Network Bandwidth What is Network Bandwidth? Network bandwidth is the maximum amount of data that can be transmitted over a network connection in a given period, measured in bits per second (bps). Explanation Higher bandwidth allows for faster data transfer and supports more devices and applications simultaneously. It is a critical factor in network performance and user experience. Practical Example of Network Bandwidth A streaming platform upgrades its network bandwidth to handle higher video resolutions and support millions of users without buffering issues.
