Bandwidth comes as either fixed bandwidth or burstable bandwidth. If a company attempts to transmit past its fixed limit, their data packets are dropped when using fixed bandwidth. Burstable bandwidth offers regular data usage. However, if a company needs a larger capacity, their bandwidth can burst as needed to serve everybody's needs. \tn % Row Count 17 (+ 17) % Row 1 \SetRowColor{white} Speed & The time between when a device sends a signal to a server and when that signal is answered by the server and sent to each person's device is their internet speed or latency. Higher speeds add up to higher costs. \tn % Row Count 26 (+ 9) % Row 2 \SetRowColor{LightBackground} Quality & Connection quality includes speed and whether there is jitter or packet loss. Jitter, or when data packets arrive at different times, results in delays in audio or video. Packet loss is when data packets don't arrive or arrive out of order or late. All of this adds up to low-quality connections. \tn % Row Count 39 (+ 13) \end{tabularx} \par\addvspace{1.3em} \vfill \columnbreak \begin{tabularx}{5.377cm}{x{1.89126 cm} x{3.08574 cm} } \SetRowColor{DarkBackground} \mymulticolumn{2}{x{5.377cm}}{\bf\textcolor{white}{Factors that influence DIA pricing.

On-net DIA, which does not require a connection to be built, is less expensive.
