Bandwidth is well-defined as the volume of data that can be transmitted from one point to another in a fixed amount of time. Usually, the bandwidth is expressed in bytes per second or bits per second(bps) for digital devices. Different bandwidths are required for different applications. For example, standard definition (SD) video (480p) works at 1 megabit per second (Mbps), however, high definition (HD) video (720p) works around 4 Mbps, and HDX (1080p), more than 7 Mbps. Primarily, there are 3 categories of bandwidth including, digital bandwidth, data bandwidth and network bandwidth.
