IP addresses and ports are features of which Cyberspace Layer?

The correct choice is the Logical Layer because IP addresses and ports are both fundamental components that enable the addressing and communication protocols necessary for data exchange across networks.

Within the context of the Logical Layer, IP addresses serve to identify specific devices or endpoints on a network, allowing data packets to be routed correctly from one device to another. Ports complement this system by delineating specific services or applications running on those devices, facilitating targeted communication. Together, they form a crucial part of the network's logical addressing scheme, enabling the layered architecture where data can move up and down the model to find the most efficient path to its destination.

This layer emphasizes the logical organization of data and how devices interact on a network level, rather than the physical aspects like cables and hardware setup found in the Physical Network Layer or other layers that focus on user interaction or transmission specifics. It is within this structured networking framework that the capabilities of IP addresses and ports are utilized for effective communication.
