IoT gateway must provide

Solution(By Examveda Team)

An IoT gateway serves as an intermediary between IoT devices and a central system or Cloud. One of the key functions that an IoT gateway must provide is protocol abstraction. This means that the gateway should be capable of translating and adapting different communication protocols used by various IoT devices into a common format that can be understood by the central system.

The role of protocol abstraction is to ensure seamless communication between devices with different communication protocols. By abstracting these protocols, the gateway simplifies the integration of diverse devices into the IoT ecosystem, allowing for efficient data exchange and management.

Options A (simple and fast installation), B (security with hardware), and C (data storage) are important considerations for IoT gateways as well, but protocol abstraction specifically addresses the challenge of managing communication diversity in IoT networks.

Hence, the correct answer is Option D: protocol abstraction. An IoT gateway must provide protocol abstraction to enable effective communication between devices with varying communication protocols.
