Network fundamentals: which option is NOT considered a basic configuration in data communication networks?

Introduction / Context:
Data communication networks connect intelligent devices to exchange data over links and switching equipment. Basic configurations describe patterns such as host-to-host, host-to-terminal via a front-end processor, and connectivity via switches. Distinguishing these from simple local device attachments clarifies what truly constitutes a communication network.

Given Data / Assumptions:

• A “basic configuration” should describe communicating endpoints over a link or network.
• Front-end processors concentrate/mediate communications for hosts.
• Switches interconnect multiple links and paths at different layers.

Concept / Approach:
Computer-to-computer and computer-to-front-end processor are standard network configurations. Communication through a data switch reflects switched network designs. In contrast, a computer/peripheral-device configuration describes a local attachment (e.g., a printer or disk) that does not inherently imply networked data communications between intelligent peers; it is an I/O configuration rather than a network configuration. Therefore, it is not counted among basic data communication configurations.

Step-by-Step Solution:

Verification / Alternative check:
Introductory telecom/network texts classify networks by endpoint roles and intermediate devices; I/O peripherals are not considered separate network configurations.

Why Other Options Are Wrong:
They are all legitimate network configurations describing communicating entities or switched fabrics.

Common Pitfalls:
Confusing peripheral buses (USB/SATA) with data networks; assuming any cable implies a network.

Final Answer:
computer/peripheral-device configuration
