Data Transfer

Data transfer rate defines average number of data that is transferred per time unit between equipment in a data transmission system. It is usually measured in decimal or binary multiples of bit per second or byte per second.

At the end of 2007, standards and government authorities proposed binary prefixes standard for binary multiplies in order to avoid confusion, ie kilobyle to denote 1000 bytes and kibibyte - 1024 bytes.Read more
