Bandwith and latency are the measures of computer network speed, or data transfer rate. Bandwidth is the maximum throughput of date in bits per second. Some modems support 100 Gbit/s but speed depends on the hardware and software used. Latency is the delay that network creates during the transfer of data. Users have no or very little control over bandwidth and latency.
Chose the sentences that are False?
