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.
