Final answer:
Cassandra is well-suited for IoT applications because of its ability to handle large volumes of data, thanks to its distributed architecture and robust data storage capabilities.
Step-by-step explanation:
Cassandra's suitability for IoT applications is primarily related to Its ability to handle large volumes of data. This characteristic makes Cassandra a popular choice for managing the high velocity, variety, and volume of data generated by IoT devices. With its distributed architecture, Cassandra provides robust data storage and fast data retrieval capabilities, crucial for real-time processing in IoT systems. It is designed to handle large amounts of experimental results and support the computation needs typically associated with big data and IoT use cases. Therefore, option b, which highlights a computer that can store and perform calculations on large data sets, aligns with Cassandra's core strength and utility in IoT applications.
