Question

system integration of a digital device in the iot ecosystem occurs at many levels, including the network, software, and hardware. true false question 4 5 pts check all that are true about power sources. main electricity only is used for data center infrastructure. energy harvesting, such as solar and wind are only good for homes. main power, renewable sources that can be harvested and batteries all play a part in the digital iot world. security of power sources is a major concern in the iot ecosystem.

Explanation:

• For the first question: In IoT ecosystem, system integration of digital devices indeed occurs at network, software, and hardware levels.
• For the second question:
• Main electricity is not the only power source for data center infrastructure (e.g., backup generators can be used).
• Energy harvesting like solar and wind is used in various IoT - related applications beyond homes (e.g., in smart cities for streetlights).
• Main power, renewable harvested sources, and batteries are all part of the digital IoT world (e.g., some IoT sensors use batteries, while larger IoT gateways may use main power with renewable backup in some cases).
• Security of power sources (e.g., preventing power - supply tampering that could disrupt IoT device operation) is a major concern in the IoT ecosystem.

Answer:

• First question: True
• Second question: Main power, renewable sources that can be harvested and batteries all play a part in the digital IoT world; Security of power sources is a major concern in the IoT ecosystem.
