Bandwidth | Machine Vision Glossary

Bandwidth Definition

Bandwidth is the amount of data that can be transmitted over a connection over a fixed period of time (generally seconds). If a bandwidth of a connection is higher, then data will be transmitted faster, and therefore more data can be transmitted over a fixed period of time. Bandwidth is typically defined as the amount of Megabits, Megabytes, or Gigabytes that can be transmitted per second. Typical values for Bandwidth are 40 Megabyte/second (USB2 connection), 100 Megabyte/second (GigE connection) and 400 Megabyte/second (USB3 connection).
