What does the term 'bandwidth' measure?

The term 'bandwidth' measures the amount of data that can travel over a connection within a specific timeframe. It indicates the maximum capacity of a network connection to transmit data, typically expressed in bits per second (bps). A higher bandwidth allows for more data to be transmitted simultaneously, which is especially important in virtual events where multiple participants may be streaming video, sharing presentations, and engaging in real-time communications.

Understanding bandwidth is crucial for planning virtual events, as it affects the quality and reliability of the event experience. Insufficient bandwidth can lead to lag, buffering, and interruptions, negatively impacting participant engagement. Thus, when considering the options presented, the measure of bandwidth directly relates to its role in managing data transfer effectively during online meetings and events.

While the speed of an internet connection is related to bandwidth, it does not encompass the entire concept since speed can vary independently of the maximum capacity of data transfer. The size of video files and the number of attendees do not relate directly to bandwidth either; those factors might influence bandwidth usage but do not define it. Therefore, the focus on the data capacity element in the definition of bandwidth is what makes this answer the correct choice.
