Definitionbps stands for bits per second, a unit that expresses transmission speed as the number of bits sent per second.
ExplanationReal line speeds are large numbers, so prefixed forms such as kbps and Mbps are common, using k (10^3), M (10^6), and G (10^9). File sizes are usually given in bytes (B), and since 1 byte = 8 bits, the units must match before you combine them with bps.
Memory hookLowercase b means bit and uppercase B means byte, so "Mbps" and "MB/s" are different amounts.
