Bandwidth definition
Bandwidth is the volume of data that can be transmitted from one point to another in a fixed period of time. Depending on the type of online service, different bandwidths are required. For example, in a standard definition (SD) video (480p) this indicator is set at 1 megabit per second (Mbps), while in high definition (HD) videos (720p) it is raised to 4 Mbps.
