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.
