What is Data Transfer Rate?
Data transfer rate is the amount of digital data that moves from one place to another at a given time, in other words the data transfer speed is the speed at which data is transmitted between devices, such as USB , modem, Ethernet, DVD, CD, etc..
The data rate of a computer network connection is normally measured in units of bits per second (bps), kilobits per second (kbps), megabit per second (mbps), gigabit per second (gbps) or terabit per second (tbps).
1 kilobit per second (Kbps) = 1,000 bits per second
1 megabit per second (Mbps) = 1,000 Kbps or one million bits per second.
1 gigabit per second (Gbps) = 1000 Mbps or one million kbits per second.
1 terabit per second (Tbps)= 1000 Gbps or one million mbits per second.
Data rates for non-network equipment are sometimes shown in bytes per second (Bps) rather than bits per second. In those cases,
1 KBps equals one kilobyte per second
1 MBps equals one megabyte per second, and
1 GBps equals one gigabyte per second
One kilobyte (KBps) per second = 8 kilobits per second.
