- Java
- Python
- Ruby
C++ is often considered the most suitable language for real-time IoT applications due to its efficiency and low-level control over hardware. It allows for precise resource management, which is crucial for real-time systems. While Python, Java, and Ruby have their merits, they may not be as well-suited for real-time IoT.
The process of ensuring that an IoT device operates within its intended purpose and network is called:
- Device lifecycle management
- Device reconfiguration
- Device synchronization
- IoT device programming
The process of ensuring that an IoT device operates within its intended purpose and network is called "Device lifecycle management." It involves activities like provisioning, configuration, monitoring, and maintenance to keep the device functioning as expected.
The term "Internet of Things" was first coined by:
- Kevin Ashton
- Linus Torvalds
- Mark Zuckerberg
- Tim Berners-Lee
The term "Internet of Things" (IoT) was first coined by Kevin Ashton, a British technology pioneer, in the late 1990s. Ashton used this term to describe a network of objects or "things" connected to the internet, which could communicate and share data without human intervention. This concept laid the foundation for the IoT we know today.
The vision of a global network of interconnected computer networks, which would later give rise to IoT, was first proposed by ________.
- Alan Turing
- Bill Gates
- J.C.R. Licklider
- Nikola Tesla
The vision of a global network of interconnected computer networks, which laid the foundation for the Internet of Things (IoT), was first proposed by "J.C.R. Licklider." His ideas and contributions to the development of the ARPANET, a precursor to the internet, were instrumental in shaping the concept of IoT.
As IoT devices proliferate, the need for ________ in data storage becomes critical to ensure data integrity and quick retrieval.
- Compression
- Latency
- Scalability
- Security
As the number of IoT devices grows, ensuring data integrity and quick retrieval is crucial. Security measures become critical to protect the data from various threats and vulnerabilities.
Advanced visualization tools in IoT are crucial for:
- Reducing data storage costs.
- Enhancing the aesthetics of IoT dashboards.
- Gaining insights from complex data.
- Managing IoT device firmware.
Advanced visualization tools in IoT are crucial for gaining insights from complex data. With the enormous volume of data generated by IoT devices, visualizations help in presenting the data in a comprehensible manner. This is vital for analyzing trends, anomalies, and making informed decisions in IoT applications.
How can blockchain technology enhance the security of IoT devices?
- Data immutability
- Decentralized control
- Improved battery life
- Real-time data analysis
Blockchain enhances IoT security through data immutability. Blockchain's distributed ledger ensures that once data is recorded, it cannot be altered, making it ideal for securing the integrity of IoT data, such as sensor readings and device logs.
Devices connected via ________ are known for their ability to connect directly without requiring a central hub or router.
- Bluetooth
- Thread
- Wi-Fi
- Zigbee
Devices connected via the Thread wireless protocol are known for their ability to create self-healing mesh networks and connect directly with one another. Thread allows devices to communicate in a decentralized manner, eliminating the need for a central hub or router.
After a series of unauthorized data breaches from its IoT devices, a company decided to implement a system where each device had to present a unique digital certificate to communicate. This approach emphasizes:
- Data Encryption
- Data Storage
- Firewall Protection
- Identity and Authentication
Requiring unique digital certificates for each device emphasizes Identity and Authentication. It ensures that each device is who it claims to be, adding a layer of security to prevent unauthorized access or data breaches.
