Study Notes
Data Analytics Overview
- A systematic method for converting raw data into actionable insights.
- Involves tools and technologies for data collection, cleaning, transformation, and modeling.
- Plays a crucial role in enhancing decision-making processes within organizations.
- Essential for business growth and optimizing operational performance.
IoT Analytics
- Focuses on gathering, processing, and analyzing data from IoT devices.
- Generates large volumes of data that yield valuable insights as more devices connect to the Internet.
- Represents a subset of Big Data with heterogeneous streams that must be transformed for utility.
Roles of Data Analysts in IoT
- Establishing organizational goals to guide data analysis efforts.
- Employing data mining techniques to extract useful information.
- Conducting data cleaning to ensure data accuracy and quality.
- Analyzing data to derive meaningful conclusions.
- Identifying trends and recognizing patterns for further insights.
- Reporting findings to stakeholders for informed decision-making.
- Maintaining data and systems to safeguard integrity and accessibility.
Importance of IoT Data Analytics
- Provides actionable insights for better operational efficiency.
- Enables real-time decision-making based on live data streams.
- Facilitates predictive maintenance to reduce downtime and costs.
- Analyzes cost-effectiveness for improved budgeting.
- Enhances customer experience through tailored services.
- Strengthens security and anomaly detection capabilities.
- Offers scalability and flexibility to adapt to changing needs.
- Ensures compliance with regulations and standards.
- Drives innovation and development of new products.
IoT Analytics Use Case
- Walmart utilizes IoT analytics to monitor customer arrival rates and checkout times for effective queue management across its stores.
Physical Network Topology
- Describes the physical layout of devices in a network, essential for understanding connectivity and communication flow.
Star Topology
- Each device connects directly to a central hub.
- Advantages: Cost-effective, easy installation, and minimal cabling.
- Disadvantage: Single point of failure.
Bus Topology
- One backbone cable connects all devices; involves drop lines and taps.
- Signal degrades with distance and tapping, limiting the number of connections.
Ring Topology
- Devices are interconnected in a circular manner; each device acts as a repeater.
- Advantages: Easy fault isolation and constant signal circulation.
- Disadvantage: Unidirectional traffic can disrupt the entire network.
Network Categories
- Defined by size, ownership, coverage distance, and physical architecture.
Local Area Network (LAN)
- Connects devices within a limited area, like a building or campus.
- Allows resource sharing and employs a single transmission medium.
- Protocols used can be unicast (specific) or broadcast (general).
Metropolitan Area Network (MAN)
- Spans an entire city, owned and operated by private companies.
Wide Area Network (WAN)
- Facilitates long-distance transmissions across large geographic areas, potentially worldwide.
- An enterprise network is often a privately owned WAN.
Internet vs. Intranet
- Internet: A vast interconnected system of networks using TCP/IP protocols, encompassing various types of networks.
- Intranet: A private, internal network restricted to an organization’s staff, facilitating internal communication and resource access.
Protocols and Standards
- Govern the rules of data communication, defining what, how, and when data is transmitted.
- Comprised of syntax (data structure), semantics (meaning of bits), and timing (scheduling and data flow).
Class Activities
- Analyze the functions and operations of hubs, switches, routers, firewalls, and gateways.
- Examine the significance of device management in IoT applications and identify limitations of IoT in fitness contexts.
