Study Notes
Machine to Machine Communication (M2M)
- M2M allows direct data exchange between devices without human interaction, enhancing automation in industrial settings.
- Applications include communication from sensors or meters, such as temperature and inventory levels, to software systems for decision-making processes.
- Connectivity options encompass serial connections, powerline communications, and a growing trend towards wireless protocols in the industrial IoT.
- M2M networks facilitate end-to-end connectivity through a combination of radio, gateways, core networks, and backend servers.
Differences Between M2M and IoT
- M2M focuses on direct communication between machines, while IoT encompasses broader connectivity, integrating devices into the internet for enhanced interaction.
- M2M is designed for point-to-point connections; IoT utilizes cloud-based architectures for scalability.
- Devices in M2M can operate independently of the internet, unlike IoT, which relies on internet connectivity.
- M2M supports limited device connections simultaneously, whereas IoT allows for greater scalability and concurrent user access.
- M2M typically lacks support for open APIs, while IoT often includes such functionalities, promoting integration and innovation.
Terminology in IoT
- Microprocessor: a compact integrated circuit designed to process information.
- Microcontroller: a small computer on a single integrated circuit containing a processor, memory, and programmable input/output peripherals.
- Embedded System: a computer designed to perform dedicated functions within a larger system.
- API (Application Programming Interface): a set of protocols for building and interacting with software applications.
- Latency: the delay before a transfer of data begins following an instruction.
- Telemetry: automated data collection from remote sources.
- SoC (System on Chip): integrates all the components of a computer or electronic system onto a single chip.
Internet of Things (IoT)
- IoT involves connecting everyday objects and sensors to the internet, allowing them to generate, exchange, and process data with minimal human input.
- Facilitates remote monitoring and control through integration with communication technologies.
- Enables a vast network of interconnected devices, enhancing automation across various sectors.
Cybersecurity in M2M and IoT
- Password attacks exploit vulnerabilities in user authentication systems, with brute-force methods and dictionary attacks being common tactics.
- Types of malware attacks include macro viruses, file infectors, system infectors, Trojans, and ransomware, each employing distinct strategies for infiltration.
System Errors and Debugging
- Possible reasons for system failure include overheating, dust accumulation, faulty fans, power connection issues, and uninstalled drivers.
- Debugging involves identifying and resolving these potential hardware and software malfunctions.
Smart Living Environments
- Smart technologies in homes include automation for lighting, doors, and multimedia systems, reacting to human presence or environmental changes.
- Devices like smart fridges, chairs, clocks, mirrors, and furniture adapt to user needs, enhancing convenience and efficiency.
- Advanced features allow these systems to communicate, improving user interaction and overall functionality.
