What is an example of communication technology?

Communication technology refers to tools and systems that facilitate the exchange of information and communication between individuals or groups. The option that represents this concept most clearly is the video conferencing tool, as it enables real-time interaction and communication over distances, which embodies the primary purpose of communication technology.

Using a video conferencing tool allows users to see and hear each other in real time, effectively bridging geographical gaps and enhancing the quality of communication, whether for personal or professional purposes. This type of technology has become increasingly important, especially in scenarios where face-to-face interaction is not feasible.

In contrast, the physical notary stamp, while essential for the notary's duties, serves as a tangible item rather than a means of communication. The computer application for scheduling appointments is valuable for organization and management but does not necessarily facilitate direct communication between parties. Similarly, a printed identification card serves identification purposes, not communication. Thus, the video conferencing tool stands out as the only option that embodies the essence of communication technology.
