Study Notes

Definition and Overview of M2M Communication

Machine-to-machine (M2M) communication involves automated data exchange between devices without human interaction.
Technologies include serial connections, powerline communication (PLC), and wireless connections, especially in the industrial Internet of Things (IoT).
Wireless communication enhances ease of use and connectivity for various applications.
M2M solutions enable data capture from devices like sensors and meters for applications ranging from industrial processes to inventory management.

Key Components of M2M Networks

M2M networks consist of radio systems, access networks, gateways, core networks, and backend servers.
Devices within an M2M setup can communicate in both "uplink" (sending data) and "downlink" (receiving commands) configurations.

Comparison Between M2M and IoT

M2M focuses on point-to-point machine communication, while IoT emphasizes connectivity through the internet.
IoT devices require internet access, whereas M2M devices may function independently of the internet.
M2M tends to be hardware-centric, whereas IoT integrates both hardware and software components.
Scalability differs, with M2M being less scalable compared to the more expansive IoT.

IoT Security Challenges

Data Encryption: Important for safeguarding information; utilize SSL and secure protocols for wireless transmission.
Data Authentication: Essential to prevent misuse of stored data, akin to using student ID cards for attendance.
Hardware Issues: Include costs, the need for hardware changes, and susceptibility to cyber-attacks.

Security Measures for Smart Homes

Use strong Wi-Fi encryption and create a unique router name for security.
Establish a guest network to isolate visitors.
Modify default usernames and passwords to enhance account security.
Regularly update software and review device settings for unauthorized changes.
Implement two-step authentication for better protection.

Common Cyber Threats

Password Attacks: Common approach to compromise accounts through brute-force or dictionary methods.
Malware includes various forms such as macro viruses, file infectors, Trojans, and ransomware, posing significant risks.

System Error Debugging

Common causes for system failures include overheating PCs, dust accumulation, malfunctioning CPU fans, faulty power connections, and uninstalled support drivers.
Effective debugging involves identifying these issues and rectifying them systematically.

Smart Living Environments

Smart environments utilize technology to enhance user experiences, adapt to human activities, and automate tasks.
Smart devices like automated door systems, lighting, and environmental controls enhance comfort and utility in homes and buildings.
Examples include smart fridges for stock management and innovative furniture designed for user interaction and adaptability.
