Which set of components constitutes Physical Layers?

Which set of components constitutes Physical Layers?

• A. Runtime & OS, Infrastructure, Network and Storage
• B. Applications
• C. User Manuals
• D. Cloud Services

Answer: (A)

The Physical Layer covers the hardware-backed environment and the foundational software that everything else runs on. It includes the runtime and operating system, the underlying infrastructure, and the network and storage that supply compute, memory, connectivity, and data storage. Applications sit on top of this layer, not in it, so they aren’t part of the physical layer. User manuals are just documentation, and cloud services are external services that abstract or sit above the physical hardware. So, the combination that includes Runtime & OS, Infrastructure, Network and Storage best represents the Physical Layer.
