Bandwidth

The Bandwidth calculator computes the average bandwidth based on the amount of data transmitted and the duration of transmission.

INSTRUCTIONS: Choose units and enter the following:

• (D) Volume of Data
• (T) Time to Transmit Data

Bandwidth (B): The calculator average bandwidth in bits per second.  However, this can be automatically converted to compatible units via the pull-down menu.

The Math / Science

Bandwidth is a basic measurement of a server, channel or networks ability to transmit data. The formula for average bandwidth is:

   B = D / T 

where:

• B  = bandwidth of channel, network or server 
• D = volume of data transmitted 
• T = duration of transmission
