications, and services over the internet, instead of using a local hard drive or physical storage. This is often called “the cloud.” It offers various services, such as data storage, software access, and processing power, without needing high-end hardware.

Applications:

  • Data Storage: Google Drive, Dropbox.
  • Software as a Service (SaaS): Google Workspace, Microsoft Office 365.
  • Streaming Services: Netflix, YouTube.
  • Backup and Recovery: Secure backup for files and data.

Advantages:

  • Accessible from any device with internet.

Disadvantages:

  • Complex and requires advanced tools for analysis.
  • Raises privacy concerns if data is misused.
  • Storing and processing large datasets is costly.
  • Results can be inaccurate if data quality is low.

7.4 Concept of Virtual Reality (VR)

Notes:
Virtual Reality (VR) is a technology that creates a simulated environment through headsets, allowing users to interact in a 3D space. It’s commonly used for gaming, training simulations, and virtual tours.

Applications:

  • Gaming: Immersive experiences for players.
  • Medical Training: Simulations for practicing surgeries.
  • Virtual Tours: Real estate and tourism use VR for showcasing places.
  • Education: Allows students to explore different environments, like historical sites or science labs.

Advantages:

  • Engaging and immersive experiences.
  • Safe environments for training, especially in medical and military fields.
  • Eliminates travel by providing virtual access to distant locations.
  • Enhances learning by making it interactive.

Disadvantages:

  • High cost of VR devices and systems.
  • Requires strong hardware and internet.
  • Some users may experience motion sickness.
  • Limited VR content compared to traditional media.

7.5 Concept of E-Commerce, E-Medicine, and E-Government

Notes:
These digital services use technology to make life more convenient:

  • E-Commerce is online shopping.
  • E-Medicine offers online healthcare services, like consultations and appointments.
  • E-Government provides government services online, improving accessibility.

Applications:

  • E-Commerce: Amazon, eBay for shopping.
  • E-Medicine: Telemedicine apps for online doctor consultations.
  • E-Government: Filing taxes or applying for documents online.

Advantages:

  • Convenient and accessible anywhere with internet.
  • Reduces the need for physical travel.
  • Increases accessibility for remote areas.
  • Paperless and improves service efficiency.

Disadvantages:

  • Risks of data breaches and security threats.
  • Limited access for those without digital skills or internet.
  • Job displacement in traditional retail and government offices.
  • Service disruption if technology fails.

7.6 Concept of Mobile Computing

Notes:
Mobile Computing involves using portable devices (smartphones, tablets) that allow people to access information and perform tasks on the go. Mobile devices rely on wireless technology for connectivity.

Applications:

  • Social Media: Facebook, Twitter for communication.
  • Navigation and GPS: Google Maps for travel guidance.
  • Mobile Banking: Apps for financial transactions.
  • Gaming and Entertainment: Games, videos, and music streaming.

Advantages:

  • Highly portable; accessible anywhere, anytime.
  • Saves time with easy access to information.
  • Real-time communication and collaboration.
  • Supports entertainment, work, and learning activities.

Disadvantages:

  • Battery life limits usability.
  • Privacy risks with location and data tracking.
  • Distractions, especially when driving.
  • Limited power and speed compared to desktops.

7.7 Concept of Internet of Things (IoT)

Notes:
The Internet of Things (IoT) is a network of interconnected devices that collect and share data through the internet. IoT enables smart applications in homes, industries, and cities by automating tasks and improving efficiency.

Applications:

  • Smart Homes: Devices like smart thermostats and lights.
