What does "High Bandwidth" mean?

Table of Contents

High bandwidth refers to the ability to transfer a large amount of data in a short time. It is like having a wide road that lets many cars move quickly instead of a narrow street where traffic gets crowded.

In computing and networks, high bandwidth is important because it allows systems to share information faster. This is especially useful for tasks that involve a lot of data, like training complex models in artificial intelligence. When many computers work together, having high bandwidth helps them communicate without delays, making the overall process quicker.

For example, in systems that use multiple processors or accelerators, high bandwidth ensures that all parts can send and receive data rapidly. This leads to better performance and speed, allowing for more efficient operations in various applications, such as optical computing or distributed neural network training.

In summary, high bandwidth helps improve the flow of information, making complex computing tasks quicker and more efficient.
