In computer networking, the term "bandwidth" refers to the maximum rate of data transmission across a network connection in a given time period, often measured in megabits per second (Mbps). A higher bandwidth indicates a greater capacity for transmitting more data simultaneously, which can lead to faster internet speeds and improved performance for applications like video streaming, gaming, and file transfers. It is essential for determining how efficiently a network can handle traffic and accommodate multiple users without significant delays or interruptions.
