What is often a consequence of high latency in a network?

High latency in a network primarily leads to delayed data transmission and response times. Latency refers to the time taken for data to travel from the source to the destination, and when this time is prolonged, it can create significant delays in how quickly information is sent or received. This is particularly noticeable in applications that require real-time interaction, such as video conferencing, online gaming, or financial trading. Users may experience lag, causing frustration and impairing the overall effectiveness of the communication or transaction.

The other options relate to different network attributes that do not directly result from high latency. For instance, increased data storage capacity pertains to the ability of a storage system to hold more data, which is independent of latency characteristics. Similarly, enhanced data encryption and improved network security are associated with measures taken to protect data and the network infrastructure itself, rather than issues resulting from high latency. Hence, the correct answer illustrates a direct consequence that users would observe in the performance of a network exhibiting high latency.
