NOTE: Bandwidth also refers to a range of frequencies used to transmit a signal. Instead, the most common Internet bottleneck is your connection to your ISP. Generally, the Internet backbone and connections between servers have the most bandwidth, so they rarely serve as bottlenecks.

Similarly, a download will finish much faster when you have a high-bandwidth connection rather than a low-bandwidth connection.ĭata often flows over multiple network connections, which means the connection with the smallest bandwidth acts as a bottleneck. If you pour the same amount of sand through a wide tube, the sand will finish flowing through the tube much faster. If you pour a large amount of sand into a skinny tube, it will take a long time for the sand to flow through it. When visualizing bandwidth, it may help to think of a network connection as a tube and each bit of data as a grain of sand. Instead, bandwidth measures how much data can flow through a specific connection at one time.
Since data packets travel over electronic or fiber optic cables, the speed of each bit transferred is negligible. While bandwidth is used to describe network speeds, it does not measure how fast bits of data move from one location to another. An Internet connection via cable modem may provide 25 Mbps of bandwidth. For example, a gigabit Ethernet connection has a bandwidth of 1,000 Mbps (125 megabytes per second). It measures how much data can be sent over a specific connection in a given amount of time. Bandwidth describes the maximum data transfer rate of a network or Internet connection.
