What Is bps?

Bits per second explained

bps stands for bits per second. A bit is the smallest common unit of digital information. When a connection is described as 100 Mbps, it means a theoretical rate of 100 million bits per second.

bps, Kbps, Mbps and Gbps

Bits are not bytes

Network speeds usually use lowercase b for bits. File sizes and transfer speeds often use uppercase B for bytes. One byte contains eight bits, so 100 Mbps corresponds to a theoretical maximum of 12.5 MB/s.
