High bandwidth refers to a network's ability to transmit large amounts of data quickly and efficiently. Measured in megabits per second (Mbps) or gigabits per second (Gbps), higher bandwidth means more data can flow through the network at a given time, resulting in faster internet speeds, reduced latency, and better overall performance.

A common use case for high bandwidth is cloud computing and video streaming, where large data transfers require a stable and fast connection. Businesses rely on high-bandwidth networks for VoIP communications, real-time collaboration, and data-intensive applications like AI and big data analytics. With the growing demand for remote work, IoT, and 5G technology, high bandwidth ensures seamless connectivity, minimal buffering, and enhanced user experiences across digital services.
