Study Notes
SaaS Applications
- SaaS applications are also known as web-based, on-demand, or hosted software.
- SaaS providers manage security, availability, and performance for these applications.
- Examples include Google Docs, Gmail, and Office applications.
Big Data Analytics
- Big data analytics involves studying massive datasets.
- Big data is characterized by its massive volume, velocity, and variety, making it challenging to manage with traditional databases.
- Sources of big data include social networks, videos, images, sensors, and sales records.
- Steps in big data analysis include data cleaning, munging, processing, and visualization.
- Examples of big data applications include bank transactions, IoT data for vehicle tracking, e-commerce (like Big Basket), and health/fitness data from wearables.
Communications Protocols
- Communication protocols are essential for IoT systems, enabling network connectivity and application linking.
- Protocols allow devices to exchange data over networks.
- Multiple protocols can address different aspects of communication.
- A group of working protocols is a protocol suite or stack.
- Applications of protocols include data encoding and addressing schemes.
Embedded Systems
- Embedded systems are combinations of hardware and software designed for specific tasks.
- Components include microcontrollers, microprocessors, memory, networking units (e.g., Ethernet, Wi-Fi), input/output units (e.g., displays), and storage (e.g., flash memory).
- Embedded systems collect data and transmit it to the internet.
- Examples include digital cameras, DVD players, industrial robots, and wireless routers.
