Bandwidth

Bandwidth describes the maximum data transfer rate of a network or Internet connection. It measures how much data can be sent over a specific connection in a given amount of time. For example, a gigabit Ethernet connection has a bandwidth of 1,000 Mbps (125 megabytes per second) and an Internet connection via cable may provide 25 Mbps of bandwidth. While bandwidth is used to describe network speeds, it does not measure how fast bits of data move from one location to another. Since data packets travel over electronic or fiber optic

cables, the speed of each bit transferred is negligible. Instead, bandwidth measures how much data can flow through a specific connection at one time. Check out this example for a more in-depth understanding of the concept; Consider a highway, generally each highway contains several lines or bands that determine the capacity of the highway. For example, if a highway includes two lanes, naturally only two cars can cross at one point on the highway, and if a highway includes four lanes, four cars can cross simultaneously. Well now, in this example, we need replacing the car, with the bit, and the highway, with the wire, or the optical fiber, which is actually a means of transmitting the information.

Another excellent example that can help you properly understands this fundamental concept is water pipes. The larger the diameter of the water pipe, the greater the water transfer from one point to another. Just like bandwidth, the more bandwidth we own, the more data we can transfer from point to point. In fact, bandwidth informs precisely you how many bits can be transferred at the same time or can be moved along your communication environment.
