Which of the following is NOT classified as an End-User Device?

The classification of end-user devices typically includes those items that directly interact with users and facilitate access to information systems and applications. End-user devices are intended for tasks such as browsing, computing, or communication. Laptops, tablets, and wearables are all designed for use by individuals, enabling them to perform work-related tasks, manage personal information, or use applications directly.

A router, on the other hand, functions primarily as a networking device that connects multiple devices within a network, enabling communication between them or providing access to the internet. Its role is not to interface directly with users but rather to facilitate the transmission of data between end-user devices. Therefore, it does not fall under the category of end-user devices, making it the correct answer.

This distinction is important when considering network architecture and device management within information systems, as understanding which devices serve a user-facing function versus a technical role helps in designing effective controls and security measures.
