The data transfer rate (DTR) is the amount of data in digital form that is moved from one place to another in a given time on a network. As studied before, the greater the bandwidth of a given medium, the higher is the data transfer rate. This can also be referred to as throughput, although data transfer rate applies specifically to digital data streams. Data transfer rate is often measured in bits per second (bps), although the unit baud , which is one bit per second is also used. It is commonly used to measure how fast data is transferred from one location to another. For example, your ISP may offer an Internet connection with a maximum data transfer rate of 4Mbps.
