    Study Notes

    Web Browsers and URLs

    • Browsers facilitate navigation across the web, allowing users to move between websites easily.
    • Major browsers include Google Chrome, Mozilla Firefox, Microsoft Internet Explorer, and Apple Safari.
    • A Uniform Resource Locator (URL) is the specific address for a webpage, comprised of two main components:
      • Protocol: Indicates how to access a resource; HTTP is the most common for web traffic.
      • Domain Name: Identifies the specific location of resources; the top-level domain (TLD) follows the final dot in the URL.

    HTML and Web Pages

    • Hypertext Markup Language (HTML) is the foundational markup language for creating web pages.
    • Web pages contain information and links (hyperlinks) to related documents, potentially including text, graphics, audio, and video clips.

    Cloud Computing

    • Defined as delivering computing services (CPU, RAM, storage, etc.) over the internet rather than on-premise hardware.
    • Examples of cloud service providers include Amazon Web Services (AWS), Microsoft Azure, and Google Cloud.
    • The analogy of cloud computing likens it to a bus carrying diverse passengers, where data is shared among different users efficiently.
    • The term "cloud" originates from network design visuals used by engineers that appear cloud-like.
    • Benefits include:
      • Cost reduction for IT infrastructure.
      • Enhanced performance and reduced maintenance.
      • Instant software updates and improved compatibility.
      • Effective backup, recovery, scalability, and increased data safety.

    Types of Clouds

    • Private Cloud: Dedicated to a single organization, useful for internal interactions.
    • Community Cloud: Shared resources for a specific community or group of organizations.
    • Public Cloud: Resources available to the public, commonly used for business-to-consumer interactions.
    • Hybrid Cloud: Combines multiple cloud environments to serve both B2B and B2C interactions.

    Internet vs. Web

    • Internet: The physical infrastructure (wires, satellites) that connects numerous computers globally.
    • Web: A multimedia interface providing access to resources on the internet, allowing communication, shopping, education, and entertainment.

    Accessing the Internet

    • Internet Service Providers (ISPs) facilitate internet access, utilizing telephone lines, cable, or wireless connections.
    • Major ISPs include PLDT, Globe, and Bayantel.

    Internet of Things (IoT)

    • Refers to a network of physical devices embedded with software and sensors, enabling data collection and exchange.
    • Aims to create “smart” environments by connecting everyday devices to the internet.
    • Core components include:
      • Sensors/Devices: Collect environmental data.
      • Connectivity: Transmission of data to cloud infrastructure via mobile or Wi-Fi networks.
      • Data Processing: Analyzes collected data for insights.
      • User Interface: Presents information to users, sometimes through notifications or alarms.

    Challenges and Benefits of IoT

    • Challenges:
      • Insufficient updates and testing.
      • Data security and privacy concerns.
      • Software complexities and high volumes of data to interpret.
    • Benefits:
      • Enhanced technical optimization and improved data collection.
      • Reduced waste through real-time data-driven decision-making.
      • Improved customer engagement by promptly addressing issues.

    Disadvantages of IoT

    • Security vulnerabilities due to interconnected devices with potentially inadequate authentication.
    • Privacy risks from extensive personal data exposure without user consent.
    • Complexity in system design, making integration with diverse systems challenging.
