What Is Network Bandwidth And How Is It Measured?
Search Networks, Thursday, July 10th, 2025
Network bandwidth is a measurement indicating the maximum capacity of a wired or wireless communications link to transmit data over a network connection in a given time.
Typically, bandwidth is represented in the number of bits, kilobits, megabits or gigabits that can be transmitted in 1 second. Synonymous with capacity, bandwidth describes data transfer rate, not network speed (a common misconception).
How does bandwidth work?
The more bandwidth a data connection has, the more data it can send and receive at one time. In concept, bandwidth can be compared to the volume of water that can flow through a pipe. The wider the pipe's diameter, the more water can flow through it. Bandwidth works similarly. The higher the capacity of the communication link, the more data can flow through it per second.
