What is video teleconferencing (VTC) mainly used for?

Video teleconferencing (VTC) is primarily used for communicating through video and voice, allowing participants in different locations to engage in real-time conversations as if they were in the same room. This technology enables face-to-face interaction, which can enhance collaboration, improve understanding, and foster a more personal connection compared to traditional audio calls or text-based communication. VTC is widely utilized in business settings for meetings, presentations, and remote collaboration, making it an essential tool for productivity in an increasingly digital and globalized work environment.

The other options focus on functionalities that do not define video teleconferencing. Text messaging refers solely to written communication without any visual or auditory elements. Editing multimedia documents involves altering content, which is not a feature of VTC that emphasizes live communication. Document storage pertains to saving files for future access, which also falls outside the scope of video and voice communication.
