In networking, bandwidth refers to the maximum data transfer rate of a network connection, usually measured in bits per second (bps). It indicates how much data can be sent or received over a network in a given time frame. Higher bandwidth allows for faster transmission of files and smoother performance in applications such as streaming, gaming, and video conferencing. However, it’s important to note that high bandwidth does not always guarantee good performance, as other factors like latency and network congestion also play a role.
